Add cannibalism to the fearsome attributes of Tyrannosaurus rex, the big-headed
dinosaur that roamed North America 66 million years ago and took no prisoners. A study
released on the scientific website PLoS ONE suggests T-rex made the tooth marks on four
specimens of Tyrannosaurus rex. "If something is dead, it's lunch," said study co-author Gregory
M. Erickson. T. rex, known for "puncture and pull" feeding, left discernible marks in the bones
of its prey. And, researchers said, no other carnivore living at that time could have left such bite
marks in skeletons. They also determined the pattern and nature of the gouges left from bite
marks indicated the attacker was likely feeding on a carcass. Immortalized in the popular culture
and the movie "Jurassic Park," Tyrannosaurus rex is the poster child of prehistoric creatures. The
discovery of T. rex fossils has increased steadily in the past 10 years, Erickson said
