About Pseudamphimeryx

Pseudamphimeryx is an extinct genus of Palaeogene artiodactyls belonging to the Amphimerycidae that was endemic to the central region of western Europe and lived from the Middle to Late Eocene. It was first erected in 1910 by the Swiss palaeontologist Hans Georg Stehlin, who assigned to it multiple species and noted specific differences from another amphimerycid, Amphimeryx. As of present, it is known by six species, although the validity of P. valdensis has been questioned while the earliest-appearing species P. schosseri has been suggested to not be an amphimerycid.

Pseudamphimeryx is very similar to Amphimeryx with its selenodont (crescent-like ridges) dentition and its fused "cubonavicular bone" (cuboid bone and navicular bone) of its hind legs, both of which are recorded in ruminants in an instance of parallel evolution. Both amphimerycid genera had large orbits and long snouts. Pseudamphimeryx has very specific differences with Amphimeryx such as the occipital crest forms. Its selenodont dentition suggests that it had a preference for leaf-eating diets. Pseudamphimeryx was a tiny-sized artiodactyl that likely weighed less than 1 kg (2.2 lb).
