Allosaurus is a genus of large carnivorous theropod dinosaur that lived 155 to 145 million years ago during the late Jurassic period. The name "Allosaurus" means "different lizard" alluding to its unique concave vertebrae. It is derived from the Greek ἄλλος and σαῦρος. Allosaurus could reach lengths of 39 feet, and weigh up to 3,900 lbs.
Diet- Allosaurus hunted large herbivores such as ornithopods, sauropods, and stegosaurs. Fossil "predation" evidence suggests scrapes and bite marks on fossil bones of sauropods and stegosaurs which match Allosaurus shaped teeth. Allosaurus would have likely preyed the live animals, and scavenged for carcasses as well.
