Question

Dinosaurs are basically categorised into two separate groups based on which feature?

Answer 1

Dinosaurs are generally categorized into two separate groups based on their posture and locomotion. Sauropods, such as Diplodocus and Brachiosaurus, were large, four-legged dinosaurs that walked on all fours. Theropods, such as Tyrannosaurus rex and Velociraptor, were smaller, bipedal dinosaurs that walked on two legs.

Answer 2

Dinosaurs are basically categorised into two separate groups based on their hip structure. The two groups are known as the Saurischia and the Ornithischia. Saurischian dinosaurs have a lizard-like hip structure, while Ornithischian dinosaurs have a bird-like hip structure.
