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.

A new study suggests that up to 2.5 billion Tyrannosaurus Rex dinosaurs lived on Earth over a period of a few million years.
However, the research shows that not many of these powerful creatures lived in the same place at the same time.
Tyrannosaurus Rex, commonly known as T. rex, existed on Earth for millions of years. Scientists involved in the study estimate about 2.5 billion of them lived over a period of 2.4 million years. The dinosaurs mostly lived in the area of the world now known as North America.

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.
