[D] Dryosaurus grandis
Describer
Lull, 1911
Info
The material of \\\"Ornithomimus\\\" affinis had been previously described by Marsh (1888) as \\\"Allosaurus medius\\\" and by Lull (1911) as \\\"Dryosaurus grandis\\\". This species \\\"Ornithomimus\\\" affinis was later transferred to a new genus, Archaeornithomimus in 1972 by Russell, based on sharing curved pedal unguals with the Chinese species.
However the Chinese species actually has straight pedal unguals, the curved ones coming from the tyrannosaurid Alectrosaurus. So the two species need not be in the same genus.
