The King of Dinosaurs – Tyrannosaurus Rex

44

Tyrannosaurus (Greek for ‘tyrant lizard’) Rex (Latin for ‘king’) was perhaps one of the largest to have once walked the face of the planet during the late Cretaceous period (approximately 85 to 65 million years ago).

Formerly regarded as the king of dinosaurs, Tyrannosaurus Rex was measured to have grown around 40 feet in length, its massive skull covering 5 feet; between 15 to 20 feet in height; and at least 6 tons in weight. Clearly not designed for gripping its prey, the entity’s pitifully shrunken arms would only serve as a standing contrast to its massive bulk. Its stride ranging between 12 to 15 feet, Tyrannosaurus Rex was estimated to have been not so much capable of running as walking at a quick pace at a speed of about 15 mph. The beast’s long tail played an important role as well in its locomotion as a counterbalance to the weight of its skull.

As opposed to the knifelike trend among the dentition of a majority of flesh-eating carnivores, Tyrannosaurus Rex possessed a fearsome set of banana-shaped teeth measuring approximately 6 inches long, which it sheds cyclically as a modern shark would. With its forelimbs rendered incapable of anything beyond being merely a vestigial display, Tyrannosaurus Rex relied mostly on its teeth to seize food before ripping the flesh off with its muscular neck.

From the enormous size of its maw, it was deduced that Tyrannosaurus Rex was able to consume approximately 500 pounds and flesh and bones with a single bite. Its diet mostly consisted of the plant-eating population of the time, the ceratopsians and hadrosaurs, the remains of which supported the theory that the beast pulverized their bones in one feeding session.

There is an ongoing debate as to whether Tyrannosaurus Rex was once a scavenger or a predator. Reasons backing up the notion that the beast once scavenged for a living on the carcasses left behind by other predators of the time include its lack of acute vision, truncated forelimbs and huge lumbering legs, all of which do not apply to the popular perception of a predator. It was also thought to have been cannibalistic in nature, as suggested by the bite marks of a Tyrannosaurus Rex on the bones of its peer found in Montana in 2010, though it might have been due to a scuffle between each other as well, an occurrence commonly observed in most species.

So far, a handful of dinosaurs such as Giganotosaurus and Carcharodontosaurus had been discovered to be slightly larger than Tyrannosaurus Rex, effectively usurping it from its position as the king of all dinosaurs. In 2006, the remains of Mapusaurus, dating back to 100 million years ago, was discovered in Argentina and was deduced to have belonged to a creature possibly larger than Giganotosaurus itself.
