The Tyrannosaurus rex as we believed.

In a groundbreaking discovery of the first T. rex mass death site in the southern U.S., announced Monday by the Utah Bureau of Land Management, scientists found evidence of packlike behavior among the famous ancient predator in the Grand Staircase-Escalante National Monument.

“The new Utah site adds to the growing body of evidence showing that Tyrannosaurs were complex, large predators capable of social behaviors common in many of their living relatives, the birds,” said Dr. Joe Sertich, curator of dinosaurs at the Denver Museum of Nature & Science.

“This discovery should be the tipping point for reconsidering how these top carnivores behaved and hunted across the northern hemisphere during the Cretaceous.”
