The iconic T. rex is a member of this group of dinosaurs, with the tiny Microraptor at the other end of the scale.

The theropods were a diverse group of dinosaurs. They walked on two legs, were mostly meat-eaters, and all had three-toed limbs.


Theropods all had hollow bones, something they have in common with their descendants, modern birds.

They include the iconic T. rex, as well as Velociraptor, Spinosaurus and Compsognathus, of Jurassic Park fame.
