|Scientific name||Mapusaurus roseae|
|Creature type||Theropod Dinosaur|
Mapusaurus is a large theropod dinosaur from the Early Cretaceous of South America.
When Connor accidentally drove the car into the anomaly at the co-operative supermarket in Olney, they encountered a pack of Mapusaurus, which then started chasing the team. They hid up a tree in a conifer forest to be safe from them. They could also see a herd of Argentinosaurus with one being attacked by a Mapusaurus. A Mapusaurus also came through the anomaly chasing a Macrogryphosaurus buut they are returned through the anomaly. (Episode 1.4)
The large theropod dinosaur Mapusaurus was discovered all at once, and in a big heap--an excavation in South America in 1995 yielded hundreds of jumbled bones, which required years to sort out and analyze. It wasn't until 2006 that researchers announced the "diagnosis" of Mapusaurus, which was closely related to the even bigger Giganotosaurus and must have been one of the most feared hunters of its day.
Interestingly, the fact that so many Mapusaurus bones were found jumbled together can be taken as evidence of herd, or pack, behavior--raising the possibility that this dinosaur hunted cooperatively in order to take down the huge titanosaurs populating middle Cretaceous South America. On the other hand, a flash flood could also have resulted in the accumulation of unrelated Mapusaurus bones, so the pack-hunting hypothesis should be taken with a big grain of prehistoric salt.
This dinosaur was a giant South American meat-eating dinosaur with blade-like teeth for slicing off chunks of sauropod flesh. At over ten metres long Mapusaurus was similar in size to the closely related Giganotosaurus. Fossils from at least seven individuals of various ages were discovered in a bone bed in Argentina. This may suggest they worked in groups to take down the large sauropods of the time, such as the colossal Argentinosaurus, something a single Mapusaurus may not have been able to accomplish alone. Alternatively this group find may represent a simple predator-trap.
