Tyrannosaurus Rex:  A full-grown Tyrannosaurus rex stood fifteen feet tall and was nearly twice as heavy as a bull elephant.  It possessed one of the largest brains ever evolved in the animal kingdom, even larger than those of most mammals that have ever lived.  That magnificent brain was the engine powering one of the most ferocious carnivores of all time.

Keen eyes glared from its massive head, and when those cavernous jaws opened wide they revealed dangerous rows of eight-inch teeth. Tyrannosaurus rex was truly the King of the Dinosaurs!
