A recent study from the University of California, Berkeley has revealed that over the course of a few million years, an approximate 2.5 billion Tyrannosaurus rexdinosaurs roamed the Earth.
The research factored in the 127,000 generations, the 1.2 million to 3.6 million years of their existence, along with its sexual maturity of 14 to 17 years, and max life span of 28 years. Due to the size of the T-Rex, it was also determined that the carnivore required a substantial amount of energy, which ultimately means a lower population density it was worked out that there was an estimated two in a place the size of Washington, D.C., or 3,800 in California.

One Tyrannosaurus rex seems scary enough. Now picture 2.5 billion of them. That’s how many of the fierce dinosaur king probably roamed Earth over the course of a couple million years, a new study finds.
Using calculations based on body size, sexual maturity and the creatures’ energy needs, a team at the University of California, Berkeley figured out just how many T. rex lived over 127,000 generations, according to a study in Thursday’s journal Science. It’s a first-of-its-kind number, but just an estimate with a margin of error that is the size of a T. rex.

If one Tyrannosaurus rex the school bus-sized meat-eating dinosaur that stalked the Cretaceous Period landscape seems impressive, how about 2.5 billion of them?
Researchers on Thursday unveiled the first calculation of the total T. rex population during the estimated 2.4 million years that this fearsome species inhabited western North America during the twilight of the age of dinosaurs.
They considered factors including the size of its geographic range, its body mass, growth pattern, age at sexual maturity, life expectancy, duration of a single generation and the total time that T. rex existed before extinction 66 million years ago. They also heeded a doctrine called Damuth s law linking population to
