  • Like other tyrannosaurids, Tyrannosaurus rex is known to have been carnivorous due primarily to the shape of the teeth. (wikipedia.org)
  • She also proposed that the banana-shaped teeth of Tyrannosaurus rex were designed to withstand the strain of violently struggling prey which would otherwise snap teeth that were sharp, flat and knife-like. (wikipedia.org)
  • A study by Emily J. Rayfield from the University of Bristol further supported that Tyrannosaurus used the puncture and pull feeding strategy, where the Tyrannosaurus would startle its prey with a powerful bite and then drag its teeth back through its prey's flesh and bone. (wikipedia.org)
  • The study found that Tyrannosaurus had a bony skull that was well-adapted to withstand biting and shearing forces, with strong nasal bones that helped it withstand compression and shearing stresses and lacrimal bones that enabled the skull to withstand a variety of stresses. (wikipedia.org)
  • The study also found that the skull redirected much of the strain from biting to the Tyrannosaurus skull's robust nasal bones. (wikipedia.org)
  • He also stated that Tyrannosaurus teeth were different from previous theropods because they were thick from side to side, and while the teeth of many other theropods had roots just as long as the crown, the teeth of Tyrannosaurus had roots that were twice as long as the crowns. (wikipedia.org)
  • He further states that the teeth of Tyrannosaurus didn't look like they were for cutting, but instead looked like they were for pulverizing, crushing and piercing. (wikipedia.org)
  • From these reconstructions, it was estimated that Tyrannosaurus was likely capable of exerting a bite force of between 35 and 57 kN (kilonewtons) (7,800-12,700 pounds force), around ten times as great as the strongest alligator bite. (wikipedia.org)
  • The study also revealed that a juvenile Tyrannosaurus had a bite force of no more than 880 pounds force, or 3.9 kN, and that the bite became more powerful as the animal matured. (wikipedia.org)
  • and published in the journal Scientific Reports indicates that Tyrannosaurus could bite down with around 8,000 pounds force (36 kN) when feeding, exerting a pressure of 431,000 pounds per square inch (3 gigapascals) with their teeth. (wikipedia.org)
  • This adaptation allowed Tyrannosaurus to drive open cracks present in bone during repetitive, mammal-like biting and produce high-pressure fracture arcades, leading to catastrophic explosions of some bones and allowing the theropod to fully exploit the carcasses of other dinosaurs such as hadrosaurs and ceratopsians, giving it access to the mineral salts and marrow within bone that other carnivores in the same environment could not take advantage of.
