Paleontologists have unearthed the largest Tyrannosaurus rex fossil ever discovered, researchers say.

The massive predator, nicknamed “Scotty,” was about 42 feet long and likely weighed more than 9.7 tons, according to the study published last week in the peer-reviewed journal The Anatomical Record. Not only is the massive specimen the biggest T. rex ever found, it’s also larger than all other carnivorous dinosaurs.

“This is the rex of rexes,” said study author W. Scott Persons in a news release. “There is considerable size variability among Tyrannosaurus. Some individuals were lankier than others and some were more robust. Scotty exemplifies the robust.”

The fossil was nicknamed after a celebratory bottle of scotch opened the night it was discovered in Canada. Although the bones were found in 1991, it took more than a decade to excavate them from the surrounding hard sandstone.
