University of Alberta paleontologists have just reported the world's largest Tyrannosaurus rex and the largest dinosaur skeleton ever found in Canada. The 13 meter long T. rex nicknamed "Scotty", lived 66 million years ago in prehistoric Saskatchewan.
"This is the rex of rexes," said Scott Persons, lead author of the study and postdoctoral fellow in the Department of Biological Sciences. "There are significant size differences among Tyrannosaurus, some individuals were more boring than others and others were more robust, Scotty is an example of robustness, take careful measurements of the legs, hips, and even the shoulder." Scotty is a little heavier than others T. rex copies. "
Scotty, who was nicknamed a festive bottle of scotch the night he was discovered, has leg bones that indicate a live weight of more than 8,800 kg, making him taller Do as any other carnivorous dinosaur. The scientific work on Scotty was a correspondingly massive project.
The skeleton was first discovered in 1
It's not just the size and weight of Scotty that sets it apart. The Canadian Mega Rex also claims higher seniority.
"Scotty is the oldest T. rex ," explains Persons. "By which I mean it had the most candles on its last birthday cake, you can get an idea of how old a dinosaur is by cutting into its bones and examining its growth patterns." Scotty is all old growth. "  But the age is relative and T. rex it grew fast and died young. It was estimated that Scotty was only in his early 30s when he died.
"According to Tyrannosaurus standards, he had an unusually long life and it was a violent one," said Persons. "Shaking the skeleton are pathologies – places where scarred bones record large injuries."
Scotty's injuries include broken ribs, an infected jaw and possibly a bite from another. T. rex on his tail – scars from a long life struggle.
"I think more and more discoveries will be made," said Persons. "But right now, this Tyrannosaurus is the largest terrestrial predator. Science is well known."
In May 2019, a new Scotty Skeleton exhibit opens at the Royal Saskatchewan Museum.
