Tyrannosaurus V3 (SciiFii)

***Tyrannosaurus rex americanum*** (name meaning "American tyrant lizard king") is a subspecies of *Tyrannosaurus rex*, a species of large carnivorous non-avian coelurosaurian theropod dinosaur. *Tyrannosaurus rex americanum* originally lived throughout what is now western North America, on what was then an island continent known as Laramidia, as an extinct *Tyrannosaurus rex* subspecies, but has since been brought back from extinction by SciiFii, using some DNA contained in some preserved soft tissue and using genetic engineering, and, unlike SciiFii's first two *Tyrannosaurus rex* subspecies, has been deliberately introduced throughout the modern wetlands, forests, open woodlands, grasslands, and open shrublands across North America to help boost biodiversity. Like other tyrannosaurids, *Tyrannosaurus rex americanum* is a bipedal brown-colored carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, Tyrannosaurus rex sciifii forelimbs are short but unusually powerful for their size and have two clawed digits. The largest specimens measures up to 12.3 metres (40 feet) in length, though *T. rex americanum* can grow to lengths of more than 12.3 metres (40 feet), up to 3.66 metres (12 feet) tall at the hips, and can weigh around 8.4 metric tons (9.3 short tons) to 14 metric tons (15.4 short tons). Although other theropods rival or exceed *Tyrannosaurus rex americanum* in size, it is still among the largest known land predators and has the strongest bite force among all terrestrial animals. By far the largest carnivore in its environment, *Tyrannosaurus rex americanum* is an apex predator and it preys upon hadrosaurs, armored herbivores like ceratopsians and ankylosaurs, and small-to-medium-sized sauropods when it first lived during the Late Cretaceous, although it is also a scavenger and can steal kills from *Acrocanthosaurus*, *Metriacanthosaurus*, bears, big cats, wolves, and other terrestrial predators. Despite being a predator, *Tyrannosaurus rex americanum* does not prey on mammals or any sapient species, most likely due to genetic manipulation from SciiFii's scientists during the subspecies' (re)creation, and is instead considered a gentle giant towards mammals (including humans) and non-mammal sapient species. It has some loose feathers that cover the top of its head, neck, and on the tip of its tail, likely the ancestral features it retained from the ancestors of large tyrannosaurids such as *Tyrannosaurus rex americanum*. It has gray eyebrow ridges when fully grown, which indicates a healthy individual. In contrary to myths and popular media, *Tyrannosaurus rex americanum* does not roar, but makes slight growls similar to that of alligators and booms similar to that to bitterns. *Tyrannosaurus rex americanum* can live to be around 28-30 years old and are social pack hunters, usually consisting of family members, that consists of up to 7 individual. During the mating season, the males fight over other males, until one male is injured (which can lead to a lost arm or two) or simply gives up, the winning male gets a right to mate. The eggs are laid around 3 months after the mating seasons, the eggs then hatch around 4-5 months after that, and the *Tyrannosaurus rex americanum* chicks are cared for by their parents, sometimes the chicks cannibalizes other chicks, until they are almost fully grown, when they must fend for themselves. The conservation status of *Tyrannosaurus rex americanum* is **Least Concern** due to successful conservation efforts and the animal's wide range.
