The Paleocene-Eocene Thermal Maximum (PETM) is associated with major extinctions in the deep ocean, and significant paleogeographic ecological changes surface ocean terrestrial environments. However, impact of environmental change on shelf biota less well understood. Here, we present a new PETM record low paleolatitude shallow-marine carbonate platform from Meghalaya, NE India (eastern Tethys)....

More than 50 specimens of fossil crabs collected from the Cannonball formation (Paleocene) of southern Morton and Burleigh Counties, south-central North Dakota form the basis for the first report of fossil crustaceans in North Dakota. The new genus Camarocarcinus is created for their reception with the new species C. arnesoni as the type species. A separate, single, large propodus is placed in ...

The record of extinct African metatherians (Mammalia, Theria) is scanty, restricted in time (Eocene–Miocene), and its taxonomy still subject debate. A review all metatherians, or alleged known up to now, led us the recognition only three taxa referable this group: (1)  Kasserinotherium tunisiense  (Peradectoidea?), from early Eocene Tunisia; (2)  Peratherium africanum &nbsp...

The Cretaceous-Paleogene boundary marks a critical event in mammalian evolution. Using a database of 4769 mammalian specimens from the Hell Creek and lower Fort Union formations of Garfi eld County, northeastern Montana, I quantifi ed temporal patterns of diversity and community structure to evaluate faunal dynamics during the last ~1.9 m.y. of the Cretaceous, the Cretaceous-Paleogene extinctio...
