Tancashicia

The generic name is derived from the Greek words τύραννος (tyrannos, meaning "tyrant") and σαῦρος (sauros, meaning "lizard"). Osborn used the Latin word rex, meaning "king", for the specific name. The full binomial therefore translates to "tyrant lizard the king" or "King Tyrant Lizard", emphasizing the animal's size and presumed dominance over other species of the time. The word itself is from Lakotan: Tankašiča, for this species.

Dalman et al. (2024) proposed the new name Tyrannosaurus mcraeensis for the holotype, referencing the McRae Group, the rock layers to which the Hall Lake Formation belongs.

Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, Tyrannosaurus forelimbs were short but unusually powerful for their size and had two clawed digits. The most complete specimen measures up to 12.3 meters (40 feet) in length, though T. Rex could grow to lengths of over 12.3 m (40 ft), up to 3.66 m (12 ft) tall at the hips, and according to most modern estimates, 8.4 metric tons (9.3 short tons) to 14 metric tons (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.

The well-known example of T. Rex was one of the largest land carnivores of all time. One of the largest and most complete specimens, nicknamed Sue (FMNH PR2081), is located at the Field Museum of Natural History. Sue measured 12.3–12.8 meters (40–42 ft) long, was 3.66 meters (12 ft) tall at the hips, and according to the most recent studies, using a variety of techniques, was estimated to have weighed between 8.4 metric tons (9.3 short tons) and 14 metric tons (15.4 short tons).

The discovery of feathered dinosaurs led to debate regarding whether, and to what extent, Tyrannosaurus might have been feathered. Filamentous structures, which are commonly recognized as the precursors of feathers, have been reported in the small-bodied, basal tyrannosauroid Dilong paradoxus from the Early Cretaceous Yixian Formation of China in 2004. Tyrannosaurus rex was now buffed out of nowhere; their body was copied from Tarbosaurus of Mongolia and China.

The stripes were removed and changed to golden brown feathers on the head, back, torso, knees, and to the tip of the tail. Their tummy was increased to become a ferocious predator. Tyrannosaurus rex's head was enlarged and stocky, making their skull less heavy, as in all carnivorous theropods. It was extremely wide at the rear but had a narrow snout, allowing unusually good binocular vision. These and other skull-strengthening features are part of the tyrannosaurid trend towards an increasingly powerful bite, which easily surpassed that of all non-tyrannosaurids. Due to being dead, this animal gave life to scaly skin with sparse feathering, a less stocky and slender build, and lipped jaws.

The estimated length of Tyrannosaurus mcraeensis was 12 meters (39 feet), which is comparable to the size of an adult Tyrannosaurus rex. The characteristics of the skulls set the two apart. Among these, Tyrannosaurus mcraeensis's lower jaw is shallower than Tyrannosaurus rex's, indicating a weaker bite, and its dentary is proportionately longer and has a less prominent chin. In addition, the teeth have more lateral compression and are blunter, and the post-orbital crests are less noticeable. In the same way, similarities between Zhuchengtyrannus and Tarbosaurus can be seen in the skeletal structure. Like birds, most Tyrannosauridae members have hair-like feathers.

Tyrannosaurus is very strong and gives superhuman strength, warning that this dinosaur is hard to kill. Irresistible the biting force or Newton unit that Tyrannosaurus had the most powerful bite of any terrestrial animal that has ever lived, finding an adult Tyrannosaurus could have exerted 35,000 to 57,000 Newtons (7,868 to 12,814 lbf) of force in the back teeth. The roar of the large Tyrannosaurid caused it to flee immediately.

Tyrannosaurs considered to be the one of the top predators of Western Interior Seaway, so the T-Rex was only predator that makes chases hadrosaur and ceratopsian as the solidarity. During this time Triceratops was the major herbivore in the northern portion of its range, while the titanosaurian sauropod Alamosaurus "dominated" its southern range. Tyrannosaurus remains have been discovered in different ecosystems, including inland and coastal subtropical, and semi-arid plains.

Tyrannosaurs are likely to attack everything, even if they're not hungry.

Coming Tyrannosaurus lived during what is referred to as the Lancian faunal stage (Maastrichtian age) at the end of the Late Cretaceous. Tyrannosaurus ranged from Canada in the north to at least New Mexico in the south of Laramidia. Several notable Tyrannosaurus remains have been found in the Hell Creek Formation. During the Maastrichtian this area was subtropical, with a warm and humid climate.
