Tyrannosaurus

***Tyrannosaurus*** are a genus of theropod dinosaur that appear in The Lion Guard: New Beginning universe. They live in the Pride Lands.

## Appearance

Tyrannosaurus rex were large with small but strong two fingered arms, equipped with sharp & sickle-shaped claws. But recent studies show that t-rexes were indeed scaly skinned & there skins were similar to those of crocodilians. But they may have been mostly scaly skinned with hair-like feathers covering parts of the body. Most t-rexes grow 12 meters long but some would have reached 13 meters in length. A t-rex’s skull is huge & it’s snout & lower jaw were very deep. The whole mouth was massive and contained 60 serrated teeth, all them were different sizes with some up 20cm long. A tyrannosaur’s body was heavily built & it’s cavity was wide, to improve its mobility some of it’s vertebrae had holes that can help reduce weight to the animal. The hind legs of a t-rex were large & muscular which were connected to the body via a lizard-hip arrangement, the size of the legs would have gave the dinosaur an excellent pushing power. But due to it’s size & small strides it couldn’t have run too fast ( compared to other theropod-type Dinosaurs). The tail of a t-rex was used to balance is body horizontally & essential for chasing down prey.

## Information

Tyrannosaurus rex was one of the largest of the theropod dinosaurs and easily the largest predator in its environment. It had a massive skull with reinforced banana-like teeth. Recent studies have estimated that *T. rex* was capable of biting down with 64,000 N (over 6 tonnes) of force, making it one of the most powerful bites ever known. This amount of force was capable of not only piercing, but completely shattering bone and armor, which would explain why its teeth were so robust, reinforced, and relatively blunt, used for attacking large prey, and crushing smaller prey like Ornithomimids. It likely formed such devastating features in order to prey on well-defended herbivores such as the three-horned *Triceratops* and *Torosaurus*, which would in turn evolve more defenses and make a vicious cycle of an evolutionary arm's race. While it was originally hypothesized that *T. rex* might have had flexible parts of its skull like modern relatives such as parrots and lizards, recent studies involving 3D imaging compared stresses on its head revealed that the bones in its skull would instead have been fused like a crocodile in order to reinforce it and keep it from breaking apart due to the massive amount of force its jaws could deliver.

In life *Tyrannosaurus* would have had eyes the size of softballs and were capable of seeing long distances with very good depth due to them being forward-facing, giving it binocular vision. CAT-Scans of the skull have revealed that much of the brain was dedicated to its sense of smell, giving *T. rex* one of the strongest senses known in any modern or extinct taxa. The structure of bones around its ear would have been well suited to picking up low-frequency sounds like modern-day elephants do, indicating that *T. rex* and its prey were making deep low-frequency noises. Because *Tyrannosaurus* lacked a larynx like modern mammals such as lions and even likely lacked a syrinx such as those found in modern birds, it is unlikely that it was capable of roaring in a traditional sense as is often depicted in pop culture. Instead, it is believed that *T. rex* would have done low, deep rumblings and hisses, along with the occasional bellows and "roars" similar to living crocodiles.

## Sociocultural characteristics

Massive carnivores, the Tyrannosaurus roamed the land looking for prey, which they could kill with a single bone-crushing bite, though catching prey was more an issue of stealth than of speed, for Tyrannosaurus was not the fastest runner. Equipped with a head full of bone-crushing dagger-like teeth, strong hind legs, two small forearms with two fingers each and a long, thick tail for counterbalance, the Tyrannosaurus filled the role of dominant predator among many dinosaurs. Like other dinosaurs, Tyrannosaurus were egg-layers.

Mother Tyrannosaurus, such as Momma, tended to their young, which hatched from eggs that were about three feet high, by taking them to sources of heat such as Lava Falls upon hatching and bringing the youngsters either carrion or stunned or dead small dinosaurs so that the babies would learn to hunt.
