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 in prehistoric Saskatchewan 66 million years ago
"This is the rex of rexes," said Scott Persons, lead author of the study and postdoctoral researcher in the Department of Biological Sciences. "Scotty is an example of the robust one, and he is a bit more heptile than others T. rex specimens. "
Scotty, nicknamed for a celebratory bottle of scotch the night it was discovered, has leg bones suggesting a living weight of more than 8,800 kg, making it bigger than all other carnivorous dinosaurs.
The skeleton was first discovered in 1
It is not just Scotty's size and weight that set it apart. The Canadian mega rex also lays claim to seniority.
"Scotty is the oldest T. rex known," Persons explains. "Scotty is all the old growth."
"It's a bigger candle than I have ever seen." ] But age is relative, and T. rex es grew fast and died young. Scotty was estimated to have only been in his early 30s when he died
"By Tyrannosaurus standards, it had an unusually long life." It was a violent one, "Persons said. "Riddled across the skeleton has pathogens – spots where scarred bone records large injuries."
Among Scotty's injuries are broken ribs, an infected jaw, and what may be a bite from another T. rex on his tail – battle scars from a long life
"I think there will always be bigger discoveries to be made," said Persons "But as of right now, this particular Tyrannosaurus is the largest terrestrial predator known to science. "
A new exhibition featuring the skeleton of Scotty is set to open at the Royal Saskatchewan Museum in May 2019.
