Leidy's characterization of the type in his memoir (1859) is as follows, the insertions in square brackets indicating the present writer's references to the generic terms which Leidy had in mind:

"The specimens upon which the latter genus [Deinodon] is based, consist of fragments of about a dozen teeth, of which three-fourths [types of Deinodon] are nearly identical in form with those of Megalosaurus, while the others [types of Aublysodon] are more or less peculiar. The uniformity in shape of the teeth of Megalosaurus would appear to indicate that the three-fourths of the specimens alluded to, belonged to, at most, another species of the same genus [Deinodon], while the remaining specimens would typify a distinct genus [Aublysodon]. However, from the variety in form of the latter specimens, together with the fact that all the specimens present the same general appearance, as regards colour, texture, and constitution, I have been induced to regard them as belonging to a single animal [Deinodon], and feel that it must be left for further discovery to ascertain whether such a view is correct." Comparison with the teeth of  convinces me that Leidy's last expressed view is correct.
