T-Rex

T-Rex

                                                            

The T-rex is from the Cretaceous period 68 to 66 million years ago. It was the last known member of the tyrannosaurids, and among the last non-avian dinosaurs to exist before the Cretaceous- Paleogene extinction event.

The Tyrannosaurus has a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, Tyrannosaurus fore limbs were short but unusually powerful for their size and had two clawed digits.

More than 50 specimens of Tyrannosaurus rex have been identified, some of which are nearly complete skeletons. 

Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, located at the Field Museum of Natural History.

The generic name is derived from the Greek words tupavvoc (tyrannos, meaning" tyrant") and Oavpoc (sauros, meaning "lizard").

The T-rex was one of the largest land predators during its time, which grew at an average length of 43 feet or 13 meters. Although some dinosaurs exceeded or even competed with its size, it was still considered the biggest carnivore in that period. At the hips, it measured approximately 13 feet or 4 meters high. The average T-rex weighed more or less 7.5 short tons or 6.8 metric tons. It was an apex predator, which preyed on ceratopsians and hadrosaurs. However, some paleontologists believe that the T-rex was more of a scavenger rather than an apex predator.
