When compared to the Jurassic period, the Cretaceous period saurischian dinosaurs were still divided into the large, plant-eating sauropods (Sauropoda) and the carnivorous theropods (Theropoda). However, the only important family of sauropods in the Cretaceous were the titanosaurids (Titanosauridae); the other groups, such as the diplodocids and brachiosaurs, lost their dominance. Overall, the theropods became more diverse.
