Megalosaurus was the first dinosaur to be discovered ever. 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 while 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. Megalosaurus might have been 34 ft long, weighed 4 tons and is assigned to its own family: Template:W. Template:Wikipediainfo
