Alberta confirms world’s biggest dinosaur graveyard
Site near Medicine Hat spurs new theory about why Alberta is so dinosaur-rich
A 2.3-square-kilometre site near Hilda, Alberta, is the biggest deposit of dinosaur bones ever found. The thousands of bones belonging to the Centrosaurus species were discovered in the 1990s, but scientists just now confirmed the size of the discovery. Geological data from the bone bed has also offered paleontologists a new explanation for why Alberta is so rich in dead dinos: 76 million years ago the area may have been prone to catastrophic tropical storms.
