This is the big one!! The species Tyrannosaurus rex (rex meaning "king" in Latin), is one of the most well-represented of the large theropods. Tyrannosaurus lived throughout what is now western North America and is found in rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 68 to 66 million years ago. The T-Rex was a bipedal carnivore with a massive skull balanced by a long, heavy tail and it is still among the largest known land predators and is estimated to have exerted the largest bite force among all terrestrial animals. By far the largest carnivore in its environment, T-Rex was most likely an apex predator, preying upon hadrosaurs, armoured herbivores like ceratopsians and ankylosaurs, and possibly sauropods. This fossil has wisps of red throughout the mineralization which is very rare. A must for all “gaming predators”….
