5 individuals, including nearly complete adult skeleton.
Ceratosaurus nasicornis is diagnosed by its median nasal
"horn" fusion between metatarsals II-IV, and epaxial osteoderms
(Gilmore, 1920). A nasal horn also occurs in Proceratosaurus
bradleyi, but the latter taxon bears a large, circular
maxillary fenestra and an antorbital maxillary tooth row, diagnostic
characters of Tetanurae
(Gauthier, 1986), and it lacks the diagnostic characters of Ceratosauria.
