Saskatchewan Dug Up the Heaviest T. Rex Ever Found

On August 16, 1991, a school principal from Eastend, Saskatchewan spotted a bone sticking out of a dry channel in the Frenchman River Valley. He had only come along to watch two museum paleontologists work. That bone led to Scotty, declared in 2019 the heaviest Tyrannosaurus rex known to science at an estimated 8,870 kg (19,555 lb). That's about two and a half tons heavier than a bull African elephant, and nobody ever put it on a scale. This is the full story: a jaw found with its teeth still in it, a skull dragged out of the hills on a sled behind a tractor, and a weight worked out from one thigh bone 59 cm around. Then Chicago pushes back. The Field Museum calls Scotty and Sue statistically indistinguishable, and the claim that Scotty was the oldest T. rex gets overturned. Finally, inside one broken rib, two particle machines found something never before seen in a fossil. 👉 Heaviest T. rex ever found, or a tie with Sue?
