Researchers on Thursday unveiled the first calculation of the total T. rex population, putting the number at 2.5 billion over 125,000 generations.
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.
Using geochemical analysis of the bones and rock, a team of researchers with 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.
Tyrannosaurus rex the tyrant lizard king may not have been a solitary predator, but instead hunted its prey in packs, just like wolves, a study has suggested.
Palaeontologists have been studying a T. rex mass death site found back in 2014 in the Grand Staircase-Escalante National Monument in southern Utah.
Analysis of the fossil bones and the surrounding rock has revealed that the dinosaurs died and were buried together, rather than being washed in from other places.

The dinosaur remains were found in the Grand Staircase-Escalante National Monument in Utah.
Scientists had previously thought that the tyrannosaurs brains were too small for this kind of complex behavior.
Tyrannosaurs were probably social animals who hunted in packs, according to research from the University of Arkansas published Monday.
The research challenges a common theory that the huge lizards were solitary hunters who chased down prey alone, perhaps because they were too stupid to cooperate.
The tyrannosaur category includes the famous Tyrannosaurus rex as well as similar-looking carnivores likes the Albertosaurus and Gorgosaurus. A lot of researchers feel like these animals simply didn t have the brain power to engage in such complex behavior, Alan Titus, a paleontologist for the Bureau of Land Management who led the research, told reporters in an online briefing, The Washington Post reported.
