The International Commission on Zoological Nomenclature has used its plenary power to conserve the usage of the name Allosaurus Marsh, 1877, by designating specimen USNM 4734 as the neotype to replace the nondiagnostic holotype (YPM 1930) of Allosaurus fragilis Marsh, 1877. In their comment supporting Case 3506, Loewen & Chure (2010) specified the skeletal elements (attributable to a single individual) that should constitute the neotype.
