The Caradocian (Ordovician)-Wenlock (Silurian) Takche Formation of the Spiti region, northwestern Himalaya, is a highly fossiliferous litho-unit which has yielded bryozoans, coral reefs,
conodonts, algae, ostracods and trilobites (Hayden 1904; Reed 1912; Bhargava & Bassi 1986, 1998; Suttner 2003, 2007).
Conodonts and fish remains from the Stonehouse Formation, Arisaig, Nova Scotia.
Long-term cycles of Triassic climate change: a new d18O record from
conodont apatite.
As is commonly the case with Pennsylvanian
conodont studies, Pa elements of Idiognathodus dominate the collection.
Conodont elements known to be related to the Triassic age would be as follows: Prioniodella Prioniodellides, Hindeodella multihamata, Hindeodella nevadensis, Lonchodina nevadensis, Hindeodella triassica, Ligonodina triassica, Diplodella lautissima, Pachycladina oblique, Hadrodontina anceps, Ellisonia triassica, hibardella subsymmertica, Parachirognathus geiseri, Prioniodella decrescens, Enantiognathus bitortus, Chirognathus sp., Xaniognathus sp., and Anchiognathudos sp.
307) regarded the Castell Limestone
conodont fauna to be of early A.
As with other geological systems, Permian
conodont distribution has been influenced by facies differences.
Last year, scientists at Leicester University in England demonstrated that enigmatic fossils known as
conodonts in fact represent the earliest known vertebrates.
Through the climatic changes,
conodont and ammonoid faunae were initially able to recover very quickly during the Early Triassic as unusually short-lived species emerged.
In recent years he has discovered hundreds of complete
conodont mouth apparatuses in 425-million-year-old lagoons on the Bruce Peninsula.
Stratigraphy and
conodont faunas of the Maxville Group (Middle and Upper Mississippian) of Ohio.
The Viki section was selected as a basis for deriving ID numbers because of the great thickness of the Telychian, large number of bentonites, and a well-established
conodont biostratigraphy (Jeppsson & Mannik 1993; Kiipli et al.
III (1976) The Stratigraphy, Sedimentary, and
Conodont Paleoecology of the Floyds Knob Bed and Edwardsville Member of the Muldraugh Formation (Valmeyeran), Southern Indiana and North-central Kentucky.
Extremely common in rocks from 520 to 205 million years old, the pointy, millimeter-sized
conodont fossils have mystified paleontologists for 150 years.
