Megalosaurus (meaning "Great Lizard", from Greek μέγας, megas, meaning 'big', 'tall' or 'great' and σαῦρος, sauros, meaning 'lizard') is a genus of large meat-eating theropod dinosaurs of the Middle Jurassic period (Bathonian stage, 166 million years ago) of Southern England. Although fossils from other areas have been assigned to the genus, the only certain remains of Megalosaurus come from the late Middle Jurassic of the Oxfordshire. Megalosaurus was about seven metres long, weighing about 1.1 tonnes. It was bipedal, walking on stout hindlimbs, its horizontal torso balanced by a horizontal tail. Its forelimbs were short, though very robust. Megalosaurus had a rather large head, equipped with long curved teeth. It was generally a robust and heavily muscled animal. Fortunately, before being extinct due to climate change and rapid competition between it and other theropods, the species was saved by the Zhecrons and were then given a new home on their homeworld. Ever since, the Megalosaurus population has doubled into approximately 750,000 members. Some usually hunt within the vast forests that parallel that of Cretaceous England, some dwelled within the jungles, while others spend their time in the plains.
