摘要

We described a new pair of incomplete mandibles from the Qingshuiying locality, Northwest China, and referred it to Eggysodon, E. lingwuensis sp. nov. The new species has a typical mosaic assemblage of features: dp1 (or p1) is present at adult stage, but the symphysis is posteriorly elongated and the diastema distance between the canine and dp1 (or p1) is further shortened. In terms of the evolutionary stage, E. lingwuensis sp. nov. is more advanced than E. osborni, but comparable to that of E. gaudryi. Together with other mammals from the Qingshuiying locality, we suggested that the strata-produced new material was deposited during the Early Oligocene. On the other hand, the continental fauna exchange during the Palaeogene between Europe and Asia had very scarce records. Eggysodon has four species from the Oligocene of Europe. This record definitely confirmed that there is a migration route between Central Europe and East Asia during the Early Oligocene.
