Allacerops is an extinct genus of odd-toed ungulate belong to the rhinoceros-like family Eggysodontidae. It was a small, ground-dwelling browser, and fossils have been found in Oligocene deposits throughout Central and East Asia.
Allacerops was synonymized with Eggysodon by Heissig (1989), but is now considered a distinct genus.[1][2][3][4] Unaware that Wood (1932) made turgaica the type species of Allacerops, Reshetov et al. (1993) erected Tenisia for "Epiaceratherium" turgaica. Tenisia, however, was already in use for a brachiopod, so Spassov (1994) erected Teniseggysodon as a replacement. In any case, Qiu et al. (1999) recognized Teniseggysodon a junior objective synonym of Allacerops as both were based on the same type species.[5][6][7]
