Giganotosaurus

Gigantosaurus was a large carnivorous dinosaur from the Early Cretaceous Period. It was larger than T-Rex and weighed slightly less. The dinosaur has not appeared in any of the Jurassic Park films, but has been featured in the Toy lines and some Video games. It was more lightly build than other carnivores of it's size, and it was specialized in large sauropods. Gigantosaurus preyed on Argentinosaurus a very large sauropod.

Behavior
Gigantosaurus hunted in packs to take down large sauropods like Argentinosaurus. They would have picked one of the slowest, weakest or the sickest ones in the herd. They can be in a pack of seven Gigantosaurus they usually hunt in the forest but sometimes they usually do a ambush attack when they are coming to open plains. During a chase or a charging attack on sauropods they usually try to seperate the slowest member of the herd by trying to scare off the other sauropods to move faster and then have the chance to take down the slow sauropod. Gigantosaurus usually wait for the sauropod to die by the intence heat from the sun making it loose a lot of energy, but sometimes Gigantosaurus would try to kill the sauropod by ripping off chunks of flesh from the back legs. This would make the sauropod very weak and may die by the loss of blood. Once the sauropod has fallen down and died Gigantosaurus will begin feeding on the sauropod, but they usually don't share there feed with other predators even other Giganotosaurus. Gigantosaurus can run the speed at 14 metres per second (31 mph).
