It couldn't take down sauropods, but it was the perfect predator for smaller prey items. Its skull would have been used almost like a hatchet to smack down on prey, causing heavy bleeding. However, its weak bite force is misleading. Allosaurus is also known to hunt in packs to kill bigger dinosaurs such as Camarasaurus.Īllosaurus was certainly not the only apex predator in the Jurassic, as it would have to compete against other predators, such as Saurophaganax and not the bigger but the main rivals Ceratosaurus and Torvosaurus. There are currently three species of Allosaurus known: A. Its diet may have included many different dinosaurs, mainly smaller ones such as the Dryosaurus and Camptosaurus, but in packs it may, possibly, have hunted the stegosaurid Stegosaurus, young sauropods, even lonely and/or injured adult Diplodocus. The predator had a large skull with eye ridges, and claws designed for gripping. It grew to about 26 - 33 feet (8 to 10 meters) on average and was capable of reaching up to 12–13 meters (up to 43 feet.) long. Third Evolution Message: The name Allosaurus means "different lizard" in Greek.An artist's illustration of Allosaurus fragilisĪllosaurus (meaning "different lizard"), is arguably one of the most well known Jurassic predators. Second Evolution Message: The movement of the Allosaurus were easy to track, since they left broken teeth alongside its victims. Initial Message: The Allosaurus was the most fearsome and deadly dinosaur before the appearance of the Tyrannosaurus.įirst Evolution Message: The Allosaurus could grow to become an amazing size between 35 and 40 feet long, almost as long as a badminton court. This contrasts pretty well with the T- Rex who was approximately 13-16 feet tall, 42 feet long and weighed approximately 7 tons. The size of the largest Allosaurus is approximately 16 feet tall, 43 feet long and weighed more up to 5 tons.
One interesting fact to note is that the largest Allosaurus specimens may have rivaled the T- Rex in size. It is believed that the Allosaurus was able to attack larger predators with these teeth by using its upper jaw like a hatchet and attacking using the element of surprise. It had rows of razor sharp teeth that had saw-like formations on its edges. This conclusion has been reached in part by the number of razor sharp teeth that can be found in this predator’s mouth. This dinosaur was a large carnivorous bipedal predator that scientists believe preyed on the many herbivores of the time.
