Over approximately 2.5 million years, North America was likely home to 2.5 billion Tyrannosaurus rexes. Less than 100 have been dug up and studied by paleontologists, according to a UC Berkeley study( Image by Julius Csotonyi, courtesy of Science magazine)

Already in the first few months of 2021, new findings about the Tyrannosaurus rex have shifted paleontologists picture of how the dinosaur hunted, moved, and grew into a fearsome predator.
Researchers also determined that the T. rex developed stiff, bone-crushing jaws once it became an adult, after experiencing a huge growth spurt during its teenage years.
The previously held idea that this type of dinosaur preferred a solo lifestyle has also been called into question: A recent fossil finding suggests a pack of Tyrannosaurs died together while hunting.
Reconstructing the behavior of a predator that hasn t walked on the Earth in over 66 million years isn t easy. But the T. rex is such a compelling creature that paleontologists continue to pore over its fossils.
