Real-world Information Edit
Arguably the most famous and most popular dinosaur of them all, Tyrannosaurus rex was a massive theropod that lived at the very end of the Late Cretaceous, around 67-66 million years ago, in what is now North America. Its Latin name means "tyrant lizard king". It grew about 12-13 metres in length, and an estimated 6 tons in weight.
Its skull measured around 1.5 metres (5 feet) in length. With a mouth full of teeth about the same size and shape as bananas, and a bite force of around 200000 newtons (about 20 tons), this carnivore was capable of crunching its way through bone as if it were cardboard. Its eyes faced forward, giving it binocular vision, and it also had one of the best senses of smell of any dinosaur.Healed bite wounds from T. rex found on ceratopsian and hadrosaur bones suggest that it was indeed a predator, that attacked and killed large prey. However, its sense of smell meant it could also find and scavenge carrion.
Tyrannosaurus led a violent lifestyle. Many of their skulls are covered in bites left by other members of their own species.
Studies of growth patterns in the bones show that T. rex grew at a slow but steady pace until the age of about 14 years, but entered a massive growth spurt at that age, reaching adult size by about the age of 18.
More than 50 specimens of Tyrannosaurus rex have been found, some of them with nearly complete skeletons.
It is currently unknown if T. rex had feathers or not. However, the discovery of feathers preserved on the distantly related Yutyrannus huali suggest that this is possible.
JP Information Edit
Tyrannosaurus rex is a must-have for any ambitious park, but be careful, as this animal is not to be taken lightly! This dinosaur is large, strong, notoriously bad-tempered, and requires huge quantities of meat on a regular basis. These animals are fiercely territorial and mostly solitary, but have sometimes been known to stick together in mated pairs. These pairs are closely bonded, and will not usually separate unless there's not enough prey around to support both partners.
In order to house a T. rex, you will need a very large territory with a mix of forest and open country, surrounded by thick reinforced stone walls, high-security electric fencing, or immensely reinforced steel barriers. Habitat enrichment (specifically, live prey) is also essential, as these relatively intelligent dinosaurs get bored easily.
These dinosaurs WILL NOT tolerate other large carnivores in their territory, not even of a different species, and should therefore NEVER be kept in multi-species large dinosaur exhibits! That being said, they will happily tolerate very small scavengers like Compsognathus and Ichthyornis, as they are too small to be considered prey.
In-game Information Edit
Tyrannosaurus is currently the largest and strongest carnivore in the mod, with health around 80 HP, and attack damage of around 20 HP. It'll tolerate being in pairs, but it will attack and try to kill any additional Tyrannosaurus that it detects nearby. It is not imprintable (see Taming), due to its short temper and aggressive lifestyle.
