Info
Dilophosaurus (Welles, 1970) > Dilophosaurus wetherilli (Welles, 1954) = Megalosaurus wetherilli (Welles, 1954)
Dilophosaurus > Dilophosaurus sinensis (Hu, 1993)
Dilophosaurus > Dilophosaurus breedorum (Welles, 1995 [manuscript date] vide Welles & Pickering, 1999)
The first of these is 70 pages long and describes in great detail a new species of Dilophosaurus, D. breedorum (named to honor the family of William J. Breed, who assisted Sam Welles in collecting the type specimen). It is based on skeletal material (UCMP 77270, at University of California Museum of Paleontology at Berkeley) including a well preserved partial skull that shows the cranial crests.
The type specimen of Dilophosaurus wetherilli includes a skull lacking the crests, and that when Welles (1970) restored the skull of Dilophosaurus this was the specimen he used for the crests. In 1984 Welles opined that this specimen represented a different species of Dilophosaurus from the type.
His manuscript describing the species remained unpublished during his lifetime, so evidently Stephan Pickering has completed it and gotten it into print. Source George Olshevsky
