Jurassic Park Wiki

Megalosaurus was the first dinosaur ever to be discovered. Sir Richard Owen described it as a large monitor lizard due to its teeth that look so similar. The face of Megalosaurus remains a mystery. Dr. Thomas R. Holtz says it might be an ancestor of the spinosaurids; many scientists agreed with him. Others say it's a carnosaur. The most complete skeleton which has 22 percent of Megalosaurus had more details of a spinosaurid than a carnosaur.
