Megalosaurus, which means “great lizard”, is an extinct genus that includes large carnivorous dinosaurs. It was found in Southern England’s Middle Jurassic (Bathonian) stage (166 million years ago). Megalosaurus fossils have been found in other parts of the world, but the only known remains are from Oxfordshire. They date back to the middle Jurassic.

Megalosaurus, a genus of nonavian dinosaurs, was first to be named in 1824. Megalosaurus bucklandii was named in 1827 as the type species. Richard Owen’s Dinosauria was based on Megalosaurus in 1842. Owen directed the creation of a model for one of the Crystal Palace Dinosaurs. This greatly increased public interest in prehistoric reptiles. The genus would later include over 50 other species. This was originally due to the fact that dinosaurs were not well-known, even though many had been discovered in the 20th century. It is now understood that these additional species are not related to Megalosaurus species M. bucklandii. Its build is not known as it remains incompletely skeleton.

Megalosaurus was misunderstood by the first naturalists to investigate it. It measured 20m (66ft) in length. Owen in 1842 concluded that the creature was only 9 meters (30 ft) long, standing on its upright legs. It was still a quadruped though, Owen believed. Modern scientists were able to get a better picture of Megalosaurus by comparing it with its Megalosauridae relatives. Megalosaurus weighed in at 700 kg (1,500 lb) and measured 6 meters (20 feet). It was bipedal and walked on strong hindlimbs. The horizontal tail balanced its horizontal torso. Although its forelimbs were very strong, they were quite short. Megalosaurus was a large, curved-toothed dinosaur with a head that measured approximately 3.5 meters in length. It was a strong and muscular animal.
