Theropoda

In recent years, there has been an increasing number of dinosaur bones discovered in more and more places around the world. The evidence discovered in the bones tells us that the various dinosaurs we have discovered are not all closely related to one another. Generally, they have evolved along two parallel lines. The differences seen in their arrangement of the teeth in the jaws, as well as the number of hip bones tell us that there have been two main kinds of dinosaur. Each of these kinds includes dinosaurs that used to walk on their hind legs and dinosaurs walked on all fours. The kind that walked on hind legs (and were carnivores) is referred to as the Theropoda, while the latter is called the Sauropoda (plant eaters).
