Tyrannosaurs possibily lived and hunted in packs

In July 2014, researchers looking for fossil turtles in southern Utah’s public lands found hints of a “monstrous murderer”: the ankle bone of a tyrannosaur named Teratophoneus. Within hours, they had brushed through the sand between pinyon junipers and found the jumbled remains of multiple Teratophoneus—all of which seemed to have died in the same place, at the same time.

Scientists unveiled the site to the world in a study published last Tuesday in the scientific journal PeerJ, suggesting tyrannosaurs congregated in social groups. “Dinosaur behavior, dinosaur ecology, is probably always going to turn out a little more complex than we think at any given time,” says lead study author Alan Titus, a paleontologist with the U.S. Bureau of Land Management who works in Grand Staircase-Escalante National Monument, where the site is located. 

Titus even thinks that the site could be evidence that tyrannosaurs worked together as cooperative pack hunters. “Now you’ve got these giant terrestrial predators behaving in a group, much more akin to a pack of wolves and a pride of lions, [which] is staggering,” he says.

The new fossils are not the first example of tyrannosaurs discovered in the same place, but a meticulous reconstruction of the area’s geologic history provides strong evidence that they died in a group. The more elusive question is what they were doing together.

Thomas Carr, a paleontologist at Carthage College in Kenosha, Wisconsin, who wasn’t involved with the new study, says that finding more signs of social dinosaurs shouldn’t necessarily come as a surprise. Extinct dinosaurs belong to a bigger group called the archosaurs, which includes social animals such as modern birds, alligators, and crocodiles.
