How Big Is A Tyrannosaurus Rex Tooth ?
Tyrannosaurus Rex, also known as the tyrant lizard, was a large bipedal carnivorous dinosaur that lived approximately 68 million years back. Commonly known as T. Rex, they had a massive skull and a long, heavy tail. They were known to be one of the largest known land predators measuring upto 13 meters in length, 4 meters tall and weighing up to 6.8 metric tons each. |

T. Rex had massive skull bones along with some other bones which were fused preventing movement between them. The skull strengthening features gave them an increasingly powerful bite, which easily surpassed that of other non tyrannosaurids. They had a U-shaped upper jaw, while the other dinosaurs generally had V shaped jaws. This increased the amount of tissue and bone a tyrannosaur could rip out with one bite although it increased stress on the front teeth.
The teeth of the T. Rex were differently shaped, a feature that’s called heterodonty. The premaxillary teeth in the front of the upper jaw were closely packed with a ‘D’ cross section. It had reinforced ridges on the rear and tips shaped and sharp like a chisel. The tooth itself had a backward curved profile. This shape reduced the chance of the tooth snapping when the tyrannosaurus bit. The remaining teeth were robust; more widely spaced and also had reinforced ridges. The teeth in the upper jaw were larger than those in the rear of the lower jaw. The largest found tooth so far measure 30 centimeters or 12 inches long including the root -- making it the largest tooth of any carnivorous dinosaur till date.
