The Topic about Allosaurus

Allosaurus means different lizard and it was one of the largest meat-eating dinosaurs in the late Jurassic period. Allosaurus was about 12 meters tall (39 feet)and weighed 2-5 tons . It was a lizard hipped dinosaur and was closely related to Tyrannosaurus-Rex.

Body Part
Allosaurus had really short arms with curved and pointy claws that were about 15 centimeter long. It had two powerful legs at the back. It had strong legs because it had to be fast in order to. They needed their powerful legs to catch their prey. They had big jaws to carry and hold on to their prey.Allosaurus had sharp pointy teeth that looked like a sharp knifes. Each tooth was about 10 centimeters (4inches) long. When it chews the meats its head moves from side to side. It tosses it head to help it chew.If it teeth break off it would grow new ones.

Allosaurus lived in the United State Of America. It lived in Wymong USA paleontologist know this because in 1879 they found Allosaurus fossil in North America. They also lived dessert and Forest.

Paleontologist believe that their a lot of theories about how Dinosaurs became extinct but the most populist theory that I know is that a meteorite crashed on to the coast of mexico and that the dust was so big that it covered the whole sun and all the living thinngs had wiped out so that the theory that I know about how dinosaurs became extinct.
