Southwest Saskatchewan might not be the place you think of when it comes to world record holders, but a local in Scotty the T. rex was announced as the worlds largest Tyrannosaurus rex ever discovered.

Scotty, whose gender is not known, already owns two records as it is the largest dinosaur skeleton found in Canada and the oldest Tyrannosaurus rex to be found with estimations that it was 30-years-old before it passed away about 66 million years ago.

Robert Gebhardt who discovered Scotty in 1991 when exploring with two paleontologists Tim Tokaryk and John Storer from Regina, said he would never believe in his wildest dreams that he would discover a dinosaur, let alone the world's largest T. rex.

"It's an inward smile as well as an outward smile," he said. "It's nice to have been a part of something that has been going on since 1991."

Gebhardt who is a retired high school teacher in Eastend said that he just went out with Tokaryk and Storer to remove some microfossils when they uncovered something much larger.

"There was a little hill that contained various little fossilized bones. We bagged up that and we took that back to the vehicle and then in the afternoon decided to do some exploration and we just sort of separated a bit and went wandering around and that's when I came upon this vertebrate and a bit of a tooth. I really didn't know what I found so I had to do a bit of yelling to get the other two individuals back."

Phillip Currie, Gregory Erickson, and Scott Persons recently published evidence in 'The Anatomical Record'  to support Scotty being the largest Tyrannosaurus rex ever discovered.

Persons, a postdoctoral researcher at the University of Alberta Department of Biological Sciences, said that they were comparing Scotty to another T. rex, Chicago's Sue. Sue was thought to be the largest T. rex but was edged out by the Eastend discovery.

"Scotty and Sue are very, very similar in their overall proportions and very, very, similar in size," Persons said. "In the majority of measurements of the skeletal pieces that have been persevered for Scotty. Scott does inch Sue out by just a bit. Based on our math estimations about 400 kilograms on Sue."

Persons added that 400 kilograms is a lot in human standards but not for dinosaurs.

"It's just a simple matter of taking measurements on the same bone," he said. "We looked at things like the length of hip. We looked at things like the width of the shoulder girdle, the proportion of the leg bone and those in terms of length and in terms of girth."

Persons added that to reduce error, all of the measurements were taken by Phillip Currie and that measuring the bones was just one comparison that they were interested in using to compare Scotty.

"We are also interested in comparing Scotty to other large carnivorous dinosaurs and to all other Tyrannarous rex specimens that we know of," he said. "When it comes to actually just making comparisons between to Tyrannasaurs versus trying to come up with an absolute body mass, to do the latter what we do is a measurement of the girth of the femur. The greater the cross-sectional area the femur has the more weight is probably adapted to support so that is one primary way for getting the mass estimate of Scotty which is around 8,800 kilogram."

The near 9,000 kilograms would put Scotty weighing in as much as an African elephant which can weight between 6,000 to 10,000 kilograms.

Persons added that as somebody from Canada, it's very cool to see Canada have the world's largest king of the dinosaurs.

The report also found that Scotty had a bunch of injuries such as broken ribs, an infected jaw, and compressed vertebrae in its tail.
