New materials of Exallerix pustulatus (Erinaceidae, Eulipotyphla) from Nei Mongol and other Brachyericinae of China
Abstrak
This article describes new fossil material of Exallerix pustulatus from the early Late Oligocene of Nei Mongol, China. The specimens supplement and clarify certain mandibular and lower dental morphological features of this species, allowing for further comparisons with other short-faced hedgehogs. Previously, E. pustulatus had only been recorded from the Hsanda Gol Formation at Taatsiin Gol, in the Valley of Lakes, Mongolia. This discovery of new material from Sonid Left Banner marks the first occurrence of the genus Exallerix in China. In addition, discussions of other short-faced hedgehog fossils from Chinese localities confirm the validity of Metexallerix gaolanshanensis, which lived during the late Late Oligocene, approximately 25 Ma. Furthermore, the short-faced hedgehog specimens from locality Damiao 16 in Nei Mongol are tentatively referred to Synexallerix junggarensis, rather than M. gaolanshanensis.
