There were five different types of predatory dinosaur tracks, at least six types of tracks from long-necked herbivorous sauropods, four types of tracks from two-legged herbivorous ornithopods, and six types of tracks from armoured dinosaurs,” lead researcher Steven Salisbury says in a statement. The tracks also provide the only known evidence of stegosaurs in Australia, Salisbury notes.
Where they have the fossils of the feet, they can definitively match the footprint. Similar foot structures have similar but not identical footprints. Four legged herbivores are quite different from two legged carnivores and herbivores.
I don’t know, if I had the appetite of a dinosaur I would not be at all picky about the chow. Omnivores fare better. There had to be some real big eggs lying around, not to mention plenty of road kill what with all those giant feet tromping around.
A degree in paleontology could abolish your skepticism.
