" Scotty: The Dinosaur Skeleton Which is a Contender for the Largest T. Rex Ever ?

In March 2019, a Tyrannosaurus rex made headlines 66 million years after it had died. Was its skeleton the largest of its kind ever discovered?
"Scotty", the skeleton had been discovered in Saskatchewan, Canada. In fact, these bones had been unearthed decades before. They were found in 1991, by then-school teacher Robert Gebhardt, but were so deeply encased in sandstone that it has taken decades to painstakingly remove them.
Until now, the largest T. rex skeleton known to science was that of "Sue". It was uncovered in South Dakota, USA, on 12 August 1990, by explorer and fossil collector Sue Hendrickson, after whom it was named.

So how do Scotty and Sue size up?

Unfortunately, it's practically impossible to make a direct comparison, as the two specimens are not equally whole. Sue is approximately 90% complete, compared to 65% for Scotty – indeed, Sue is the most complete T. rex skeleton – comprising 250 of the 380 bones that the body would have featured. That also makes it possible to calculate this dinosaur's original size – 12.5 m (41 ft) long and 4 m (13 ft) tall at the hip – fairly precisely.
From what we can tell, Scotty was probably slightly longer – perhaps up to 13 m (42 ft 7 in), according to the University of Alberta's Dr W Scott Persons, who led a study into calculating Scotty's dimensions.
But scientists always allow a margin of error when comparing such ancient skeletons. "
