found in North America, Europe, and Africa. This makes it a very wide ranging dinosaur. It's also the most commonly found large theropod from the Jurassic.
Allosaurus was your basic theropod. It had a large head and a number of sharp teeth. It's arms were long and each finger was tipped with a 6-7 inch claw. Allosaurus had long, powerful back legs. Scientists estimate allosaurus could have hit over 20 miles per hour. Like it's cousins, Allosaurus also had crests on it's head, one above each eye.
SizeEditAllosaurus varied some in overall size. The smallest specimens are roughly 26 feet(8 meters) long, stand just under 9 feet(3 meters) tall, and weigh an estimated 1-2 tons. The largest however, stretch nearly 36 feet(11 meters) long, stand over 13 feet(4 meters) tall, and weigh over 3-3.5 tons. Allosaurus tends to average about 30-33 feet(9-10 meters) long and about 2-3 tons.
Allosaurus had a somewhat weak "standard" bite force. It's estimated to have bitten down with roughly 1,000-1,500 pounds per square inch. However, Allosaurus was able to open it's jaws very widely. It would then swing it's upper jaw down in a slashing action. This would have produced over 4,000 pounds of force per square inch.
