| INFO |
Allosaurus (Marsh, 1877) Creosaurus atrox (Marsh,1878) Epanterias amplexus (Cope,1878) Labrosaurus (Marsh,1879) Saurophagus (Ray,1941) Allosaurus > A. fragilis (Marsh,1877) >> Poekilopleuron valens (Leidy,1870) Laelaps trihedrodon (Cope,1877) Creosaurus atrox (Marsh,1878) Epanteris amplexus (Cope,1878) Hypsirophus discurus [partim] (Cope,1878) Allosaurus lucaris (Marsh,1878) Allosaurus ferox (Marsh,1896) ?Saurophagus maximus (Ray,1941) ?Labrosaurus ferox (Marsh,1884) Camptosaurus amplus (Marsh,1879) = Camptonotus amplus (Marsh,1879) A. whitei (Pickering, 1995) Allosaurus > A.tendagurensis (Janensch,1925) Based on a few skull elements, hyoid, vertebral fragments, a supposed sternum which is lost, ilium, astragalus and pedal fragments. The jugal shows an A. fragilis-like ventral deflection,but the ilium has an Allosaurus. sp. nov.-like vertical ridge. Generally treated as a junior synonym of Allosaurus fragilis, the form is considered a distinct species (A. atrox), and possibly a definable genus by a few researchers. |
