Mammalia - Perissodactyla - Palaeotheriidae

Diagnosis: Small palaeotheriid Equoidea, with an estimated P2/-M3/ length of about 40 mm, a buno-lophodont and brachydont dentition, an occasional mesostyle and a parastyle not very protruding on upper molars, a protocone mesially shifted on P4/, a distal expansion of the postero-lingual cingulum on P3/ P4/, and narrow lower molars with thick and continuous labial cingulids. Differs from species of Pachynolophus in having a wider P2/ and an occasional mesostyle on upper molars. Further differs from more advanced Palaeotheriidae (Lophiotherium, propalaeotheres, and Palaeotheriinae) in possessing an inconstant mesostyle on upper molars, a parastyle less protruding and a shallower protoloph groove on upper molars, a lingual cingulum on these teeth stronger than in most of them, a P4/ triangular (instead of being subquadrangular), and a hypoconulid more developed on M/1-M/2.
