Lycorhinus is a genus of heterodontosaurid ornithischian dinosaur hailing from the Early Jurassic ( Hettangian to Sinemurian ages) strata of the Elliot Formation located in the Cape Province, South Africa.
The fossil material consists of dentaries and maxillae, hence the characters mentioned by the name Lycorhinus angustidens that Sidney H. Haughton attributed to the remains in 1924, where the generic name means " wolf snout", as it was at first misidentified as a cynodont, and the specific descriptor means "constricted tooth".
The holotype, SAM 3606, consists of a mandible found by Dr M. Ricono. Three other species of Lycorhinus have been named. Lycorhinus parvidens was created by Robert Broom and Lycorhinus tucki by Richard Anthony Thulborn in 1970 renaming Heterodontosaurus tucki, but these have failed to find recognition. Lycorhinus consors, named by Thulborn in 1974, was renamed Abrictosaurus by James Hopson in 1975.
Lycorhinus, including the remains described by Gow in 1975 as Lanasaurus, is a small ( in length) herbivorous dinosaur despite the long canines it sported in its jaws; in view of this typical characteristic L. angustidens is very clearly allied to Heterodontosaurus. Only in 1962 Alfred Walter Crompton recognised it was an ornithischian dinosaur. Thulborn in 1971 created a separate Lycorhinidae but this group was in 1972 equated with Heterodontosauridae by Peter Galton.
