| Abstract: | New specimens of hyaenodontid creodonts are described which were unearthed in Mongolia by the Austrian–Mongolian Paleontological expeditions. Five taxa are identified: Hyaenodon eminus, Hyaenodon pervagus, Hyaenodon cf. incertus, Hyaenodon cf. mongoliensis, and cf. Hyaenodon gigas. Hitherto unknown morphological details are reported for most of these species. The implications to systematic of the species and the genus Hyaenodon are discussed. These Hyaenodon remains suggest a separate evolutionary lineage, with different species in Europe and Asia, even if the genus is also known from contemporary faunas of Europe and North America. |
