Tyrannosaurus-rex was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, Tyrannosaurus-rex forelimbs were short but unusually powerful for their size and had two clawed digits.
The most complete specimen measures up to 40 feet in length though T. rex could grow to lengths of over 40 feet, up to 12 feet tall at the hips, and according to most modern estimates 9.3 short tons to 15.4 short tons in weight.
Although other theropods rivaled or exceeded Tyrannosaurus-rex in size, it is still among the largest known land predators and is estimated to have exerted the strongest bite force among all terrestrial animals. By far the largest carnivore in its environment, Tyrannosaurus-rex was most likely an apex predator, preying upon hadrosaurs, armored herbivores like ceratopsians and ankylosaurs, and possibly sauropods.
Some experts have suggested the dinosaur was primarily a scavenger. The question of whether Tyrannosaurus was an apex predator or a pure scavenger was among the longest debates in paleontology. Most paleontologists today accept that Tyrannosaurus-rex was both an active predator and a scavenger.
More than fifty major specimens of Tyrannosaurus-rex have been identified, some of which are nearly complete skeletons. Soft tissue and proteins have been reported in at least one of these specimens.
The abundance of fossil material has allowed significant research into many aspects of its biology, including its life history and biomechanics. The feeding habits, physiology and potential speed of Tyrannosaurus-rex are a few subjects of debate.
Its taxonomy is also controversial, as some scientists consider Tarbosaurus bataar from Asia to be a second Tyrannosaurus species while others maintain Tarbosaurus is a separate genus. Several other genera of North American tyrannosaurids have also been synonymized with Tyrannosaurus.
