摘要	We place on the record a newly discovered amphicyonid (beardogs) upper molar from the Early Miocene Lower Red Mudstone Member of Aoerban Formation in central Nei Mongol. This molar is highly diagnostic of European haplocyonine or North American temnocyonine, two subfamilies of beardogs that have long been known in those continents but notably absent in Asia. The new molar is strikingly similar to Haplocyonoides mordax and Temnocyon percussor with its dumbbell-shaped M1 outline, reduced parastyle, isolated protocone by a surrounding cingulum, and extreme reduction of pre- and postprotocristae. Given the limited material at hand, we tentatively refer the new Chinese fossil to the European Haplocyonoides cf. H. mordax because of their similar size and age relationship. If this identification is correct, our new record thus fills a large gap in the geographic distribution of the haplocyonines and represents an excursion of this rare subfamily from Europe.
