It lived during the Early Cretaceous (Valanginian to Barremian stages) around 145-136 million years ago. Its fossils were found in the Woburn Sands Formation of England. Craterosaurus may actually be a junior synonym of Regnosaurus, but only one fossil, a partial vertebra, was recovered. The type (and only known) species is Craterosaurus pottonensis, described in 1874 by Harry Seeley.[1] The specific name refers to the Potton bonebed. Seeley mistook the fossil, holotype SMC B.28814, for the base of a cranium. Franz Nopcsa in 1912 correctly identified it as the front part of a neural arch.[2] Craterosaurus was placed in Stegosauria by Galton,[3] although subsequent authors did not recognize Craterosaurus as a distinct, valid taxon.[4][5] See also{{Portal|Dinosaurs|Cretaceous|Prehistory of Europe}}
