Tyrannosaurus rex (name meaning "Tyrant lizard king") was a species of large theropod dinosaur that lived during the late Cretaceous period.

Portrayal in the seriesEdit

Tyrannosaurus was a very large and heavy dinosaur that could often hunt in packs of around three, rarely five individuals. However, if one pack member was mortally wounded during a hunt, the others would abandon them to their fate, meaning the hunt was too heavy for them. Tyrannosaurus were relatively fast and agile animals who were capable of catching fast moving prey including Ornithomimus, but were also capable in tackling large and sturdy dinosaurs like Triceratops (PP: T-Rex Returns).

Female Tyrannosaurus were highly protective of their offspring and would find food for them even if it costed her her life. She would even fight off other members of her species in order to protect her young, even if she was wounded. (PP: T-Rex Returns)

Tyrannosaurus siblings were extremely hostile towards each other. When juvenile, siblings would commonly play-fight. (PP: T-Rex Returns) However, when sub-adult to adult, siblings would become extremely aggressive and would often fight. It was common for siblings to kill the other.  Tyrannosaurus bites could cause infections and diseases like septicemia. (PP: The Bug House)

T. rexes hated water, and wouldn't go near it, except for drink or other necessities(PP: T-Rex Returns). If 2 Tyrannosaurus rex were in a zoo and fight, you could separate them with a hose! (PP: Dinobirds)

In Prehistoric ParkEdit

T-Rex ReturnsEdit

After triggering an Ornithomimus stampede, a trio of Tyrannosaurus rex was seen confronting Nigel Marven in a forest. As Nigel bolted, the T. rex followed him. Nigel narrowly escaped by climbing through a fallen branch, disabling the carnivores from following. As Nigel ventured further into the dense vegetation, the Tyrannosaurus eventually left.

The following day, Nigel entered a volcanic ash field littered with footprints. As he followed the trail, he discovered a family of Tyrannosaurus. As he and the cameraman hid behind some rocks, they observed their family behaviors, including the younger males play fighting. After a period of time, the pack left. As soon as they left, Nigel looked for eggs amongst the bones littered haphazardly around the territory. Unfortunately, all the eggs he found were empty.

The next day, the Tyrannosaurus pack from the day before arrived at the river a large herd of Triceratops were living by. As the Tyrannosaurus launched the attack, the Triceratops scattered. As the other T. rex caused havoc within the herd, one female managed to catch a baby Triceratops. However, another herd member gored the female with its horns. As the female roared in agony, the other pack members ran off. The injured female Tyrannosaurus then spotted another Triceratops hiding in the bushes. Nigel stepped in and set up the time portal to Prehistoric Park and attempted to lure the Triceratops and the female Tyrannosaurus through. To Nigel's dismay, only the Triceratops followed. The female T. rex remained in the Cretaceous.

When Nigel returned to the Cretaceous, he found the female Tyrannosaurus by a river. Nigel and the cameraman hid from her as she watched the corpse of a young Triceratops float down the river. As she ventured closer to the carcass, she could not reach it as her leg injury handicapped her. After realising that trying to retrieve the carrion was a lost cause, she left the river.

Later, after causing a flock of Ornithomimus to flee in panic, the female Tyrannosaurus chased them into the location where Nigel and his team were building a giant wall to help aid them into making the female enter the time portal and into Prehistoric Park. As most of the Ornithomimus flock bolted through the time portal, one slower individual failed to outrun the crippled Tyrannosaurus and was caught. The female then left with the Ornithomimus corpse. Nigel followed.

Nigel followed the female Tyrannosaurus into her territory before discovering that she was saving the Ornithomimus for her two offspring. As the mother prepared to feed her young, a male Tyrannosaurus confronted her and challenged her for the corpse. The mother's young watched as their mother fought the male Tyrannosaurus. Despite her injury, the female Tyrannosaurus put up a ferocious fight, but was ultimately slain by the male. Then, the male picked up the Ornithomimus corpse and left. As Nigel approached the now-orphaned chicks, the mother gave one last roar at Nigel before finally passing away.

Subsequently, the asteroid marking the K-T boundary extinction event entered the Earth's atmosphere and collided with Earth. Immediately afterwards, as the blast front approached them, Nigel quickly tempted the young Tyrannosaurus through the time portal, using himself as bait. Narrowly escaping the blast front, Nigel and the Tyrannosaurus siblings arrived at Prehistoric Park. The undernourished pair were then fed.

Later, the Tyrannosaurus pair were transported to T. rex Hill, their new enclosure. Nigel, Bob Arthur and Suzanne McNabb visited them where Nigel named them Terrence and Matilda

A Mammoth UndertakingEdit

Bob Arthur and his team were trying to crane a slab of meat over the Tyrannosaurus pen in order to feed Terrence and Matilda. Whilst the food dangled in mid air, Terrence and Matilda frequently tried to reach it. When they released the meat, the pair fought over the food, with Matilda dragging it away. Later, when feeding time came and Martha the Mammoth wasn't eating, the T. rexes were eating flesh again and putting on more weight.  

DinobirdsEdit

Terrence and Matilda were beginning to get on each other's nerves and they began fighting. Bob Arthur managed to break up the fight by spraying twenty gallons of water at the Tyrannosaurus. Whilst separate enclosures were being built, they were both kept in separate holding pens.

Saving the SabretoothEdit

Terrence and Matilda were being moved into their previous enclosure but with a wall separating them. When Terrence was moved into his half, he was greeted by Matilda with a hostile lunge.

At the end of the episode, Nigel Marven, Bob Arthur and the two Ornithomimus chicks that imprinted on him visited Matilda in her enclosure. The two chicks wandered into her enclosure but were chased out by her.

The Bug HouseEdit

1x5 MatildaAboutToKillTerrence

Matilda broke into Terrence's half of the enclosure and challenged him for it. As Bob Arthur set up a gun in an attempt to tranquilize her, Matilda wounded and nearly killed Terrence but Nigel Marven entered the enclosure in a jeep and used himself as bait. Matilda couldn't resist a moving target and chased Nigel's jeep. As Matilda gained, Nigel stopped the jeep and climbed up a tree where Matilda then succumbed to the tranquilizer dart. Terence was sent to get healed in the end, while Matilda may have been put back into her half of the enclosure (with the gate possibly repaired).

On the operating table, Suzanne McNabb attempted to stitch up a gash of Terrence's face caused by Matilda. The next twenty four hours were critical for Terrence. Later, Suzanne visited Terrence who was being kept in a holding pen. She noticed that the gash on his face was inflamed and infected. She performed a blood test on Terrence and the results were that he had septicemia. Not knowing how it would react on a dinosaur, Suzanne injected him with antibiotics.

When Nigel came back from the Carboniferous, he and Suzanne found out that Terrence had awoken and was trashing Suzanne's surgery. Terrence was later moved back to his enclosure where he was set to make a full recovery.

SupercrocEdit

1x6 MatildaEscapesDeinosuchus

During the Mass Break-Out, one of Prehistoric Park's Titanosaurs broke into Matilda's enclosure, allowing Matilda to escape. Matilda made her way to Mammoth Mount where she separated the baby African elephant from everyone in its herd except from Martha. Martha intervened and defended the baby elephant from Matilda until Nigel Marven used himself as bait and made Matilda pursue him. Matilda chased Nigel past Henry and the other Nile Crocodiles and past Deinosuchus Dip where the resident Deinosuchus attacked Matilda. Nigel ran to one of the holding pens and climbed the ladder, narrowly escaping Matilda. Nigel then managed to catch Matilda by locking her in one of the holding pens. Matilda as well as the other feral park residents were returned to their enclosures.

Behind the scenesEdit

  • Tyrannosaurus rex is the most famous dinosaur of all time.
  • The names, Terrence and Matlida, were inspired by Nigel's parents.
  • During the Mass Break-Out, the original plan was for Matlida to be smaller, and for her to jump on Martha's head, before Nigel threw a stone at her, causing her to chase him.

ErrorsEdit

  • In Supercroc, a panicking Titanosaur broke through the fence to Terrence's side of T. rex Hill, but Matilda was the Tyrannosaurus who escaped. It is possible that Terence may have broke out but was never featured or mentioned. The Titanosaur may have broken the fence of Matilda too.
  • The narrator said T. rex could run 40 mph when they need to, but their correct speed is only in between 15-25 mph. However, young T. rexes could have run close to 40 mph. 
  • They are depicted featherless. In reality, adults may have had feathers and chicks almost certainly possessed them.
  • T. rex is depicted as being 5 tons, but specimens 7-8 tons are not uncommon.
  • Evidence that females were bigger than males isn't solid anymore.
  • It needs lips covering its' teeth.
  • T. rex is depicted as hating water, however evidence suggests that T. rex, despite their minuscule arms, were excellent swimmers, although it's still debated at this point.
  • The T. rex was much less bulky than it would have been in real life.
  • Nigel mentions that T. rexes get injured badly when they fall over. Later in the series however, Matilda is tranquilized and falls over with no negative side effects. It is likely that the side effects would only be major if the T. rex is fully grown or if he falls chest-first, as it's sternum is very fragile.
  • T. rexes are seen hunting in groups, despite there are no solid evidences that they did that.
  • In the series, T. rexes are treated like many other modern reptiles, such as lizards and crocodiles. The correct inferrence is that keepers should treat them like birds, as they are close relatives.
  • Nigel Marven goes rescuing the T. rex 65 million years ago, while they actually went extinct 66 million years ago.
