Dinosaur Tracks Suggest Tyrannosaurs Hunted in Packs
[An Nahar] Some 70 million years ago, three tyrannosaurs stalked together across a mud flat in Canada, possibly searching for prey.The new insight comes from several parallel tyrannosaur tracks unearthed in Canada. The dinosaur tracks provide stronger evidence for a controversial theory: That the fearsome mega-predators hunted in packs. The ferocious beasts may have "stuck together as a pack to increase their chances of bringing down prey and individually surviving," said study co-author Richard McCrea, a curator at the Peace Region Palaeontology Center in Canada.
