The tomb of Kairsu is located north of the pyramid of Neferirkare and is part of a so far unexplored cemetery dating to the
reign of Neferirkare – Nyuserre. The mastaba features several highly unusual characteristics. Basalt blocks had been used for
the pavement in front of the façade and in the chapel. To date, it is the only attestation of such a practice in a non-royal tomb
in the Old Kingdom. Some of the titles of Kairsu show that he was a high ranking official. Kairsu was overseer of all royal
works of the king and foremost of the House of Life. There was a very close link established between this institution, which
was in fact a centre of knowledge and wisdom in the Old Kingdom, and the god of creation Khnum. It is also important that
the House of Life appears from the reign of Nyuserre when Osiris is attested for the first time. Another important feature
of the tomb is the fact that the statue of the tomb owner was placed in front of the sarcophagus. This only confirms the
previous assumption that ancient Egyptians were placing statues not only in different areas of tombs’ superstructures but
also in the burial chambers. There is a strong possibility that the owner of the tomb may be identical to the famous sage
of Egyptian history, who, according to a much later tradition, was author of the Loyalist teaching, Teaching for Kagemni and
Teaching of Kairsu and also father of the early Sixth Dynasty vizier Kagemni.

A new data block concerning diverse palaeoecological / bio-economic aspects, obtained through the use of natural science research methods is introduced to scientific turnover. The block consists of several separate investigations: palaeobotanical one (determination of cultivated plants and weeds, and tree species) and archaeozoological one (teriology, ichthyology, malacology). Materials for the analysis of four of the five areas (except teriological one) obtained thanks to the expanding of traditional archaeological research methods by applying flotation and panning.
A careful analysis of this block and a comparison between natural sciences data obtained independently, and also their comparison with markers of bio-economic activities, provides reliable justification for complex analysis that results in a reconstruction of ecology, environment and bio-economic activities of inhabitants of Severynivka hillfort in Antiquity.
The materials obtained also show the high efficiency and prospects of using thorough research methods on settlements, and owing to these methods the base for the comprehensive interdisciplinary approach to the treatment of various organic remains is accumulated. Such approach allows widening significantly the sources for study bio-economic activity of ancient inhabitants of Severynivka microregion as well as detailing the palaeoecological aspects of their life.
Keywords: Scythians, hillfort, flotation, panning, palaeoecology, palaeoethnobotany, archaezoology, bioresources, comprehensive analysis, bio-economic activity.

The paper presents results of multidisciplinary studies on environmental archaeology undertaken on complex of prehistoric and early historic settlements located at Złotoria village in north-eastern Poland. Relicts of settlements dated to the Stone Age, the Late Bronze Age, the Early Iron Age, the Roman Period and the Early Medieval Period have been uncovered at two sites at Złotoria. On both sites analysis including: archaeological research, geoarchaeological, palaeobotanical (i.e. pollen, macrofossils like fruits, seeds, wood and charcoal) and palaeozoological (Cladocera, bone remains from archaeological contexts) was performed. The profile of organic sediments of palaeochannel fillings has been collected and palaeoecological analyses of sediments have been elaborated as well.
Both sites have been situated on sandy ground, one of them (site no. 53) on deluvial sediments, and the second (site no. 56) on river terrace and slope of the Narew River valley. The settlement complex has been established on the one hand at the most suitable place for crossing the Narew River and on the other hand in the area featured by high geo- and biodiversity.

Hill fort Sverdlovske-1 is located on the right bank of the Desna River on a promontory overlooking the river valley at 45—50 m (Figs. 1; 4). The monument has been known for about 150 years; stationary studies were started in 1968 by O.M. Mel’nikovs’ka, and conducted after by O.Ye. Chernenko from 2014.
As a result of recent research of the hill-fort, a new data regarding its paleoecology and bio-economic specifics were obtained through the use of natural science methods in addition to the classic archaeological techniques. The present paper comprises a number of separate studies: palaeobotanical (definition of cultivated plants and weeds, trees) and archaeozoological (theriology, ornithology, ichthyology). Materials for the analysis were obtained due to the expansion of traditional archaeological techniques through the use of flotation and washing, as well as classical methods of research in archeology (Fig. 2). Filtering of the soil was held in the construction no. 1, investigated on the settlement in 2016 (Fig. 3).
Paleoetnobotanical materials came from three different samples; macrofossils are represented by typical medieval species — grain crops: Secale cereale (rye), Hordeum vulgare (barley), Triticum aestivum s. l. (soft wheat), Triticum dicoccon (emmer wheat), Panicum miliaceum (millet), Avena sp. (oats); also Cerealia (not defined to species or genus level); leguminous plants: Pisum sativum (pea), Lens culinaris (lentil), as well as the small number and variety of weeds, namely Convolvulus arvensіs (field bindweed), Setaria sp. (foxtail). However, the proportion of cultural grain crops in palaeoethnobotanical spectrum by weight is somewhat different from the synchronous counterparts (Figs. 5—7; Tables 1—3). The analysis of all data may indicate not only the high level of farming, but also a good adaptability to natural conditions. An indirect confirmation of agriculture and its role for inhabitants of the Sverdlovske I are holes that could be used for grain storage (Fig. 11, 1) and the finds of pans to dry grain (and maybe for cooking bread; Fig. 12).
Analysis of wood remains suggests the use of trees, which are traditional for this region — oak (Quercus sp.) and pine (Pinus sylvestris). Their wood was used for the production needs such as building and heating (Table 4).
Analysis of bone remains belonging to mammals (Tables 5; 6; 10; Figs. 8; 13—14) indicates the possibility of maintenance of herd in the stall period and, accordingly, the development of animal husbandry, which was typical for Slavs during the 1st millennium AD (the prevalence of cattle in a herd and meat production, the importance of pigs (by number) and horses (for meat); an auxiliary role of small livestock). The findings of spindles indicate the usage of raw materials for the manufacture of tissue from agriculture and / or stockbreeding (Fig. 15).
At the same time, the proportion of hunting, both in the number of individuals and in the meat volume, was about 30 % — it is significantly enough to recognize the important role of hunting in the life of the ancient inhabitants of Sverdlovske-1. It should be also noted that the hunting have had both meat and fur-bearing orientation.
Both industries associated with obtaining or production of meat in large quantities, also supply raw materials for various kinds of crafts. Numerous bone wares were found in the archaeological material from the Sverdlovske-1 (Fig. 17).
Ornithological studies have established the prevalence of wild birds in the number of species and individuals (Anas platyrhynchos, Anas crecca / quercuedula, Clangula hyemalis, Ardea cinerea, Lyrurus tetrix, Perdix perdix — seven individuals) over the poultry (Gallus domestica — four individuals; Anser anser / Anser anser f. domestica — one individual) (Table 7). These data also favor the importance of the appropriating economy.
Fishing (Table 8; 9) is represented by eight fish species (mainly pike Esox lucius, perch Perca fluviatilis, catfish Silurus glanis and zander Sander lucioperca; less numerous were roach Rutilus rutilus, bream Abramis brama, asp Aspius aspius, and carp Cyprinus carpio). Such composition indicates the importance of individual fishing. There were also tackles for mass fish catch, as evidenced by finds of clay weights for nets (Fig. 16), as well as possible tools for their weaving (Fig. 17).
The analysis of bio-economic activity carried out by inhabitants of the Sverdlovske-1 hill fort indicates the maximum and rational use of products from playback economy (agriculture, livestock), and from foraging (hunting, fishing, the role of collecting is not confirmed yet, although its important role is hypothetically undeniable) (Fig. 10). This is also evidenced by the attempt of comparison of food derived from various sectors of the economy (Fig. 18).

A new exceptionally preserved marginal marine biota is reported from the Late Ordovician Big Hill Formation of Stonington Peninsula in Michigan's Upper Peninsula. The new Lagerstätte hosts a moderately diverse fauna of medusae, linguloid brachiopods, non-mineralized arthropods and orthocone nautiloids, alongside dasycladalean green algae. The biota is similar to those of Lagerstätten from the Late Ordovician of Canada, revealing an extensive distribution of a distinctive marginal marine palaeocommunity in Laurentia at this time. The Big Hill biota extends the geographical range of exceptionally preserved Late Ordovician faunas in Laurentia and indicates that further examples remain to be discovered.

The celebrated fossil locality of Tendaguru (Tanzania, East Africa) has been well known for its unique Late Jurassic dinosaur assemblages since the early decades of the 20th century. Recently, within the scope of the GermamTanzanian Tendaguru project, an expedition returned to Tendaguru with the aim of collecting microvertebrates, micrci-and niacroinvertebrates. plant fossils and new sedimentological and stratigraphical data. Applying a multidisciplinary research approach. the data collected were used to address various controversial issues regarding the Tendaguru Beds. These include their exact age. depositional cnvii-onmcnts and reconstructions of the palaeoecosystems in which the dinosaurs lived.

We review the Triassic record of terrestrial plants and animals from the Southern Alps at more than 60 sites. The Triassic tetrapod track record seems to mirror the global body fossil record of diapsids (with the exception of the Olenekian record), but is almost completely devoid of synapsids and amphibians. During the Bithynian-Pelsonian interval (early-late Anisian, Middle Triassic) the ichnoassociation documents a diverse tetrapod fauna composed of lepidosauromorphs, basal amniotes, archosauriformes (“rauisuchians”) and possible dinosauromorphs, whereas the body fossil fauna is represented only by small lepidosauromorphs and archosauriformes (“rauisuchians”). The rich flora is one of the best examples of early recovery of ecosystems after the Permo-Triassic event. The Illyrian (late Anisian, Middle Triassic) ichnoassociation reflects a faunal composition of lepidosauromorphs, archosauriformes and dinosauromorphs, while the body fossil assemblage is only
represented by a few remains of archosauromorphs. Tetrapod footprints are missing from the Fassanian (early Ladinian, Middle Triassic), while scattered skeletal remains document the presence of large and small archosauromorphs. Fassanian plant fossils record a flora dominated by conifers and seed ferns. The Longobardian body fossil record (late Ladinian, Middle Triassic) documents the presence of archosauromorphs and mammallike-
reptiles, whereas tracks are completely absent. During this period, floras still show some typical Early-Middle Triassic elements and are dominated by conifers. The Longobardian fossil record is biased by taphonomic selection, as these specimens are found only in basinal successions. Middle and early Late Triassic rich plant fossil associations record some interesting evolutionary trends, such as the radiation of modern fern families and the appearance of entire new groups (e.g., the bennettitaleans). During the Carnian (Late Triassic) the flora reaches its highest diversity and shows the first occurrence of
unequivocal bennettitaleans and the first putative cheirolepidiacean conifers. From the latest Carnian to the end of
the Norian (Late Triassic), faunal associations are dominated by dinosaurs, while archosauriformes, drepanosaurids,
protorosaurs, pterosaurs, lepidosauromorphs, “rauisuchians” and dinosauromorphs are only minor components of the fauna. Norian floras are poorly known but seem to be dominated by conifers, with rare fragments of Bennettitales.
The numerous tetrapod track associations provide a series of snapshots trough time that show a huge increase in variability reflecting the morphological diversity spanning from a stem-amphibian to a crurotarsan to a dinosaur foot. The nearly-complete absence of non-diapsid tetrapods appears to be possibly correlated with the paucity of fluvial-lacustrine environments, while the dominance of dinosaurs in the Norian has to be understood in the context of a monotonous, harsh, carbonate-platform environment. The Norian sites document the presence of a variety of archosaurs, prolacertiforms and lepidosauromorphs whose diversification may have been the result of strong evolutionary pressures triggered by the unstable environment.

The paper presents results of multidisciplinary studies on environmental archaeology under-taken on complex of prehistoric and early historic settlements located at Złotoria village in northeastern Poland. Relicts of settlements dated to the Stone Age, the Late Bronze Age, the Early Iron Age, the Ro-man Period and the Early Medieval Period have been uncovered at two sites at Złotoria.

Based on materials from Monastyrok hill-fort, fishery of the Early Slavs from the Dnipro River (middle region) is analyzed in this paper. A comprehensive study of the circumstances in which ichthyological remains and fishing tackle were uncovered, as well as the comparative analysis of the latter was conducted. As a result, a conclusion is made that the fish-hooks belong to the Early Slavonic period of the hill-fort. In addition, owing to the work with the collections of the N national Museum of Natural history of the national Academy of Sciences of Ukraine, uncovered and attributed was the ichthyologic material from the site describing the industrial fish species in the Early Slavonic period.
Ichthyologic identification showed that at least 10 fish species of 9 genera and 5 families were encompassed into the fishery. The majority of these remains belong to fish of prey: pike, catfish, zander, and perch; sturgeons and carp fishes are represented by single bones. numerous findings of cranium bones are indisputable evidence for fishery, but not fish import. The method of reconstruction the weight and body size of single fish individuals showed that big mature fishes prevailed in catch. O owing to this reconstruction, it is ascertained that both tackle for individual (with hooks), and mass (with nets) catch were used.
The data obtained convincingly prove the importance of fishery in vital activity of population at the Monastyrok hill-fort and of all the East Slavs habituating the middle region of the Dnipro River in the period from the 8th to the 13th centuries AD. The species and size diversity of industrial fish is an indirect evidence for the usage of both tackle types: of individual (with hooks) and mass (with nets) catch. Analysis of the context of the hooks’ finds testifies for their usage mainly in the Early Slavonic period of the Monastyrok hill-fort existence.

Background
Few studies on eurypterids have taken into account morphological changes that occur throughout postembryonic development. Here two species of eurypterid are described from the Pragian Beartooth Butte Formation of Cottonwood Canyon in Wyoming, and included in a phylogenetic analysis. Both species comprise individuals from a number of instars, and this allows for changes that occur throughout their ontogeny to be documented, and how ontogenetically variable characters can influence phylogenetic analysis to be tested.
Results
The two species of eurypterid are described as Jaekelopterus howelli (Kjellesvig-Waering and Størmer, 1952) and Strobilopterus proteus sp. nov. Phylogenetic analysis places them within the Pterygotidae and Strobilopteridae respectively, both families within the Eurypterina. Jaekelopterus howelli shows positive allometry of the cheliceral denticles throughout ontogeny, while a number of characteristics including prosomal appendage length, carapace shape, lateral eye position, and relative breadth all vary during the growth of Strobilopterus proteus.
Conclusions
The ontogeny of Strobilopterus proteus shares much in common with that of modern xiphosurans, however certain characteristics including apparent true direct development suggest a closer affinity to arachnids. The ontogenetic development of the genital appendage also supports the hypothesis that the structure is homologous to the endopods of the trunk limbs of other arthropods. Including earlier instars in the phylogenetic analysis is shown to destabilise the retrieved topology. Therefore, coding juveniles as individual taxa in an analysis is shown to be actively detrimental and alternative ways of coding ontogenetic data into phylogenetic analyses should be explored.

Peatlands are important records of past environmental changes. Based on a multiproxy analysis, the main factors influencing the evolution of a peatland
can be divided into autogenic and allogenic. Among the important allogenic factors, apart from climate change, are deforestation and drainage, which
are directly associated with human impact. Numerous consequences arise from these processes, the most important of which are physical and chemical
denudation in the catchment and the related hydrological disturbances in the catchment and peatland. The present study determined how human
activities and the past climatic variability mutually influenced the development of a small peatland ecosystem. The main goals of the study were: (1) to
trace the local changes of the peatland history over the past 600 years, (2) to investigate their relationship with changes in regional hydroclimate patterns,
and (3) to estimate the sensitivity of a small peatland to natural and human impact. Our reconstructions were based on a multiproxy analysis, including
the analysis of pollen, macrofossils, Chironomidae, Cladocera, and testate amoebae. Our results showed that, depending on the changes in water level,
the history of peatland can be divided into three phases as follows: 1/the phase of stable natural conditions, 2/phase of weak changes, and 3/phase of

the evolution of the studied peatland ecosystem, we compared data from two peatlands – large and small – located close to each other. The results of

can be divided into autogenic and allogenic. Among the important allogenic factors, apart from climate change, are deforestation and drainage, which
are directly associated with human impact. Numerous consequences arise from these processes, the most important of which are physical and chemical
denudation in the catchment and the related hydrological disturbances in the catchment and peatland. The present study determined how human
activities and the past climatic variability mutually influenced the development of a small peatland ecosystem. The main goals of the study were: (1) to
trace the local changes of the peatland history over the past 600 years, (2) to investigate their relationship with changes in regional hydroclimate patterns,
and (3) to estimate the sensitivity of a small peatland to natural and human impact. Our reconstructions were based on a multiproxy analysis, including
the analysis of pollen, macrofossils, Chironomidae, Cladocera, and testate amoebae. Our results showed that, depending on the changes in water level,
the history of peatland can be divided into three phases as follows: 1/the phase of stable natural conditions, 2/phase of weak changes, and 3/phase of
significant changes in the catchment. Additionally, to better understand the importance of the size of catchment and the size of the depositional basin in

Ein Jahrtausend lang (395-1453 n. Chr.) prägte das Byzantinische Reich den östlichen Mittelmeerraum. Die gut erhaltenen Ruinenstädte von Caričin Grad, Ephesos oder Palmyra mit ihren Kirchen und Mosaiken führen uns eindrucksvoll seine Pracht und Wirkmächtigkeit vor Augen. In diesen urbanen Zentren spielte sich aber nur ein Bruchteil des byzantinischen Lebens ab. Der größte Teil der Bevölkerung arbeitete in der Landwirtschaft, der Fischerei, dem Handwerk und dem Handel.
Diese Tätigkeiten waren weitgehend mit Tieren oder tierischen Rohstoffen verbunden und führten die Menschen hinaus auf die steinigen Äcker, in die Auwälder, in die Berge und auf das Meer. Dieses Buch geht der Frage nach, wie Menschen im Byzantinischen Reich Tiere nutzten und damit ihre Umwelt prägten und veränderten. Aber auch der Aspekt, wie sich Tiere den Aktivitäten der Menschen anpassten, wird beleuchtet. Wie nutzten sie die menschlichen Infrastrukturen? Historisch-archäologische Forschungen, naturwissenschaftliche Methoden, schriftliche Quellen und bildliche Darstellungen geben einen Eindruck vom fächerübergreifenden Instrumentarium, das uns heute zur Verfügung steht, um dieses zukunftsweisende Feld der Altertumskunde zu untersuchen. Und auch der byzantinischen Umwelt wird auf diesem Wege wieder etwas Leben eingehaucht.

The Żabieniec kettle hole is the first peatland in central Poland analyzed quantitatively with four biotic proxies (plant macrofossils, pollen, testate amoebae and chironomids) to reconstruct the past environmental change. Palaeoecological data were supported by historical and archaeological records. We focused on autogenic vegetation change and human impact in relation to climatic effects. The aims of our study were (a) to describe the development history of the mire during the last 2,000 years, (b) to date and reconstruct the anthropogenic land-use changes and (c) to discuss a possible climatic signal in the peat archive. The combination of proxies revealed dramatic shifts that took place in the peatland since the Roman Period. Żabieniec was a very wet telmatic habitat until ca. AD 600. Then, the water table declined, and the site transformed into a Sphagnum-dominated mire. This dry shift took place mainly during the Early Medieval Period. Human impact was gradually increasing, and it was particularly emphasized by deforestation since AD 1250 (beginning of the Late Medieval Period). Consequently, surface run-off and aeolian transport from the exposed soils caused the eutrophication of the mire. Furthermore, chironomids and testate amoebae reveal the beginning of a wet shift ca. AD 1350. Openness considerably increased in the Late Medieval and the Modern Periods. The highest water table during the last 1,000 years was recorded between AD 1500 and 1800. This wet event is connected with deforestation, but it could be also associated with the Little Ice Age. Our study shows plant succession in the Żabieniec peatland, which can be explained with the recent landscape transformation. However, such changes are also possibly linked with the major climatic episodes during the last two millennia, such as the Medieval Warm Period and the Little Ice Age.

Aim Within the last several decades, Grévy's zebra (Equus grevyi) has undergone a massive reduction in geographical range and population size, largely as the result of human impacts. To place its recent decline in a deeper prehistoric context, and to understand the factors mediating its range and abundance over geological time frames, this study examines the fossil history of Grévy's zebra in equatorial East Africa.

A total of 79 ostracode species were recognized from the embayment sediments deposited during the Late Pleistocene Shimosueyoshi transgression in central Japan. The most dominant species was Neomonoceratina delicata, now abundant in tropical inner bays of the Ryukyu Islands, the South China Sea and southeastern Asia. Bicornucythere bisanensis, widely dominant species in enclosed middle muddy bays of temperate climatic zones in Japan and northern China, was also abundant in the middle and upper sequences. Most of the other main species were assigned to the "Japonic elements" and are presently common in tropical or subtropical and temperate shallow seas near the Japanese Islands. Four ostracode biofacies were identified using the Q-mode cluster analysis. A change in water depth was clearly revealed in the study sequence, based on the vertical changes in the biofacies and the relative abundances of fossil ostracode species. The single most dominant species, N. delicata, does not currently exist in the Japanese Islands north of the Tokara Strait (Watase's line: one of zoological lines of demarcation), in southern Japan. Based on a compilation of fossil and recent distribution records, it is believed that N. delicata migrated from the south of the Tokara Strait by the marine oxygen isotope stage (MIS) 11 (∼ 430 ka), dominated other species in enclosed muddy bays and then spread to the northernmost areas during the MIS 5. However, almost all populations of this species probably disappeared north of the Tokara Strait during the Last Glacial Maximum due to a decrease in water temperature. This species could not survive colder water temperature and could not migrate north through the Tokara Strait during the postglacial transgression because the strait has been deep and wide since the Early Pleistocene. We conclude that this species lived commonly during the glacial stages of MIS 10, 8 and 6 north of the Tokara Strait because of the favorable water temperature for reproduction.

Excavations at the Ille site in north Palawan have produced a large Terminal Pleistocene to Late Holocene faunal assemblage. Derived both from the natural deaths of small mammals and the human hunting of large and intermediate game, the bone assemblage provides important new information about changes in the composition and structure of the mammal community of Palawan over the last ca. 14 000 years. The Ille zooarchaeological record chronicles the terrestrial vertebrate fauna of the island, and the disappearance of several large taxa since the end of the last glacial period due to environmental change and human impacts.

The assemblages of vertebrate microfauna gained from the owl’s pellets can tell us not only about the composition of the owl’s diet, but also about the composition of the surrounding environment. Our remains came from the Old Kingdom mastaba (AC 29) located in the Abusir necropolis (Egypt); they were unearthed during the spring season of 2013 from the bottom of a burial shaft and an adjacent burial chamber. The tomb was robbed and partially destroyed during the First Millennium B.C. – it seems that niches in the shaft and the burial chamber were used as a nesting place by owls in this period until the shaft was filled by deserts and again. Fortunately, several owls’ pellets were uncovered in
a good state of preservation and can be determined as belonging to the Common Barn-owl (Tyto alba). The dominant part of the assemblage (ca 2/3 of individuals) was formed by small and medium-sized rodents (mainly the House Rat and House Mouse, occasionally also gerbils and the Three-toed Jerboa). A substantial part of the assemblage was also made by the white-toothed shrews (18.32 %) and frogs (10.79 %). A small amount of small birds(singing birds and quails) and sporadic finds of beetles, bats or snake were also recorded.
The species composition reflects an environment strongly influenced by human occupation, with an admixture of species of semi-deserts/deserts, species of grassland/fields and species of river banks/shallow waters. Compared to a recent assemblage of the barn-owl pellets, the species composition of the older diet is more diverse, with the occurrence of poorly known species, and reflecting changes in the surrounding environment.

ABSTRACT: Previously enigmatic, ovoid to sac-like fossils of organic, acid resistant substance which are common components of leaf cuticle and megaspore assemblages in limnic and terrestrial palaeoen- vironments are identified as cocoons of clitellates. They have been recorded for a long time by palaeobotanists and palynologists, particularly in the Mesozoic, and have been variously interpreted as being of megaspore, seed, or algal origins, although convincing homologues were lacking. The fossils agree in basic wall construction with cocoons of clitellates, and particularly with certain members of the Hirudinea. A clitellate affinity is further supported by a possible segmentation, their consistently non-marine occurrence, evidence for predation, and an example of amber-like inclusion of alien structures in the cocoon wall which indicates the presence of secretion. As a consequence of the new interpretation, two taxa established under the botanical code of nomenclature for such fossils, namely Burejospermum crassitestum Krassilov and Dictyoth- ylakos pesslerae Horst, are transferred to the zoological kingdom and classified under Clitellata (phylum Annelida), along with two new taxa, D. spitsbergensis sp.n. andPilothylakospilosus gen. et sp.n. With the present interpretation a consistent Mesozoic record is documented for clitellates, a group of softbodied, basically freshwater and terrestrial animals of which there was until now nearly no fossil record.

The Ner River valley (central Poland) underwent substantial transformation during the Weichselian–Holocene transition as a result of fluvial processes and climate changes, resulting in the establishment of its present shape in the Holocene. A multiproxy study based on organic deposits from a palaeochannel fill (Lutomiersk– Koziówki) shows that after the channel was cut off during the late glacial termination, it became a shallow oxbow, fed by local springs. In the Boreal period, the oxbow lake was also fed by precipitation and became a telmatic environment overgrown by rush and swamp vegetation. Finally, it was covered by overbank deposits. The first flooding phase (9900–9600 cal. BP) was followed by the accumulation of overbank sediments (after 9500 cal. BP) and flooding increased after ca. 9300–9000 cal. BP. Pollen data provide information on the regional vegetation context for local and regional changes. In the Atlantic period, an increase in both summer and winter temperatures is inferred from the pollen data, corresponding to an expansion of thermophilous deciduous forests. While in general, flooding phases of the Early Holocene are poorly recognised in Eastern Europe, the Lutomiersk–Koziówki site may be considered as one of the reference points for this phenomenon in the region.

Background. The origin of turtles, their earliest evolution and the homologies of the elements building their shell are still enigmatic and remain an object of ongoing discussion and research. Although the oldest fully shelled turtle – Proterochersis robusta from the Lower Stubensandstein (Norian) of Germany – was described more than a century ago, until recently it was mostly ignored by researchers. This is surprising, not only because of its notable stratigraphic position, but also due to the critical significance of this taxon in two competing hypotheses of turtle interrelationships. The divergence time of two main branches of Testudines crown group depends on whether Proterochersis is a basal pleurodire or a stem turtle.
Methods. A detailed study of the German material of Proterochersis and Murrhardtia was performed by the author and the available specimens were compared with still growing collection of proterochersid remains from the Norian location in Poręba (Poland).
Results. Two controversial taxa from Germany, Proterochersis intermedia and Murrhardtia staeschei are proved to be the synonyms of P. robusta. Establishment of another two proterochersid taxa is proposed and new primitive postcranial characters are recognized, supporting the stem position of Proterochersidae on the turtle phylogenetic tree.
Discussion. Two general hypotheses concerning the split time of Cryptodira and Pleurodira are functioning in the literature, and Proterochersis plays a crucial role in these considerations. According to traditional view, this taxon is the oldest side-necked turtle, based on the sutural connection between its pelvis and shell. Numerous recent analyses tended to allocate the Pleurodira much higher on the tree, resulting in stem position of Proterochersis, though such placement usually lacked a strong support. This was caused by an incompletness of Proterochersis material (only shells) and errors in interpretation of some characters. New data, gathered mostly from the Polish – much more complete and well preserved – specimens, supports the basal position of Proterochersidae and provides new insights in the ancestral structure of the turtle shell.

The celebrated fossil locality of Tendaguru (Tanzania, East Africa) has been well known for its unique Late Jurassic dinosaur assemblages since the early decades of the 20th century. Recently, within the scope of the GermamTanzanian Tendaguru project, an expedition returned to Tendaguru with the aim of collecting microvertebrates, micrci-and niacroinvertebrates. plant fossils and new sedimentological and stratigraphical data. Applying a multidisciplinary research approach. the data collected were used to address various controversial issues regarding the Tendaguru Beds.

The Late Jurassic to Early Cretaceous Tendaguru Beds (Tanzania, East Africa) have been well known for nearly a century for their diverse dinosaur assemblages. Here, we present sedimentological and palaeontological data collected by the German-Tanzanian Tendaguru Expedition 2000 in an attempt to reconstruct the palaeo-ecosystems of the Tendaguru Beds at their type locality. Our reconstructions are based on sedimentological data and on a palaeoecological analysis of macroinvertebrates, microvertebrates, plant fossils and microfossils (ostracods, foraminifera, charophytes, palynomorphs). In addition, we included data from previous expeditions, particularly those on the dinosaur assemblages.The environmental model of the Tendaguru Beds presented herein comprises three broad palaeoenvironmental units in a marginal marine setting: (1) Lagoon-like, shallow marine environments above fair weather wave base and with evidence of tides and storms. These formed behind barriers such as ooid bar and siliciclastic sand bar complexes and were generally subject to minor salinity fluctuations. (2) Extended tidal flats and low-relief coastal plains. These include low-energy, brackish coastal lakes and ponds as well as pools and small fluvial channels of coastal plains in which the large dinosaurs were buried. Since these environments apparently were, at best, poorly vegetated, the main feeding grounds of giant sauropods must have been elsewhere. Presumably, tidal flats and coastal plains were visited by dinosaurs primarily during periods of drought. (3) Vegetated hinterland. Vegetation of this environment can only be inferred indirectly from plant material transported into the other depositional environments. Vegetation was dominated by a diverse conifer flora, which apparently formed part of the food source of large herbivorous sauropods. Evidence from various sources suggests a subtropical to tropical palaeoclimate, characterised by seasonal rainfall alternating with a pronounced dry season during the Late Jurassic. In Early Cretaceous times, sedimentological and palaeontological proxies suggest a climatic shift towards more humid conditions.Die Tendaguru-Schichten von Tansania in Ostafrika (Oberjura bis Unterkreide) sind als Lagerstätte oberjurassischer Dinosaurier seit nahezu einem Jahrhundert weltweit bekannt. Anhand von sedimentologischen und paläontologischen Daten, die während der Deutsch-Tansanischen Tendaguru Expedition 2000 im Typus-Gebiet der Tendaguru-Schichten gewonnen wurden, werden Paläo-Ökosysteme rekonstruiert. Grundlage der Rekonstruktionen sind die Auswertung sedimentologischer Daten sowie die paläo-ökologische Analyse von Makroinvertebraten, Mikrovertebraten, pflanzlichen Fossilien und Mikrofossilien (Ostrakoden, Foraminiferen, Charophyten, Palynomorphen). Darüber hinaus werden Informationen über Dinosaurier berücksichtigt, die bei früheren Expeditionen gewonnen wurden.Das hier vorgestellte Ablagerungsmodell der Tendaguru-Schichten umfaßt drei Teilbereiche eines randlich marinen Sedimentationsraumes, die wie folgt gekennzeichnet werden können: (1) Lagunen-artige, marine Flachwasserbereiche, die oberhalb der Schönwetter-Wellenbasis lagen und unter deutlichem Einfluß von Gezeiten und Stürmen standen. Sie waren vom offenen Meer durch Barrieren, wie Ooidbarren und siliziklastischen Sandbarrenkomplexen, getrennt und wiesen einen leicht schwankenden Salzgehalt auf. (2) Ausgedehnte Wattgebiete und flache Küstenebenen. Dort befanden sich niedrig-energetische, brackische Strandseen und Teiche sowie Tümpel und kleinere Flußrinnen, in denen die großen Dinosaurier eingebettet wurden. Da diese Lebensräume bestenfalls dürftig bewachsen waren, müssen die Nahrungsquellen und der eigentliche Lebensraum der riesigen Sauropoden anderswo gelegen haben. Vermutlich wurden die Wattgebiete und Flachküsten von Dinosauriern vorrangig in den Trockenzeiten aufgesucht. (3 ) Bewachsenes Hinterland. Die Vegetation dieses Lebensraumes kann nur indirekt aus Pflanzenresten erschlossen werden, die in die anderen Ablagerungsraume transportiert wurden. Die Vegetation wurde von einer diversen Koniferenflora dominiert, die zumindest teilweise die Nahrungsgrundlage der großen, herbivoren Sauropoden bildete. Sedimentologische und paläontologische Indikatoren sprechen für ein subtropisches bis tropisches Klima wahrend der späten Jurazeit mit einem jahreszeitlichen Wechsel von Regenfällen und ausgeprägten Trockenzeiten. In der frühen Kreidezeit deutet sich ein Wechsel zu starker humiden Bedingungen an.

Peatlands are important records of past environmental changes. Based on a multiproxy analysis, the main factors influencing the evolution of a peatland can be divided into autogenic and allogenic. Among the important allogenic factors, apart from climate change, are deforestation and drainage, which are directly associated with human impact. Numerous consequences arise from these processes, the most important of which are physical and chemical denudation in the catchment and the related hydrological disturbances in the catchment and peatland. The present study determined how human activities and the past climatic variability mutually influenced the development of a small peatland ecosystem. The main goals of the study were: (1) to trace the local changes of the peatland history over the past 600 years, (2) to investigate their relationship with changes in regional hydroclimate patterns, and (3) to estimate the sensitivity of a small peatland to natural and human impact.

The paper presents results of multidisciplinary studies on environmental archaeology under-taken on complex of prehistoric and early historic settlements located at Złotoria village in northeastern Poland. Relicts of settlements dated to the Stone Age, the Late Bronze Age, the Early Iron Age, the Ro-man Period and the Early Medieval Period have been uncovered at two sites at Złotoria. On both sites analysis including: archaeological research, geoarchaeological, palaeobotanical (i.e. pollen, macrofossils like fruits, seeds, wood and charcoal) and palaeozoological (Cladocera, bone remains from archaeological contexts) was performed. The profile of organic sediments of palaeochannel fillings has been collected and palaeoecological analyses of sediments have been elaborated as well. Both sites have been situated on sandy ground, one of them (site no. 53) on deluvial sediments, and the second (site no. 56) on river terrace and slope of the Narew River valley. The settlement complex has b...

The _ Zabieniec kettle hole is the first peatland in central Poland analyzed quantitatively with four biotic proxies (plant macrofossils, pollen, testate amoebae and chironomids) to reconstruct the past environmental change. Palaeoecological data were supported by historical and archaeological records. We focused on autogenic vegetation change and human impact in relation to climatic effects. The aims of our study were (a) to describe the development history of the mire during the last 2,000 years, (b) to date and reconstruct the anthropogenic land-use changes and (c) to discuss a possible climatic signal in the peat archive. The combination of proxies revealed dramatic shifts that took place in the peatland since the Roman Period.

Background: Few studies on eurypterids have taken into account morphological changes that occur throughout postembryonic development. Here two species of eurypterid are described from the Pragian Beartooth Butte Formation of Cottonwood Canyon in Wyoming and included in a phylogenetic analysis. Both species comprise individuals from a number of instars, and this allows for changes that occur throughout their ontogeny to be documented, and how ontogenetically variable characters can influence phylogenetic analysis to be tested. Results: The two species of eurypterid are described as Jaekelopterus howelli (Kjellesvig-Waering and St˘rmer, 1952) and Strobilopterus proteus sp. nov. Phylogenetic analysis places them within the Pterygotidae and Strobilopteridae respectively, both families within the Eurypterina. Jaekelopterus howelli shows positive allometry of the cheliceral denticles throughout ontogeny, while a number of characteristics including prosomal appendage length, carapace shape, lateral eye position, and relative breadth all vary during the growth of Strobilopterus proteus. Conclusions: The ontogeny of Strobilopterus proteus shares much in common with that of modern xiphosurans, however certain characteristics including apparent true direct development suggest a closer affinity to arachnids. The ontogenetic development of the genital appendage also supports the hypothesis that the structure is homologous to the endopods of the trunk limbs of other arthropods. Including earlier instars in the phylogenetic analysis is shown to destabilise the retrieved topology. Therefore, coding juveniles as individual taxa in an analysis is shown to be actively detrimental and alternative ways of coding ontogenetic data into phylogenetic analyses should be explored.

The origin and composition of the turtle shell has consistently been studied by both palaeontologists and neontologists, with most of the research focused on homologies and morphogenesis of costals, neurals and (lately) the nuchal bone. The generally poorly visible shell sutures in pre-Jurassic turtles have resulted in poor understanding of the initial layout and number of shell bones. The aim of the present study is to fill this gap by examination of the shell structure in the oldest fully-shelled turtle, the Norian Proterochersis from Germany and Poland. This taxon is of critical significance to the understanding of turtle phylogeny, not only for stratigraphic reasons, but also because of its controversial position in the phylogenetic tree of turtles (i.e., either as the basalmost pleurodire, or a stem turtle). The new material from Poland and some historical German specimens have enabled identification of new shell characters. An osseous contact between the sacral vertebra and carapace exists, and all ten pairs of thoracic ribs contribute to the shell, the first pair not being reduced, roughly parallel to the second and forming costal plates. These characters are unique to Proterochersis and may represent the ancestral condition of the turtle shell; therefore they should be considered in future work on the origin and early evolution of the turtle bauplan. An updated scenario of early shell evolution may be provided. The presence of well-developed, costal plate-bearing first thoracic ribs in Proterochersis may have implications for the recently resurrected hypothesis of a turtle-Eunotosaurus affinity.
