Rex found in Canada is biggest ever

Rex found in Canada is biggest ever

"Among the known species, T. rex is one of the best represented extinct dinosaurs, with more than 20 fossil individuals identified", according to National Geographic. (8,870 kilograms), or about as much as 6.5 Volkswagen Beetles, a new study finds.

Though the size difference between Scotty, Sue and other known Tyrannosaurus specimens may not be that significant-and certainly lies within the margin of error for calculating the weights of such prehistoric predators-Scotty still pushes the threshold of the maximum T. rex size higher than previously thought.

"By Tyrannosaurus standards, it had an unusually long life".

The record-breaking T-Rex was likely 42 feet long and may have weighed almost 10 tons.

It was first discovered in Saskatchewan near the United States border in 1991, but sandstone that had encased the skeleton took over a decade to remove.

The big predator lived about 66 million years ago, and despite having made it to a relatively old age, dying in its early 30s, researchers estimated it suffered some bumps and bruises along the way.


'Scotty, ' is a 66-million-year-old T-rex who was found in Canada back in 1991, and it's taken 28 years for him to be crowned as the undisputed king of kings when it comes to the Tyrannosaurus rex. "It would not surprise me that those animals turn out to increase the range of body size, potentially to overlap or even surpass what we know from T-Rex". The new research, led by paleontologist Scott Persons from the University of Alberta, was published in the journal The Anatomical Record. That means Scotty is the largest meat eating creature that has ever walked the earth.

It's probably no coincidence that Scotty was both enormous and long-lived: Roni Dengler of Discover magazine writes that the dearth of similarly sized T. rex fossils suggests most of the dinosaur's peers didn't survive long enough to reach their full potential.

Only when Scotty was completely unearthed and fully assembled were the researchers able to complete their investigation.

Size isn't Scotty's only claim to fame.

Living to a ripe, old age some 68 million years ago, Scotty's skeleton gives scientists insight into the life the dinosaur led. Scotty suffered "numerous severe injuries", including broken ribs, shattered tailbones and an infected jaw, according to the study.

Scotty will be on public display at the Royal Saskatchewan Museum in Regina, Saskatchewan, this May.
