What is characteristic of Saurischian dinosaur?

Saurischian dinosaurs are characterized by their hip structure, which features a pubis bone that points downward and forward, resembling that of modern reptiles. This group includes two main subcategories: theropods, which are primarily bipedal and include birds as their descendants, and sauropodomorphs, which are primarily large, long-necked herbivores. Saurischians are known for their diverse body sizes and adaptations, ranging from small, agile predators to massive, slow-moving giants.
