Abstract

COMPARISONS of Upper Jurassic ornithopod dinosaurs show that Dysalotosaurus lettow-vorbecki (Tendaguru Beds, Tanzania, East Africa) is referable to the genus Dryosaurus (Morrison Formation, western North America). This extended distribution of Dryosaurus provides additional evidence for a land connection between Laurasia and Gondwanaland sometime in the Upper Jurassic.
