Humans have been marveling at the size of T. rexes ever since first putting a full skeleton together. Now, thanks to research published in April 2021, scientists have a better idea of exactly how many of them once called Earth their (temporary) home. According to the team at the University of California, Berkeley, approximately 2.5 billion of these dinosaurs existed across more than 127,000 generations. They reached this estimate by taking into account the dinosaur's body size, sexual maturity, and energy needs.
