Paleontologists have reported that a Tyrannosaurus rex unearthed in Canada – nicknamed “Scotty” – is the world’s largest so far, at 43 feet (13 meters) long.

Scotty, the researchers say, lived in prehistoric Saskatchewan, Canada, 66 million years ago. University of Alberta researcher Scott Persons is the lead author of the study, published March 21, 2019 in The Anatomical Record. Persons said in a statement:

Take careful measurements of its legs, hips, and even shoulder, and Scotty comes out a bit heftier than other T. rex specimens.

The skeleton was first discovered in 1991. But the hard sandstone that encased the bones took more than a decade to remove. Scientists have only recently been able to study the skeleton fully-assembled and realize how unique a dinosaur Scotty is.
