The dreaded Tyrannosaurus rex and its dinosaur cousins were successful predators partly due to unique teeth designed like steak knives that allowed them to tear through the flesh of their prey, a new study has found.
Paleontologists have branded the new 'Jurassic World' flick a "dumb monster movie" for failing to include the latest discoveries about dinosaurs, mainly that the creatures were covered in fluffy - and possibly colourful - feathers.
The notorious carnivore Tyrannosaurus rex had a 'bizarre' vegetarian cousin with a tiny head, long neck and blunt fingers, according to scientists, who say the creature is proving to be an evolutionary jigsaw puzzle.
Researchers have explained that the 68-million-year-old soft tissue which was discovered from the bones of a Tyrannosaurus rex did not decay and survived millennia because of the iron content in the dinosaur`s body.
Palaeontologists on Friday announced they had uncovered the remains of one of the greatest land predators ever -- a nine-metre (30-foot) four-tonne dinosaur that stalked the planet 100 million years ago.
A lot of people mistakenly believe that Tyrannosaurus rex stood upright with its tail on the ground but in actuality they had a more bird-like posture, tail in the air and head pitched forward of its two massive legs.
