Data: | 2011 |
Resum: | The finds of Miocene beavers are not rare at all. Neverthe− less, in most localities these rodents are only represented by a few dental elements, so that large collections are only occa− sionally available to researchers. Hence, the description of sufficiently large samples, such as the recently published de− scription of Steneofiber depereti from Hambach 6C (NW Germany, MN5) by Mörs and Stefen (2010), deserves the greatest attention. After a comprehensive description and comparison of the material, these authors conclude that pre− vious citations of the beaver Chalicomys jaegeri from the MN4 to MN6 (early to middle Miocene) are misidentifica− tions of the genus Steneofiber. Following Stefen (2009), these authors further question the validity of all the known Chali− comys species from the later middle Miocene (MN7+8). We agree with these authors that the occurrence of C. jaegeri in the middle Miocene is doubtful, but we disagree with their arguments for the synonymization of several species. Here we address this point and discuss the taxonomic criteria for distinguishing both genera, further reviewing the taxonomy of the genus Chalicomys at the species level. |
