Jurassic Predators Quiz – Hunters of the Jurassic

The Jurassic period produced many large meat-eating dinosaurs. In the Late Jurassic Morrison Formation of the western US, Allosaurus, Ceratosaurus and Torvosaurus lived alongside giant sauropods and Stegosaurus.

Allosaurus, named by Othniel Marsh in 1877, was the most common, and a skeleton called Big Al shows many injuries. Ceratosaurus had a horn on its snout, and Torvosaurus, meaning savage lizard, was among the largest, with a species also found in Portugal.

Earlier, Megalosaurus became the first dinosaur ever named, in 1824. Dilophosaurus had twin crests, Cryolophosaurus lived in what is now Antarctica and Yangchuanosaurus hunted in China. Together they show how varied big Jurassic hunters were across the Jurassic world.
