The purpose of this application, under Article 75.5 of the Code, is to conserve the usage of the name Allosaurus Marsh, 1877 by replacement of the fragmentary and nondiagnostic holotype of Allosaurus fragilis Marsh, 1877 with a diagnostic skull and skeleton from the same quarry. The name of the genus Allosaurus, whose type species is A. fragilis, is widely accepted by palaeontologists and has been familiar to the public for decades and it is essential that an adequate type be available. It is proposed that all type species fixations for the genus Allosaurus be set aside and a neotype be designated.
