|---|---|---|
| D. Geraads et al. 2008 | A primitive hippotragine of medium size, with a braincase slightly inclined on the splanchnocranium and broad over the mastoids, both halves of occipital surface facing partly laterally, a basioccipital with strong anterior tuberosities not reaching the level of the foramen ovale, large orbits with very prominent rims, a short face with a small jugal and a short and deep lacrimal bone, a large diffuse ante-orbital fossa, a relatively large ethmoidal fissure, premaxillae not contacting nasals, long slender curved horn-cores with some sigmoid curvature in antero-dorsal view, usually without transverse ridges, uprightly inserted and close to the midline, a large sinus in the pedicle, rather small supraorbital foramina, molar pattern simpler than in modern hippotragines, and premolars neither shortened nor enlarged. |
