Largest dinosaur skeleton found in Canada: Details inside
New Delhi : A fresh report from paleontologists claims that it has found the world's biggest Tyrannosaurus rex which is also the largest dinosaur skeleton ever found in Canada. The 13-metre-long T. rex, nicknamed 'Scotty,' lived in prehistoric Saskatchewan 66 million years ago.
Researchers in the University of Alberta have reported about the world's biggest Tyrannosaurus rex. "This is the rex of rexes," said Scott Persons, lead author of the study and postdoctoral researcher in the Department of Biological Sciences. "There is considerable size variability among Tyrannosaurus.
The largest ever dinosaur skeleton has been discovered with leg bones suggesting a living weight of more than 8,800 kg, making it bigger than all other carnivorous dinosaurs. The scientific work on Scotty has been a correspondingly massive project.
The skeleton was first discovered in 1991, when paleontologists including T. Rex Expert and UAlberta professor Phil Currie were called in on the project. But the hard sandstone that encased the bones took more than a decade to remove and only now have scientists been able to study Scotty fully-assembled and realize how unique a dinosaur it is.
"Scotty is the oldest T. rex known," Persons explains. "By which I mean, it would have 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 studying its growth patterns. Scotty is all old growth."
However, the age of this gigantic animal is relative and T. rexes grew fast and died young. Scotty was estimated to have only been in its early 30s when it died.
"By Tyrannosaurus standards, it had an unusually long life. And it was a violent one," Persons said. "Riddled across the skeleton are pathologies -- spots where scarred bone records large injuries."
Among Scotty's injures are broken ribs, an infected jaw, and on its tail.
"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 be launched at the Royal Saskatchewan Museum in May 2019.
