Proceratosaurus was a primitive coelurosaurian theropod that lived in England, Europe in the Middle Jurassic Period. It looked somewhat similar to the later Ceratosaurus, for which it is named after, but only due to it also having a horn-like 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, Kileskus and Sinotyrannus.

Proceratosaurus DNA was successfully collected by InGen and viable embryos have been created, through the animal never made it past that stage. However, a paddock was created before the 1993 incident.

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.[1] As confirmed by the Dinosaur Protection Group, the only viable embryos on Nublar were all destroyed due to water damage to the cool room during the incident, and so all of InGen's DNA samples were lost during the evacuation of Site B. Its status was set to 'terminated' until new DNA samples were recovered.

Jurassic World: Alive

Proceratosaurus is one of the creatures featured in Jurassic World: Alive. This is the first time it has ever physically appeared in any Jurassic Park game. An interesting feature to the Proceratosaurus in the game is that it has fur-like feathers, which it likely had in reality.

Jurassic World: Fallen Kingdom

A Proceratosaurus figure will be released as part of the toy-line for Jurassic World: Fallen Kingdom, as part of the "Attack Pack" line. This will be the first time it has ever physically appeared in any Jurassic Park toy set. Apparently, the toy bares resemblance to the Jurassic Park Institute Artwork.
