Mass fossil site may prove tyrannosaurs lived and hunted in packs like wolves
New Utah site, third mass grave found, bolsters theory ferocious dinosaurs may not have been solitary predators
Tyrannosaur dinosaurs may not have been solitary predators as long envisioned
Ferocious tyrannosaur dinosaurs may not have been solitary predators as long envisioned, but more like social carnivores such as wolves, new research unveiled Monday 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 shrunk them.
