RESULTS

As expected, E. ovodovi crania do not resemble E. hydruntinus nor any extant species ( Eisenmann 2022: figs 28, 42) though such narrow supra-occipital crests occur in extant and fossil horses ( Eisenmann 2022: figs 58, 62).

From E.hydruntinus they differ mainly ( Table 1 View TABLE ) by the smaller breadth of their supra-occipital crest (measure 16), their longer muzzle (measure 5)and their relatively narrow choanae (measure 10).

Surprisingly, they are rather similar to the Early Pleistocene E.vekuae Eisenmann,2022 from Dmanisi ( Eisenmann2022: 57) apart from their relatively shorter post-vomerine length (measure 4) and their relatively deeper naso-incisival notch (measure 32).

The teeth are similar to that of the E. ovodovi type and other specimens from Proskuriakova, and differ from E. hydruntinus by longer protocones ( Eisenmann & Vasiliev 2011).
