'''Tyrannosaurus rex''' were one of the most famous [[dinosaur]] [[species]] on [[Earth]]. They were also known as the '''''T. rex''''', or '''king tyrant lizard'''.

The Tyrannosaurus rex was one of the largest [[Therapod]] [[carnivore]]s, [[measuring]] up to [[13 (number)|13]] [[metre]]s in [[length]] with [[teeth]] the [[size]] of [[dagger]]s. Some [[Tyrannosaur]] tooth [[fossil]]s were up to [[30 (number)|30]] [[centimetre]]s long; the teeth were designed to rend and [[tear]] the [[monster]]'s [[prey]]. Some [[scientist]]s believed that T-Rex was a [[scavenger]], but the balance of [[evidence]] later suggested that it was an [[apex predator]], a [[hunter]] which chased down big [[Sauropod]]s, which were the size of a [[school bus]] and themselves known as the [[lion]] of the [[Cretaceous period]].

'''Tyrannosaurus rex''' (meaning ''tyrant lizard king'') is one of the most famous [[dinosaur]]s. ''Tyrannosaurus rex'' hails from [[Earth]], specifically what is now western [[North America]]. They lived towards the end of the [[Distant past|Cretaceous]].

Tyrannosaurus rex

Tyrannosaurus rex were one of the most famous dinosaur species on Earth. They were also known as the T. rex, or king tyrant lizard. (AUDIO: The World Traders [+]Loading...["The World Traders (audio story)"]) Recognised as the "king of the dinosaurs", it was perhaps the best known of all dinosaurs.

Biology[[edit] | [edit source]]

The Tyrannosaurus rex was one of the largest Therapod carnivores, measuring up to 13 metres in length with teeth the size of daggers. Some Tyrannosaur tooth fossils were up to 30 centimetres long; the teeth were designed to rend and tear the monster's prey. Some scientists believed that T-Rex was a scavenger, but the balance of evidence later suggested that it was an apex predator, a hunter which chased down big Sauropods, which were the size of a school bus and themselves known as the lion of the Cretaceous period.

Behind the scenes[[edit] | [edit source]]

  • Many reference sources identify the Theropod Silurian pet from TV: Doctor Who and the Silurians as a T. rex. However, whilst this is indeed the case in the novelisation, it is very unlikely going by televised evidence, since the Doctor claims not to recognise the species, the implication there being that the species is one bred or engineered by the Silurians, which would mean whatever species it may be would not exist in the real world.
  • The T. rex is amongst the most iconic of real-world Dinosaurs, explaining its prominent featuring in Doctor Who.
  • In real life, the T. rex existed in the Cretaceous period, however most DWU sources date it to the Jurassic.
  • The T. rex notably appeared in Episode 5.5 of Primeval. The profile provided in Prehistory Repeating Itself [+]Loading...["Prehistory Repeating Itself (feature)"] was, in fact, recycled from Cubicle Seven's Primeval game.
