Proceratosaurus

Proceratosaurus was a primitive coelurosaurian theropod that lived in England, Europe in the Early Jurassic Period. It looked somewhat similar to the later Ceratosaurus, for which it is named after, but only due to it also having a hornlike crest.

Despite its name, it is not related to Ceratosaurus, but to the later Tyrannosaurus. Overall, Proceratosaurus was a much more gracile and delicate animal. Recent research has speculated with good supporting evidence that Proceratosaurus is the earliest tyrannosauroid.

Since only part of Proceratosaurus' crest is preserved, it's possible it had a crest similar to Guanlong, ' and '.

Story
Proceratosaurus was successfully recreated by InGen in the lab on Isla Sorna where they were parented and fed in captivity on the island.

Once the cloned Proceratosaurus reached maturity they would be transported to the Jurassic Park on Isla Nublar to live in the Proceratosaur Paddock. However, it is unknown if any were on the island.

Proceratosaurus was among the many dinosaur embryos that Dennis Nedry stole from the Cold Storage Room at the beginning of the 1993 Isla Nublar Incident.

It is unknown if there were any surviving populations after Hurricane Clarissa struck Isla Sorna.
