Tyrannosaurus rex

Tyrannosaurus[nb 1] is a genus of large theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), often called T. rex or colloquially T-Rex, is one of the best represented theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the Upper Cretaceous period, 68 to 66 million years ago. It was the last known member of the tyrannosaurids and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Source: Objaverse 1.0 / Sketchfab

FIGURE 3 in Maximum Bite Force and Prey Size of Tyrannosaurus rex and Their Relationships to the Inference of Feeding Behavior

FIGURE 3 Cranial morphology and jaw adductor musculature. Differences in the posterior width of the skull, relative to the tooth rows, may be constrained, together with tooth shape, by biting strategies such as crushing or penetration. The rather broadly-set tooth rows of Allosaurus fragilis (illustration modified after Madsen, 1976) appear to provide most theropods with a sufficiently concentrated bite force to facilitate lethal, penetrating bites. The expanded posterior part of the skull of Tyrannosaurus rex allowed for jaw adductor muscles with more cross-sectional area (illustration modified after Osborn, 1912). This suggests an atypically high bite force in this taxon, compared to most other theropods. The combination of a high bite force with comparatively broad, conical teeth implies adaptation for crushing the relatively greater mass of flesh and/or bones of large prey. This suggests that T. rex may have fed in significantly different ways from the majority of large theropods.

FIGURE 1 in Maximum Bite Force and Prey Size of Tyrannosaurus rex and Their Relationships to the Inference of Feeding Behavior

FIGURE 1 Effect of prey size on penetrating bites. Non-vital tissues of prey animals, such as integument and muscle, serve as barriers to predators seeking to inflict lethal damage on their prey. Assuming some minimum depth of penetration is required for a lethal bite, the depth of tissue through which a predator's teeth must penetrate increases linearly with increasing prey size. However, frictional resistance between flesh and teeth increases more rapidly than this. For a simple cone, frictional resistance increases with the square of the linear increase in depth of penetration. This results, for example, in four times the amount of frictional resistance to penetration that is twice as deep. A subconical tooth of Tyrannosaurus rex was modeled by computer and its engaged surface area was calculated for bites to 2 and 4 cm depth. In the latter case, the surface area of the tooth engaged is approximately three times that for a 2cmbite, due to the moderate lateral compression of T. rex teeth.

FIGURE 2 in Maximum Bite Force and Prey Size of Tyrannosaurus rex and Their Relationships to the Inference of Feeding Behavior

FIGURE 2 Skull morphology and crushing bites. Typical theropods have dentary teeth that are aligned just medial to the maxillary teeth, (a) This results in forces that are almost directly opposed when the teeth, exemplified here by those of Allosaurus fragilis, engage a food item, (b) In contrast, the dentary and maxillary teeth of Tyrannosaurus rex do not generate directly opposed forces in biting. Rather, the medially aligned dentaries tend to concentrate force near midline. In bilateral biting, the resulting stress on the prey is well-suited to crushing either bone or soft tissues.
