About Proceratosaurus:

When its skull was first discovered--in England way back in 1910--Proceratosaurus was thought to have been related to the similarly crested Ceratosaurus, which lived much later. Today, though, paleontologists identify this middle-Jurassic predator as more similar to small, early theropods like Coelurus and Compsognathus. Despite its relatively small size, the 500-pound Proceratosaurus was one of the biggest hunters of its day, since the tyrannosaurs and other large theropods of the middle Jurassic had yet to attain their maximum sizes.
