Leidyosuchus canadensis Lambe, 1907

Many unnumbered isolated teeth, vertebrae, and scutes can be referred to Leidyosuchus canadensis , described by Lambe (1907) on the basis of an almost complete skull and jaws from the Oldman Formation of Alberta. Teeth similar to those of this genus had originally been described by Leidy (1856, p. 73) from the Judith River Formation as Crocodylus humilis , but the term was abandoned by Lambe (1907) on the discovery of much better material. Gilmore (1910) described another skull from the type area of the Lance Formation, Leidyosuchus sternbergi . Leidyosuchus canadensis has priority in the event that species prove to be synonymous. Yet another genus, Deinosuchus , was described by Holland (1909) from the Judith River Formation at Willow Creek, Fergus County. Deinosuchus hatcheri is a very large crocodile known from vertebrae, ribs, and scutes and has not yet been identified in the present collection.
