Spanning 1.5 meters in length,
Hyrachyus was related to
palaeotheres. Physically, it would have looked very similar to modern
tapirs, although it probably lacked the tapir's characteristic
proboscis. Its teeth, however, resembled those of a rhinoceros, supporting the idea of its relationship with that group. It is proposed by some that
Hyrachyus (or a hyrachyid of similar form) served as a common ancestor for North American rhinoceratoids. ==References==
