Abstract

The hind foot and portions of the limb of a small ornithopod dinosaur were described by Gilmore as Laosaurus minimus. The locality, in the foothills of southern Alberta, was supposed to be Lower Cretaceous, but more recent studies indicate that it is Upper Cretaceous. An examination of Gilmore's type shows that it differs from the hind feet of Laosaurus, as well as those of all known American and Asiatic ornithopods. Closest comparison is with Hypsilophodon foxii, from the Lower Cretaceous of England. Temporary designation of Gilmore's species as "Laosaurus" minimus is proposed.
