| Abstract: | Seven hitherto unpublished Dorcatherium guntianum teeth from the Early Miocene of Germany are described. Morphology and size of the teeth are documented in detail and taxonomic affiliation is assessed based on comparisons to type materials of European tragulids. The fossils represent one of the earliest European Dorcatherium records and the oldest unequivocal evidence of D. guntianum from Germany. A review of the European Dorcatherium occurrence pattern suggests that a bunoselenodont and a selenodont lineage immigrated into Europe simultaneously from the East or Southeast, and corroborates the interpretation of the genus as being diphyletic. Moreover, our data add support to immigration scenarios that have been linked with the emerging freshwater wetlands, which formed as a result of the regression in the Western Paratethys. |
