Mapusaurus was a carnivorus dinosaur that lived 95 million years ago in Argentina. It may have preyed on the giant titanosaur Argentinosaurus. However this sauropod was too large to be killed by just one of these predators, it is believed they may have hunted in packs to bring the the Argentinosaurus to its knees. Just one Argentinosaurus would feed a pack of Mapusaurus for days.
