Megalosauridae is a family of large theropod dinosaurs. They lived during the Jurassic and Cretaceous periods. Imagine them as some of the earliest known big meat-eaters. These dinosaurs were characterized by their strong builds and powerful jaws. They were among the first dinosaur fossils ever discovered. Megalosaurids represent an important step in understanding theropod evolution. They are typically medium to large sized, with lengths from 6-9 meters. Their fossils have been found in Europe, North America, and Asia.
