About 50 years ago, Jean Brunet, who was studying Equus and Hipparion, took photographs of some British equids, in particular of Hipparion teeth from the Red Crag, Suffolk and left them to me. Some of the teeth were illustrated and discussed by Pirlot (1956).
Metapodials of H. crassum have large epiphyses (in particular the distal articular width) but not so « robust » diaphyses. In Eurasia, there is only one MC close to the typical H. crassum : it comes from a Mongolian locality (Kirgiz-Nur 51-55, PIN 3222-433).
MT of Montmartel and Chabeuil (France), possibly a fragment from Apolokkia (Greece) probably belong to H. crassum, as well as the MT
of Ercsi (see Kislang) although it is bigger.
There are other metapodials in Eurasia differing from H. crassum by a larger size and/or very developed distal supra-articular tuberosities. The MC come from Le Soler (Spain), Eupatoria (Crimea), Çalta (Turkey), and Mongolia (H. tchicoicum from Shamar, Beregovaja ; H. cf. tchicoicum from Kolu ? or Kirgiz-Nur ?) ; possibly a few badly preserved fragments from Ptolemais (Greece). The MT come also from Le Soler, Çalta, Mongolia, and from Romania (Iaras, Malusteni).
