allosaurus covered in England in 1676, probably belonged to Megalosaurus. It was the first dinosaur to be scientifically named and described, in the 1820s. And it was one of the 3 creatures that prompted the English paleontologist Richard Owen in 1841 to coin a name for the group; he chose "Dinosauria," meaning "terrible lizards."
With an overall length of 30 ft/9 m, a height of 10 ft/3 m, and an estimated weight in life of 1 US ton/900 kg, Megalosaurus was a massive creature, with the body of a typical carnosaur. A short, muscular neck carried the large head, with its powerful, hinged jaws armed with curved, saw-edged fangs. Its fingers and toes were strong and clawed. With such weapons, Megalosaurus was well equipped to attack and kill the large, long-necked, plant-eating dinosaurs of the day (see pp. 126-133).
Megalosaurus has left its mark clearly in southern England. Trackways of great footprints are found in the limestone rocks, and trace how these bulky bipeds walked upright on 2 legs, their toes pointing slightly inward, long tails maybe swinging from side to side at each step to balance their heavy bodies.
