Tyrannosaurus Rex AteTyrannosaurus Rex At Jurassic Period

Tyrannosaurus Rex was the undisputed king of the dinosaurs. They eat each other. The Yale researcher Nick Longrich found vast gouges in the bone of a Tyrannosaurus rex.

He said, “They’re the kind of marks that any big carnivore could have made,” said Longrich, “but Tyrannosaurus rex was the only big carnivore in western North America 65 million years ago.”

Longrich unremitting to investigate for other signs of Tyrannosaurus rex cannibalization and excavated a total of three foot bones and one arm bone that showed signs of being chobbled on by another Tyrannosaurus rex, which, allowing for the amount of fossils we have represents a important proportion.
“It’s surprising how frequent it appears to have been,” Longrich said. “We’re not exactly sure what that means.”

The symbols on the bones are convincingly the result of feeding, but whether the cannibalization was a result of the behemoth’s skirmishing each other to the death, or simply that of scavenging for food, is unidentified.

“Modern big carnivores do this all the time,” he said. “It’s a convenient way to take out the competition and get a bit of food at the same time.”

These conclusions are an unlooked-for clue into the lives of one of the more hidden dinosaurs. “They were some of the largest terrestrial carnivores of all time, and the way they approached eating was basically unusual from modern species,” Longrich said. “There’s a big mystery around what and how they ate, and this research helps to uncover one piece of the puzzle.”
