Big dinosaurs are a thing, obviously. But when you’re standing in front of Scotty the T. rex, the scale of the thing hits you in a way that a Jurassic Park movie just can't. Most of us grew up thinking Sue, the famous specimen in Chicago, was the undisputed heavyweight champion of the dinosaur world. Well, times change. Paleontology is a messy, evolving science, and right now, Scotty is wearing the crown.
It’s not just about being long. It’s about being thick.
The bottle of scotch that started it all
Honestly, the name is the best part of the story. In August 1991, a high school teacher named Robert Gebhardt was out prospecting with a team from the Royal Saskatchewan Museum. They were trekking through the Frenchman River Valley in Saskatchewan—a place that, 66 million years ago, was basically a lush, humid coastal plain.
Gebhardt stumbled upon a piece of a tail vertebra and a chunk of a tooth. When the team realized they were looking at a massive Tyrannosaurus rex, they wanted to celebrate. The only thing they had on hand was a bottle of scotch. Naturally, the dinosaur became "Scotty."
It took forever to get the bones out. We're talking decades. The sandstone surrounding the skeleton was so hard it was like trying to chip a diamond out of a concrete sidewalk. Most of the excavation happened in the mid-90s, but it wasn't until 2019 that a team led by Dr. Scott Persons at the University of Alberta finally published the definitive measurements.
Why Scotty is basically an absolute unit
When paleontologists talk about "size," they usually mean mass. Length is cool, but weight is what tells you how an animal lived. Scotty is about 13 meters long (roughly 42.7 feet). That’s big, sure. But the real shocker is the weight estimate: 8,870 kilograms.

For those of us who don't speak metric, that’s about 19,555 pounds.
That makes Scotty roughly 5% heavier than Sue. It doesn't sound like a lot, but in biological terms, it's the difference between a heavyweight boxer and a super-heavyweight. Scotty has what scientists call "robust" proportions. His legs, hips, and shoulders are built like a tank. If Sue was a lean, mean hunting machine, Scotty was the brute-force equivalent.
A life of absolute carnage
Scotty didn't just get big by sitting around. This dinosaur was a survivor. When researchers looked at the bones, they found a literal map of a violent life.
- Broken ribs: Multiple fractures that had healed over time.
- Infected jaw: Evidence of a nasty bone infection.
- Tail injuries: Some of the vertebrae were damaged, possibly from a massive bite from another T. rex.
Basically, Scotty was a brawler.
The most fascinating part? Scotty was old. By cutting into the bones and looking at growth rings (much like a tree), Dr. Persons and his team determined that Scotty was likely in his early 30s when he died. In the "live fast, die young" world of the Cretaceous, 30 is ancient. Most T. rexes didn't make it out of their 20s.

The 2026 perspective: Preserved blood vessels?
One of the wildest things we’ve learned recently—and this is something that’s still blowing minds in the paleontology world as of late 2025—is the discovery of preserved structures inside Scotty's bones.
Jerit Mitchell, a researcher at the University of Regina, used synchrotron X-ray imaging to look inside a fractured rib bone. He found what appear to be preserved blood vessel structures. It turns out that when Scotty was healing from one of those many fights, the increased blood flow to the injury site might have helped "lock" those biological structures in place before they could completely decay.
It’s a game-changer. We aren't just looking at rocks shaped like bones anymore; we're looking at the actual plumbing of a 66-million-year-old predator.
Where you can actually see Scotty
If you want to see the "Rex of Rexes," you've got two main options in Saskatchewan.
- The T. rex Discovery Centre (Eastend): This is near the actual dig site. It’s a pilgrimage for dino-nerds.
- The Royal Saskatchewan Museum (Regina): They have a massive, world-class mount of Scotty that really lets you appreciate the girth of those leg bones.
Is Scotty definitely the biggest?
Let’s be real for a second. Paleontology is a game of "what have you found lately?"

While Scotty is currently the largest specimen we have a decent skeleton for (about 65% complete), computer models suggest that even bigger T. rexes probably existed. Some researchers believe there could have been individuals 70% larger than Scotty that we just haven't found yet.
But until someone digs up a bigger pile of bones, Scotty stays on the throne.
How to experience Scotty the T. rex for yourself
If you're planning a trip to see this prehistoric beast or just want to dive deeper into the science, here is what you should actually do:
- Check the season: The T. rex Discovery Centre in Eastend is usually a seasonal attraction (May through September). Don't just show up in December expecting the doors to be open; the Saskatchewan winter is no joke.
- Look for the "Pathologies": When you see the skeleton, look specifically at the ribs and the tail. You can see the lumps where the bone grew back after being broken. It makes the animal feel much more "real" than a clean museum cast.
- Read the source paper: If you’re a science geek, look up “An Older and Exceptionally Large Adult Specimen of Tyrannosaurus rex” in the journal The Anatomical Record (2019). It’s the paper that officially put Scotty on the map.
- Visit the Royal Saskatchewan Museum website: They often have 360-degree virtual tours of the CN T. rex Gallery if you can't make it to Regina in person.
Scotty reminds us that the world was once inhabited by monsters that weren't just fast and scary, but old, scarred, and incredibly resilient. Seeing the sheer mass of this skeleton changes how you think about the history of life on Earth.
