Eggysodontidae is a family of perissodactyls, closely related to rhinoceroses. Fossils have been found in Oligocene deposits in Europe, the Caucasus, Central Asia, China, and Mongolia.[1]

Taxonomy
editThe family Eggysodontidae has been at times considered a subfamily of Hyracodontidae, as Eggysodontinae, by several authors.[2][3][4][5] However, recent analyses have leaned towards recognizing eggysodonts as a distinct family more closely related to crown Rhinocerotoidea than to hyracodonts or paraceratheres.[6][7][8]
Biology
editEggysodonts were ground-dwelling browsers, being largely the size of dogs.
