In the past, paleontologists have long debated whether the huge dinosaurs lived and hunted alone or in groups.
However, with other findings of pack formations in Alberta, Canada, and Montana, the Utah finding may fossilize the belief of a social T. rex.
In the Canadian discovery, 12 individuals found over 20 years ago by Dr. Philip Currie, many scientists doubted T. rexes had the brainpower to organize into anything complex and thought it was an isolated case. Montana’s site built upon the social theory, but now this third site may bring more certainty to the idea.
