Deperetella is an extinct genus of deperetellid perissodactyls from Middle to Late Eocene of Asia.[2] The genus was defined in 1925 by W. D. Matthew and Walter W. Granger, who named it after French paleontologist Charles Depéret.[3] The type species is Deperetella cristata.[4][2]

Description
editThe front-root teeth (premolars) are longer than the posterior-root teeth (molars), there are well-developed hypolophides on P3-P4, and the forelimbs are three-toed. It differs from Teleolophus in the size of the molars.[4][2] Postcranial skeleton of Deperetella shares many similarities with that of Teleolophus, in particular: long and slender limbs, relatively elongated and narrow lunar with a slightly concave medial edge of the radial facet, fibula reduced or fused with the tibia, three functional fingers on the limbs.[5]
Taxonomy
editThe genus Diplolophodon, erected by Zdansky (1930) based on an upper dentition from the Heti Formation, China, was defined by Radinsky (1965) as a junior synonym of Deperetella.[2] In Reshetov and Tatarinov (1979),[4] Tsubamoto et al. (2000)[2] and later works Diplolophodon is also considered as a synonym of Deperetella.[6] However, it recovered as a valid genus in Deperetellidae family in a work of Bai Bin (2023).[6] The species Deperetella birmanica from Myanmar was assigned to the new genus Bahinolophus in 2005.[6]
