Tyrannosaurus rex (Tyrant lizard king) or T. rex, is a large carnivorous dinosaur from North America. It is an adoptable animal in Zoo Tycoon and Zoo Tycoon 2.
Description
Perhaps the most famous dinosaur of all time, Tyrannosaurus rex was one of the largest theropods, a group of largely carnivorous dinosaurs. One of the largest specimens, nicknamed "Sue", was 12.8m (42ft) long and may have weighed up to 14 tonnes. Tyrannosaurus rex and other close relatives featured extremely powerful jaws capable of crushing bone and extremely acute senses of sight and smell, making them effective predators. Despite its large size, Tyrannosaurus rex is more closely related to smaller theropods like Velociraptor than to comparable-sized dinosaurs like Allosaurus. While it has sometimes been depicted with a covering of protofeathers, skin impressions suggest that most of its body was covered in scales.
Tyrannosaurus rex lived during the Cretaceous period across what is now western North America. It would have hunted a wide variety of other dinosaurs, including hadrosaurs, as evidenced by bones showing healed wounds from a tyrannosaur attack. Its long and powerful back legs suggest it was a fast runner across short distances, and its tiny arms were surprisingly powerful for their size. Evidence suggests that Tyrannosaurus rex may have hunted in packs. It was one of the last known non-avian dinosaurs to exist, living 66 million years ago until being wiped out by the Cretaceous-Paleogene Extinction Event.
Zoo Tycoon
Tyrannosaurus rex is an adoptable animal in Zoo Tycoon and was made available as part of the Zoo Tycoon: Dinosaur Digs expansion pack. It must be researched in order to be adopted. Additional research can be gained in order to make them more comfortable in their enclosure. Each individual costs $6,500.
Tyrannosaurus rex is a Grassland animal, but also requires gray stone and fresh water in its exhibit. Its favorite foliage is the Monkey Puzzle tree, but also likes the Broadleaf Bush. Like all large theropods, it uses the Dinosaur Cave shelter. Like all large theropods, Tyrannosaurus rex will break out of any non-electrified fence. Notably, it is the first animal in the Zoo Tycoon series capable of killing guests.

| The 'Tyrant lizard king' or Tyrannosaurus Rex really lives up to its name. It is one of the largest and fiercest of the carnivorous dinosaurs. In the wild, Tyrannosaurus Rex hunts herds of herbivorous dinosaurs through humid, semi-tropical forests.
The adult Tyrannosaurus Rex is 40 feet long and 15 feet high, and its prey is often many times larger. It can use its massive jaw and six inch replaceable teeth to bring down even the plated stegosaurus. Although its short arms (roughly three feet in length) are not particularly useful in a battle, the Tyrannosaurus Rex can bring down its prey with one huge bite. It allows its prey to weaken or bleed to death before consuming it in giant 500 pound mouthfulls. In addition to hunting the weak members of dinosaur herds, Tyrannosaurus Rex has also been known to scavenge meals. A combination of sharp eyesight and a strong sense of smell allows these massive carnivores to locate the remnants of other's kills. Tyrannosaurus Rex makes an especially good scavenger since no other dinosaur is likely to challege its right to share the bounty of a fresh kill. Tyrannosaurus Rex is built for long distance travel, and can range over a large area in search of food. Its massive legs end in two-toed feet, and its stiff tail is used for balance. No one knows how fast a Tyrannosaurs Rex can run when it is truly in a hurry, but many guess that these creatures can travel upwards of 50mph. They seldom maintain those speeds for long, as their massive size and weight means that a fall could be fatal. Unlike the herbivores they make their meals of, Tyrannosaurus Rex do not travel in herds. In fact, adults will often battle each other, sometimes to the death. Many Tyrannosaurus Rex carry the scars and wounds from these battles for their entire lives. In captivity, a hungry Tyrannosaurus Rex often will eat domestic herd animals such goats and sheep if it is unable to obtain its normal diet of stegosaurus meat. But this fearsome animal will kill and consume almost any creature that is unfortunate enough to wander into its habitat. It may even even consume the occasional guest who gets a little too close. Zookeepers, beware. |
Zoo Tycoon 2
Tyrannosaurus rex is an adoptable animal in Zoo Tycoon 2 and was added as part of the Dino Danger Pack. In Campaign and Challenge Mode, it is available for adoption when a zoo reaches a rating of 5 stars. Each individual costs $80,000.
Tyrannosaurus rex is a Tropical Rainforest animal, although it will tolerate Grassland. Like the other dinosaurs introduced in the pack, it will use the Dinosaur Prey Dummy to enrich itself and will make a nest to lay its eggs in.
Tyrannosaurus rex is also available in the Extinct Animals expansion pack. If the Dino Danger Pack has already been installed, it is updated to match the other dinosaurs with a more streamlined model and new textures, going from green in males and brown in females to striped gray in males and a faded green in females.

Dino Danger PackTyrannosaurus rex was a large, two-legged, meat-eating dinosaur that lived in the late Cretaceous Period, 65 million years ago. Scientists know more about Tyrannosaurus than any other predatory dinosaur. Tyrannosaurus had a bone-crushing bite and often preyed upon plant-eating dinosaurs, and its stomach could hold more than half a metric ton of meat. The frill of a Triceratops was found in the fossilized dung of a Tyrannosaurus. Extinct AnimalsThe Tyrannosaurus had an immense head, rows of terrifying, pointed teeth, and a bone-crushing bite. In fact, it was one of the biggest land-based carnivores that ever lived, and had an appetite to match: Its stomach could hold more than half a metric ton of meat. Need proof that Tyrannosaurus rex preyed upon plant-eating dinosaurs? The frill of a Triceratops was found in the fossilized dung of a Tyrannosaurus. But questions still remain: Scientists still don’t know how fast this giant beast moved, or whether it was primarily a scavenger or a predator. |

| Tyrannosaurus is the name of a genus (group) of large, two-legged, meat-eating dinosaurs that lived in the late Cretaceous Period, about 65 million years ago. The name Tyrannosaurus is derived from the Greek words tyrannos, "tyrant," and sauros, "lizard." Instantly recognizable by their size, upright posture, serrated (jagged) teeth, and small, two-fingered forelimbs, Tyrannosaurus were some of the largest meat-eating land animals that ever existed.
Tyrannosaurus are members of the family Tyrannosauridae, in the suborder Theropoda. Although scientists disagree about the number of species in the genus Tyrannosaurus, some scientists recognize four species, of which Tyrannosaurus rex is the best known. Tyrannosaurus were among the largest flesh-eating terrestrial animals, exceeded in size only by the Giganotosaurus and Carcharodontosaurus. They reached 12.5 m (41 ft) in length and 5 m (16 ft) in height, and they weighed over 5 metric tons. The skull of a Tyrannosaurus was large and flexible and contained a brain comparable in size to those of modern reptiles. Its bone-crushing bite was probably more powerful than that of any other flesh-eating dinosaur. The bridge of the nose contained wartlike knobs and pits. The animals had a broad field of vision but could focus their eyes directly to the front. A Tyrannosaurus had short arms with few nerves running through them. This limited nerve development suggests that the arm movements must have been unwieldy and clumsy. The barrel-shaped chest of these dinosaurs indicates that the lungs were very large. A latticework of bones protected the stomach and other internal organs. The legs were long and slender. Tyrannosaurus probably preferred open terrain, such as broad game trails and open forests, where it could move its large body and see unimpeded by brush. Scientists estimate that Tyrannosaurus could walk rapidly and may have been able to run at speeds up to 40 km/h (25 mph) when chasing prey. They also could lie in ambush upon a strong pelvic extension, with chin on the ground, watching for prey with their high-placed eyes. Scientists debate whether Tyrannosaurus were warm-blooded like modern mammals. Evidence suggests that the creatures had a uniform body temperature, which would require a metabolic rate higher than that of other reptiles. Some scientists have even suggested that Tyrannosaurus had feathers, not for flying but for insulation. A higher body temperature would require Tyrannosaurus to eat more often than other reptiles. The stomach of the dinosaur could hold more than half a metric ton of flesh, which would be consumed every few weeks. Scientists have found a 2-liter (2.1-qt) lump of fossilized dung that contains direct evidence of the prey of Tyrannosaurus: partly digested bone fragments of young plant-eating dinosaurs. Further evidence of their diet includes a Triceratops pelvis that exhibits deep punctures and grooves made by Tyrannosaurus teeth. Like most active carnivores, Tyrannosaurus probably also fed on the decaying bodies of dinosaurs killed by starvation and floods. Tooth marks on some Tyrannosaurus skulls indicate that the animals fought with one another by biting on the face. Fun Facts

Trivia
- The Tyrannosaurus rex roar in the first game uses stock sound effects, which are used in other video games such as Dino Crisis and Carnivores.
- The Extinct Animals render uses the young texture on the female Tyrannosaurus rex model, as opposed to the proper, dark texture. This quirk is also noticeable on the wildebeest.
- The Tyrannosaurus rex's render from its Hints and Tips page is the same render used in the Zoo Tycoon Card Flip game.
- Like the Carnotaurus, the Tyrannosaurus rex has a reversed sexual dimorphism compared to most other animals with the female being larger than the male. While this reflected current scientific research at the time of development, there is currently no unambiguous evidence for sexual dimorphism in any extinct dinosaur.
- Tyrannosaurus rex is the only animal capable of killing zoo guests in both Zoo Tycoon and Zoo Tycoon 2. In the latter game, only it and Carnotaurus are capable of doing so.
