Revision of annulated orthoceridan cephalopods of the Baltoscandic Ordovician
The annulated orthoceridans of the Middle and Late Ordovician of Baltoscandia are described and their systematic frame is revised. The revision of these nautiloids, which are part of the Orthocerida and Pseudorthocerida, is based on the investigation of characters of the septal neck, the siphuncular tube, and the apex. An unequivocal terminology of these characters is suggested and applied. The...
متن کاملPalaeogeography and palaeoecology of early Floian (Early Ordovician) cephalopods from the Upper Fezouata Formation, AntiAtlas, Morocco
This is the first description of Ordovician cephalopods from Morocco. Although their occurrence has been known for a long time, only a poorly preserved conch from the late Katian of Ikhf n’Ouzerg (central Anti-Atlas) was described as “Orthoceras hastile Barrande” by Termier & Termier (1950). In some cases Ordovician cephalopods were mentioned within faunal lists without classification (e.g., Gu...
متن کاملPaleontology: A New Burgess Shale Fauna
A spectacular Cambrian soft bodied fauna some 40 km from Walcott's original Burgess Shale locality includes over 50 taxa, some 20% new to science. New anatomical evidence from this site will illuminate the evolution of early marine animals.
متن کاملReview and palaeoecological analysis of the late Tremadocian – early Floian (Early Ordovician) cephalopod fauna of the Montagne Noire, France
By comparison with the relatively diverse Early Ordovician cephalopod faunas that lived in association with the low latitude carbonate platforms (e.g. Laurentia [Flower 1964]; Siberia [Balashov 1961]; China [Chen 1976]), those of the high latitude margins of Gondwana are of relatively low diversity, generally poorly known, and where known, often in need of revision. Of those high latitudinal as...
متن کاملMammals from the Blue Ash Local Fauna (late Oligocene), South Dakota. Rodentia, Part 4: Family Aplodontidae
Ten species of aplodontid rodents are present in the Blue Ash local fauna, which currently represents the most diverse family of rodents in the assemblage. One new genus, Disallomys, is described with Allomys storeri Tedrow and Korth as the type species. Four new species are described, Disallomys robustus, D. intermedius, Prosciurus clausulus, and Niglarodon brachyodon. The aplodontids from the...
