Paleontologists say a mass grave in Utah shows the dinosaurs may not have always been solitary predators as previously thought

Tyrannosaur dinosaurs may not have been solitary predators as long envisioned but more like social carnivores such as wolves, new research announced on Monday has found.

Paleontologists developed the theory while studying a mass tyrannosaur death site found seven years ago in the Grand Staircase-Escalante National Monument in southern Utah, one of two monuments that the Biden administration is considering restoring to their full size after former president Donald Trump shrank them.

Using geochemical analysis of the bones and rock, a team of researchers from the University of Arkansas determined that the dinosaurs died and were buried in the same place and were not the result of fossils washing in from multiple areas.

Kristi Curry Rogers, a biology professor at Macalester College, said this research is a “good start” but more evidence would be needed before determining that the tyrannosaurs were living in a social group.

certain times of the year to take advantage of the herding behavior of other animals and they all simply were in the wrong place at the wrong time together.
