Allosaurus

The skull of the Jurassic killer Allosaurus bites down on the skeleton of a hapless Camptosaurus.

Growing up to 13 metres in length, Allosaurus was the most common carnivorous dinosaurs in Jurassic North America. Smaller meat-eating dinosaurs such as Ornitholestes may have hunted in packs and scavenged the kills of these larger predators.

More than 40 individuals, some up to 13 metres long, are represented in a single quarry in Utah.
