Burgess Shale is a fossil formation that consists of complete traces of soft-bodied animals of the Middle Cambrian Epoch and it is collected from a fossil bed in the Burgess Pass of the Canadian Rockies. It is one of the best-preserved and most significant fossil formations in the world. It was discovered in 1909 and more than 60,000 specimens have been collected from the region.
