Dental anomaly in a middle Miocene fossil of the genus Spermophilinus (Rodentia, Sciuridae) from southern Germany

Abstract

The maxillary presented in this work has been excavated in the middle Miocene karst filling Petersbuch 136 (Germany, Bavaria) and shows the oldest evidence of dental anomaly in a sciurid. The aberrant morphology, probably hyperdontia or no replacement of roots of deciduous teeth, affects the area of the P3, a tooth that is generally not well documented in the Spermophilinus record.

Key words

Bavaria, Miocene, Frankonian Jura, squirrel, tooth anomaly, P3
