The finding, based on research at a unique fossil bone site inside Utah s Grand Staircase-Escalante National Monument containing the remains of several dinosaurs of the same species, was made by a team of scientists including Celina Suarez, University of Arkansas associate professor of geosciences.

The Tyrannosaurus rex may not have been as solitary as we previously have 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 pack-like behavior among the famous ancient predator in the Grand Staircase-Escalante National Monument.
To celebrate the discovery, key scientists held a press conference with panelists including BLM Paria River District Paleontologist Dr. Alan Titus, University of Arkansas Dr. Celina Suarez and Denver Museum of Nature and Science Curator of Dinosaurs Dr. Joe Sertich. 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,” Sertich said. “This discovery should be the tipping point for reconsidering how these top carnivores behaved and hunted across the northern hemisphere during the C
