About Proceratosaurus
What it was like
Proceratosaurus was a small meat eater between 3 and 4.1 meters (10 to 13 feet) long, known from a single skull. It had a thin crest on its snout, which is why it was first thought to be related to Ceratosaurus.
It is now known to be an early relative of Tyrannosaurus, part of a group of crested hunters that includes Guanlong from China.
Its world
It lived in the Middle Jurassic, about 168 to 165 million years ago, in what is now England. Its skull comes from the White Limestone, rock formed in warm, shallow seas around low islands.
How it was found
Huene named Proceratosaurus in 1926. The skull had been found years earlier and first placed in Megalosaurus.
