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]
The 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]
The 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.
