A Megalosaurus was a large meat-eating predator. It's jaws were packed with sharp,serrated teeth which curved backwards into it's mouth. They were ideal for cutting through meat.
We know that it lived about 170 million years ago,at a time when the earth's weather was mild. The world's plants were large and plentiful,as in a rain forest today. There were forest trees such as conifers cycads and ginkgoes ,and ferns and horse-tails grew on the ground. This scene would have been home to Megalosaurus.
Some people belive that the dinosaurs died because a metephore hit earth. Others said that a volcano erupted and all the dinosaurs got wiped out.
