It looks like we've probably got the biggest meat-eater in the world.But there was more.When Rodolfo and his team began to study the bones in detail, they noticed something strange.As they analyzed the bones, Rodolfo realized that they had found four leg bones...for a two-legged creature.There was more than one carnivore in this dinosaur graveyard.So far, our record is indicating that at least six individuals have been preserved.What's more, they were all different ages.With six specimens of the new meat-eating dinosaur found at the Argentinian site,Phil Currie had what he needed - the second pack of mega-carnivores.I just couldn't believe it because...Suddenly here we were in situation where we had two large meat-eating dinosaurs in two parts of the world which were showing packing behavior.
