There are three sections: (1) Topographical Location of the selected sites, in terms of UTM coordinates and heights (m), above the present medium sea level (a.p.s.l.); (2) Geology and Radiometric ages, including a short geological description of the marine deposits, their radiometric ages and dating methods; (3) Paleontology and Paleoclimate, with a summary of the main fossil fauna, species and/or subspecies, collected from the sites and properly classified in accordance with the Systematic Paleontology; and an interpretation of the paleoclimatic conditions at the time the fossils lived and were deposited. Moreover, when available, values of SST (Sea Surface Temperature) have been also calculated (or estimated). Each section is presented with their available scientific source(s).

However, there are records of organisms with stromatoporoid-type structure in Carboniferous strata, the subject of this study. The Viséan fossil Labechia carbonaria Smith 1932 has been discussed previously in literature and its affinity has not been confirmed. In this study, the type material of L. carbonaria collected from the middle part of the Frizington Limestone Formation (previously called Seventh Limestone), Holkerian Substage, stored in the Natural History Museum (London, UK) and British Geological Survey (Keyworth, UK) was re-examined. The Holkerian Substage, in which L. carbonaria was found, lies between ca 335–339 Ma, and the Frizington Limestone Formation ranges from topmost Arundian to upper Holkerian, so middle Frizington Limestone Formation is likely approximately 337 Ma. L. carbonaria comprises thick long ...

These unequivocal structures appear in several specimens coming from different sites. Their preservation varies from a gastric cavity with muscle bundles in some individuals to only longitudinal muscle bundles in others. The muscle bundles fuse apically or medially, normally forming V-shaped pairs, and they extend along the theca/exoskeleton, parallel to the corner, towards the aperture. Longitudinal bundles have predominant perradial positions. Although there have been some articles on conulariid soft parts, most of them refer to relic soft parts. This is the first time that these structures are shown using µCT. Discovery of conulariid soft parts contributes to knowledge of metazoan evolutio...

The eastern Canary Islands have geographic and geological conditions derived from the movements of the Central American plates. Some features of these islands are influenced by the rotation of the Earth from west to east in the evolution of the marine currents that surround them and the opening of the North Atlantic to the North Pole with little dependence of the glacial isostatic adjustment (GIA). In addition, their position with respect to the Tropic of Cancer and the African continent affect the north-south and east-west climatic change dynamics and their tectonic stability respectively. Dated lavas contain marine and aeolian deposits and some of the Pleistocene marine deposits indicate higher sea level in cooler circumstances, which is anomalous. Relating those marine deposits produced during the warmest interglacial, the last interglacial and the Holocene with their equivalents in the Southern Hemisphere, they reflect shifts in the barycentre. Thanks to Holocene radiocarbon, topographic and day length data and alkenone temperature, we describe a mechanism by which the oscillation of the Moon's inclination (and declination) reaches extreme values (14˚ and 34˚; about 4.9˚ more than current values) approximately every 1450 years. These values occur when there is a harmonic distortion in surface areas of the Earth's crust as response associated with oscillations in the displacements of the barycentre of the Earth-Moon How to cite this paper:

Reports of their occurrence are fundamental and far-reaching for understanding microfacies and diagenesis where they occur; and fossil biotic assemblages, as well as wider aspects of origins of animals, sponge evolution/ecology and the systemic recovery from mass extinctions. Keratose sponges: 1) have elaborate spongin skeletons but no spicules, thus lack mineral parts and therefore have poor preservation potential so that determining their presence in rocks requires interpretation; and 2) are presented in publications as interpreted fossil structures almost entirely in two-dimensional (thin section) studies, where structures claimed as sponges comprise diverse layered, network, particulate and amalgamated fabrics involving...

This collection started to be built with the first fossil sponges from the Cretaceous of Wiltshire, collected by William Smith in 1816 and 1818 for the first geological map of England. The latest specimen to enter the collection was collected from the Permo-Carboniferous of Norway by Angela Milner, a researcher at the Museum, in 2000. Although they are mostly from the Cretaceous of England, lithistids are represented from the Cambrian to Cenozoic of England. This makes this collection key for studying this group. Lithistid study will help with understanding of biosilicification evolution in sponges to unlock the changing patterns in the silica cycle in the oceans through geological time. A dataset with information about all the Fossil Lithistida Collection is available through the NHM Data Portal and Suppl. material 1. This dataset includes taxonomic...

Determinations of 753 out of 1131 specimens in the collection have been revised and all associated information has been catalogued. We conclude that this is the most important collection of conulariids, scyphozoan cnidarians with conical, phosphatic skeletons, in the world.

There are three sections: (1) Topographical location of the selected sites, in terms of UTM coordinates and heights (m), above present sea level (APSL); (2) geology and radiometric ages, including a short geological description of the marine deposits, their radiometric ages and dating methods; (3) paleontology and paleoclimate, with a summary of the main fossil fauna, species and/or subspecies, collected from the sites and properly classified in accordance with the systematic paleontology; and an interpretation of the paleoclimatic conditions at the time the fossils lived and were deposited. Moreover, when available, values of SST (Sea Surface Temperature) have been also calculated (or estimated). Each section is presented with their available scientific source(s).
