Sauroposeidon towers over Deinonychus. In fact, its mammoth size is its primary defense. But this giant begins life very small. For Deinonychus, Sauroposeiden would be a great meal, at least the juveniles, because there wouldve been lots of them and

And Sauroposeidon like most plant eaters are smelly. Unlike a meat eater, they produce huge amounts of waste, feces that form a trail marking everywhere theyve been. For Deinonychus, that odor is a dead giveaway. And this carnivores eyes can clearly

They are actually increasing their chance of getting a meal. Its a strategy still used today. Working together, lions will take on prey as big as a four-ton elephant, and they only have teeth and claws. Deinonychus employs an array of weaponry more p
