Allosaurus, "Meat Eating " Reptile

 Allosaurus (Al-oh-SAWER-us) Whose name means "strange lizard." I think they were unique not strange. He was a ginormous meat eater with a huge appetite. Who topped the scales at around a mere 2 tons and was about 40 feet long! He had long forearms which had 3 claw fingers.  A small head, it was only 3 foot big with 2 ridges over its eyes. I would definitely run if I seen it coming. His finger claws where 6 inches long. He would leave a mark!

They used their impressive tails for balance. They grabbed their pray with their sharp claws and held on tight so they wouldn't drop their food. Then they proceed to ripe apart their prey with their razor sharp teeth and claws and feast way. Their favorite pray was the ornithiscians and sauropods. It is thought that they  may have hunted in packs or alone. Alleosaurus was the top predator during the Late Jurassic Period.

Allosaurus lived in Canada and U.S.A. in the Late Jurassic Period (about 150 million years ago). Utah has the biggest fossil site in the U.S.A. There where 60 skeletons of juvenile and adult Allosaurus  found at a single site.  As fas as  evolution  goesCoelophysis is 1st because it lived in the Triassic period , Allosaurus is 2nd because it lived in the Jurassic period, and T-Rex is 3rd because it lived in the Cretaceous period. Allosaurus was king in the Jurassic period because he was the fiercest of all hunters.
