Chalicomys is an extinct genus of castorid rodent that lived during the Miocene epoch.[1] Its fossils have been found in Europe, from Spain to Poland.[2]
Description
The mandibular fourth premolar of Chalicomys jaegeri is characterised by all flexids being orientated diagonally on the occlusal surface, with a paraflexid that is slightly longer than the metaflexid and that opens mesially and lingually. On the maxillary fourth premolar, the parafossette has the shape of a hook and is partially parallel to the hypoflexus on the occlusal surface.[3]
