Unlike mammal teeth, individual dinosaur teeth are generally not considered by paleontologists to be diagnostic to the genus or species level for ...

In the mid-to-late 19th century many dinosaur taxa were named for isolated teeth; such genera include Trachodon, Palaeoscincus, and Troodon.Even before the badlands of North America started revealing the bones of Tyrannosaurus, teeth turning up in many localities in the Western United States revealed the presence of large predatory dinosaurs.
