Some may suggest others but the most famous of all the dinosaurs is Tyrannosaurs Rex (meaning Tyrant Lizard, with the rex meaning king) or simply T. Rex for short. Though despite its famous reputation the T.Rex still has a lot of question marks surrounding it and many unanswered questions. 

Was it a lone hunter or pack hunter. If it even was a hunter and instead a scavenger. Then there is the debate did T.Rex have feathers like some Late Cretaceous Dinosaurs had, it’s potential speed, and to what sound its raw would of made, was it like that in the Jurassic park movies for instance or completely different entirely. Only with more research and hopefully possible new discoveries can answer these questions and many palaeontologist will no doubt be throwing around they theories and opinions. 


What is know and proven is that T. Rex was a furious predator and extremely powerful and with up to 60 teeth, which each one could grow up to 20cm (8 inches) long and bite around 3 times as powerful than that of a lion. Some fossil finds of bones from Triceratops and Edmontosaurus (herbivore dinosaurs and typical prey for the T.Rex) shows that Tyrannosaurs could crunch through bone, with bite marks found on the fossil bones and analysis of fossilised T.Rex coprolite (dung) showing that it contained the bones of its prey.

  

Found in Canada and the USA, and roaming the earth in the Late Cretaceous Period, 67-65 million years ago, the T.Rex could weigh up to 7000kg and growing up to 12 meters long (the equivalent of one and half buses).


The Tyrannosaurs skull could grow over 1.5 meters (5 feet) and the cavity that housed the part of the brain responsible for smell was relatively large and indicates that the T.Rex would of had good sense of smell to hunt it’s prey or locate dead bodies to scavenge.


The arms of the T.Rex are again open to debate too of they purpose with serval speculations being made. Though very small relative to overall body size, measuring only 1 meter (3.3 ft) long, studies of complete limbs found show the bones had a large areas for muscle attachment, indicating considerable strength.


Several notable Tyrannosaurus remains have been found in the Hell Creek Formation. During the Maastrichtian in the Late Cretaceous Period, this area was subtropical, with a warm and humid climate.


Since it was first described in 1905 Tyrannosaurs rex has become a dinosaur that everyone knows and through popular culture this has only enhanced that. Whether what the true nature of this species was, T.Rex will no doubt always be the King Of The Dinosaurs.
