Kentrosaurus was a small stegosaur that once roamed Africa. Its name means 'Pointed Lizard'. Like other stegosaurs Kentrosaurus had spikes on its tail for defence, but its dorsal plates were more spike like than its famous cousin.
Tsintaosaurus was a hadrosaur (or duck-billed dinosaur) found in China. Its name means 'Qindao Lizard'. Like other hadrosaurs it walked on all fours, but was also capable of locomotion on its rear legs alone. They probably lived in herds.
