Chalicomys is an extinct genus of castorid rodent that lived during the Miocene epoch. Its fossils have been found in Europe, from Spain to Poland.
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.
