[D] Dryptosaurus potens
Describer
Gilmore, 1921
Time
Cretaceous Early Hauterivian Barremian
Classification
Saurischia Theropoda Incertae Sedis \\\"Carnosaurs\\\" Nomina Dubia
Diet
Carnivore
Fossilsite
Arundel Formation, Potomac Group, Maryland, US
Info
\\\"Capitalsaurus\\\" (Kranz, 1998) \\\"Capitalsaurus\\\" potens (Lull, 1911) = Creosaurus potens (Lull, 1911) = Dryptosaurus potens (Gilmore, 1921)
Vertebrae.
Lull (1911) described Creosaurus potens, on the basis of a vertebral centrum (USNM 3049) which was larger than those assigned to Allosaurus medius and described it as a caudal dorsal vertebra, but it was shown by Gilmore (1921) to be a proximal caudal. Gilmore (1921) noted that the genus Creosaurus was congeneric with Allosaurus, and that the isolated Arundel centrum was more similar to the Late Cretaceous theropod Dryptosaurus aquilunguis (Cope, 1866; Marsh, 1877; Carpenter et al., 1997), and gave it the name ?Dryptosaurus potens. The Arundel centrum lacks any medial constriction and possesses a single, strong ventral keel (Gilmore, 1921).
