The actual number fluctuates through time, as new species are discovered, and others are shown to be invalid through research broadly known as taxonomy. The iconic Tyrannosaurus rex is a ferocious predator with razor-sharp teeth that lived 68 million years ago during the Late Cretaceous period.

Billions of T. rex likely roamed the Earth, paleontologists report In recent years, research suggests that juveniles were almost like a different species.

I dont think many of us who are sort of the, lets say, skeletally focused paleontologists have thought this would be possible, but I think its really eye-opening in that sense., Dr. Makovicky said when he read the paper, he started searching for populations of large predatory animals today to compare with the estimate of 20,000 T. rexes. Web"Claire, be careful. The same computer simulations indicated, with 97.5 percent probability, that there were at least 1,300 adults but not more than 328,000.
