NEW PALAEORYCTIDAE (MAMMALIA) FROM THE EOCENE OF KYRGYZSTAN AND MONGOLIA

Abstract

Two new palaeoryctids from the Eocene Asiatic genus Nuryctes are described. N. alayensis sp. nov. (terminal Lower Eocene, Alai Beds, Andarak 2 locality, Kyrgyzstan) is more primitive in the extent of premolar reduction than the type species N. qinlingensis (Tong, 1997) from the Middle Eocene of China. N. gobiensis sp. nov. (Middle Eocene, Khaychin Formation, Khaychin-Ula 2, Mongolia) is more advanced in the structure of check teeth than the other two species.
