Dinosaur Sculptures at Crystal World – Tyrannosaurus

Tyrannosaurus is a genus of large theropod dinosaur. The speciesTyrannosaurus rex (rex meaning “king” in Latin), often colloquially called ‘T-Rex,’ is one of the best represented theropods. It lived throughout what is now western North America, on what was then an island continent known as LaramidiaFossils are found in a variety of rock formations dating to the Maastrichtian age of the Upper 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.

Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, the forelimbs of Tyrannosaurus were short but unusually powerful for their size, and they had two clawed digits. Tyrannosaurus are estimated to measures up to 12.4 m in length, up to 3.96 m tall at the hips, and 8.87 metric tons in body mass.

Tyrannosaurus lived during what is referred to as the Lancian faunal stage (Maastrichtian age) at the end of the Late Cretaceous. Tyrannosaurus ranged from Canada in the north to at least New Mexico in the south of Laramidia. During this time Triceratops was the major herbivore in the northern portion of its range, while the titanosaurian sauropod Alamosaurus “dominated” its southern range. Tyrannosaurus remains have been discovered in different ecosystems, including inland and coastal subtropical, and semi-arid plains. According to studies, the total population of adult Tyrannosaurus at any given time was anywhere around 20,000 individuals, with computer estimations also suggesting a total population no lower than 1,300 and no higher than 328,000.
