hello hello!! I'm soon planning to post less math-heavy videos as a change of pace. More qualitative things like competence, tactics, and skill. No promises though 😜 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, the forelimbs of Tyrannosaurus were short but unusually powerful for their size, and they had two clawed digits. The most complete specimen measures 12.3–12.4 m (40–41 ft) in length, but according to most modern estimates, Tyrannosaurus could have exceeded sizes of 13 m (43 ft) in length, 3.7–4 m (12–13 ft) in hip height, and 8.8 t (8.7 long tons; 9.7 short tons) in mass. Although some other theropods might have rivaled or exceeded Tyrannosaurus in size, it is still among the largest known land predators, with its estimated bite force being the largest among all terrestrial animals. By far the largest carnivore in its environment, Tyrannosaurus rex was most likely an apex predator, preying upon hadrosaurs, juvenile 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 was both a predator and a scavenger. Some specimens of Tyrannosaurus rex 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 the animal's 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. The Asian Tarbosaurus bataar is very closely related to Tyrannosaurus and has sometimes been seen as a species of this genus. Several North American tyrannosaurids have been synonymized with Tyrannosaurus, while some Tyrannosaurus specimens have been proposed as distinct species. The validity of these species, such as the more recently discovered T. mcraeensis, is contentious. Tyrannosaurus has been one of the best-known dinosaurs since the early 20th century. Science writer Riley Black has called it the "ultimate dinosaur". Its fossils have been a popular attraction in museums and it has appeared in media like Jurassic Park. Tyrannosaurus (/tɪˌrænəˈsɔːrəs, taɪ-/)[a] is a genus of large theropod dinosaur. The type species Tyrannosaurus rex (rex meaning 'king' in Latin), often shortened to T. rex or colloquially t-rex, is one of the best represented theropods. It 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 geological formations which have been dated to the late Maastrichtian age of the late Cretaceous period, 69 to 66 million years ago, with isolated specimens possibly indicating an earlier origin in the middle Campanian age. It was one of the last known members of the tyrannosaurids and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. The leg press is a compound weight training exercise in which the individual pushes a weight or resistance away from them using their legs. The term leg press machine refers to the apparatus used to perform this exercise.[1] The leg press can be used to evaluate an athlete's overall lower body strength (from the gluteus Maximus to the lower leg muscles). It can help to build squat strength.[2] If performed correctly, the inclined leg press can help build knees that can handle heavier free weights,[3] on the other hand, it also carries a risk of serious damage since locked knees can bend the wrong direction throughout the exercise. #trex #dino #paleontology #gym #lifting - @sphere_tosolemn
