Seventy-two million years ago in Alberta, Canada thousands of dinosaurs were killed by one devastating event.
The mass grave is hidden beneath the slopes of a lush forest and appropriately nicknamed the "River of Death".
A group of paleontologists have embarked on a mission to try solve the mystery of what happened at Pipestone Creek.
Paleontologist Professor Emily Bamforth is Curator at the Philip J. Currie Dinosaur Museum in Alberta and is leading the dig. She joins Kathryn Ryan.
