New Late Cretaceous mammals of southern Kazakhstan
Aleksander O. Averianov
Mammalian remains from the lower part of the Darbasa Formation (lower Campanian) at the `Grey Mesa' locality in the Alymtau Range, southern Kazakhstan, are described. They include ?Bulganbaatar sp. (Multituberculata), Deltatheridium nessovi, sp. n. (Deltatheroida), and four eutherians: an undeterminated ?otlestid kennalestoid (?Otlestidae), ?Alymlestes sp. (Zalambdalestidae), ?Aspanlestes sp. (Zhelestidae), and an undeterminated eutherian. This new Cretaceous fauna is most similar to that from the Djadokhta Formation in Mongolia and may tentatively confirm an early Campanian age for the latter.
Key words: Mammalia, Cretaceous, Kazakhstan, Mongolia.
