Taxon Status | ACTIVE |
Comments | The active definition is a first-order revision of the definition first proposed by Sereno (1998) and uses species as specifiers. The taxon tentatively includes two or three genera (Camptosaurus, Cumnoria, Callovosaurus), one of which (Camptosaurus) includes several species (Norman 2004). The taxon is often erroneously attributed to Marsh (1889) or Marsh (1895). |
