The tyrannosaurus rex is a bipedal carnivorous dinosaur with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, its forelimbs are short but unusually powerful for their size, with two clawed digits. Despite this, they are not used to attack, as the tyrannosaur’s powerful bite is its preferred weapon.

Individuals can grow to lengths of over 40 feet and can weigh up to 20,000 pounds, though most are a bit smaller than this, averaging around 35 feet in length and 17,000 pounds in weight.

The statistics above can also be used to represent other large bipedal carnosaurs, such as the allosaurus.
