Rapid warming at the beginning of the Eocene (the Initial Eocene Thermal Maximum, or IETM) has been associated with modest changes in floral composition, mostly shifts in the relative abundances of taxa rather than large numbers of first or last appearances. Although floral change across the Paleocene-Eocene transition has been studied in many areas, few fossils demonstrably come from the ∼200 ...

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...
