Lycorhinus is a genus of heterodontosaurid ornithischian dinosaur that lived during the Early Jurassic, in the Sinemurian. It is known from a single species L. angustidens, that was named in 1924 by Sidney H. Haughton as a cynodont for a partial jaw found in the Upper Elliot Formation of South Africa. The genus name is derived from the Ancient Greek words for "wolf" and "nose". The limited material available, which has degraded over time to only be represented now by a single original tooth and the impression of the remaining jaw and teeth, has resulted in multiple different interpretations of the diagnostic nature and synonymy of Lycorhinus, including the treatmens of the type species of Heterodontosaurus, Abrictosaurus, and Lanasaurus as either species of Lycorhinus or synonyms. The latest review of Lycorhinus accepted the synonymy of Lanasaurus scalpridens, named in 1975 by Christopher Gow for a maxilla from Golden Gate Highlands National Park, with Lycorhinus angustidens, and also the referral of a partial skull found at the same locality as the original holotype decades later. Tentative specimens from the Clarens Formation have also been considered allied with Lycorhinus, but they may be better treated as remains of indeterminate heterodontosaurids.
