The story of how the Burgess Shale came to be, of its creatures, attempts to classify them, and where they fit into the scheme of evolution is one of the greatest stories--and one of the hottest controversies--in science.
High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It hold the remains of an ancient sea where dozens of strange creatures lived--a forgotten corner of evolution preserved in awesome detail.
