Wolf-like traits may have had the awesome and formidable tyrannosaurs, according to new evidence that scientists have from a new mass grave of such carnivorous dinosaurs in Utah, USA.
Tyrannosaurs may not have hunted on their own, as has been the case so far, but they were probably sociable and engaged in group hunting like wolves.
Paleontologists had developed such a theory a few years ago when they found two other sites in North America, Montana, USA, and Alberta, Canada, where fossils of many Tyrannosaurs were discovered side by side. The third discovery reinforces the suspicions that Tyrannosaurs they were more sociable than lonely.
Researchers at the University of Arkansas, who conducted geochemical analyzes at the new site in southern Utah, according to the British “Guardian” and “Telegraph”, cited by AMPE, concluded that the dinosaur bones were not carried away by the waters from different locations, but the Tyrannosaurs had – indeed – died at the same spot.
Other scientists, however, are not convinced and are waiting to see more information to confirm that the Tyrannosaurs lived and hunted in groups. An alternative theory is that they were lonely in hunting but in difficult times, due to environmental pressures, they gathered in the same area.
