Saurischians

Meet the Saurischians, the super cool dinosaur group with a special hip structure that sets them apart from all the rest!

The name Saurischian means “lizard-hipped,” and this group includes some of the most famous dinosaurs ever, like the mighty T-Rex and the enormous Brachiosaurus.

These awesome dinos are divided into two major groups: the theropods, who were fierce meat-eaters like T-Rex and Velociraptor, and the sauropodomorphs, who were gentle giants with long necks like Brachiosaurus and Diplodocus.

Whether they were chasing prey or munching on treetops, Saurischians ruled the prehistoric world with their unique hip bones and incredible variety.

Imagine all these different dinosaurs, each with their amazing abilities, living in the same ancient world – that’s what makes Saurischians so fascinating!
