Abstract

"Age assessment of late Tertiary rocks north of the Altai Mountains, Mongolian People's Republic, is refined by renewed study of a small collection of mammalian fossils made by the Central Asiatic Expedition in 1925. A dentary fragment with P[subscript 3] assignable to Trischizolagus most closely resembles an early Pliocene member of the genus from Afghanistan. Trischizolagus is also known from late Miocene and Pliocene deposits of Spain, France, Romania, and Greece. An equid, formerly considered as Equus and an indicator of Pleistocene age, is a hipparionine referable to 'Hipparion' houfenense. Other elements of the fauna are 'Oioceros' sp., a proboscidean possibly representing Sinomastodon, and a rhinocerotid resembling Chinese Chilotherium. All are comparable to late Tertiary taxa known from elsewhere and suggest an age for the sediments near the Miocene-Pliocene epoch limit"--P. [1].
