N2 - 2014AbstractFour recently collected mammal specimens from the Upper Cretaceous (Santonian–?Campanian) Bostobe Formation in the northeastern Aral SeaRegion, Kazakhstan are attributed to Asioryctitheria indet. (an edentulous dentary fragment) and the zhelestid Parazhelestes sp. cf. P. mynbulakensis(a maxillary fragment with a double-rooted canine, an M1, and a dentary fragment including m3). These new records double the known mammalfauna from this formation, which previously included the zhelestid Zhalmouzia bazhanovi and Zhelestidae indet. The taxonomic and ecologicalstructure of the mammal assemblage from the Bostobe Formation can, on present evidence, be considered close to the other eutherian dominatedLate Cretaceous mammal assemblages of Central Asia. This region is important in particular in the search for Late Cretaceous ancestors ofcrown-group eutherian mammal clades (Placentalia).
