Dinosaur “Mega-bonebed” Near Alberta-Saskatchewan Border

Live Science has this article on a new bonebed found near Hilda Alberta.

Scientists have revealed what may be the world’s largest dinosaur graveyard.

The dinosaurs may have been part of a mass die-off resulting from a monster storm, comparable to today’s hurricanes, which struck what was then a coastal area.

The findings could help solve a mystery concerning why the badlands of western Canada are so rich in dinosaur fossils.

The roughly 76-million-year-old fossil beds apparently hold thousands of bones over an area of at least 568 acres (2.3 square km), skeletons that belonged to a roughly cow-sized, plant-eating horned dinosaur known as Centrosaurus. This treasure trove provides the first solid evidence that some horned dinosaur herds were much larger than previously thought, with numbers easily in the high hundreds to low thousands, said senior research scientist David Eberth, a paleontologist and geologist at the Royal Tyrrell Museum in Alberta.

The “mega-bonebed,” which consists of 14 smaller bonebeds, lies in northern Alberta near Hilda, Canada, right by the border with Saskatchewan. The graveyard was actually discovered in 1997, but confirmation of the discovery’s size was detailed this month in the book “New Perspectives On Horned Dinosaurs” (Indiana University Press, 2010).
