A megalosaur is a large, carnivorous dinosaur from the Middle Jurassic period. Think of it as one of the first giant predators to roam the earth. It was one of the first dinosaurs ever discovered. Megalosaurs walked on two legs and had powerful jaws and sharp teeth. They were fearsome hunters, preying on other dinosaurs. Fossils of megalosaurs have been found in Europe. They play an important role in the history of paleontology. They were among the biggest predators of their time.
