Fraserosphenodon is an extinct genus of sphenodontian - the same group to which the tuatara belongs - found in the Late Triassic of the United Kingdom.
This genus contains a single species, Fraserosphenodon latidens.. It was found by Nicholas C. Fraser, the Scottish palaeontologist and current Keeper of Natural Sciences at National Museums Scotland, and named in his honour. Originally, this taxon was assigned to Clevosaurus latidens Fraser, N.C., 1993, A new sphenodontian from the early Mesozoic of England and North America: Implications for correlating early Mesozoic continental deposits, in Lucas, S.G., and Morales, M., eds., The Nonmarine Triassic: New Mexico Museum of Natural History and Science Bulletin, v. 3, p. 135–139, but it was later re-assessed and found to sit outside of this genus, and so was renamed.
