The Burgess Shale Formation

The Burgess Shale Formation is located in the Canadian Rockies of British Columbia. It is one of the world's most celebrated fossil fields and is listed as a UNESCO world heritage site. It is famous for the exceptional preservation of the soft parts of its fossils.

At 508 million years (Middle Cambrian) old, it is one of the earliest fossil beds containing soft-part imprints.
Burgess Shale contains the best record we have of Cambrian animal fossils. It reveals creatures originating from the Cambrian explosion, an evolutionary burst of animal origins dating 545 to 525 million years ago.
During this period, life was restricted to the world's oceans. The land was barren, uninhabited, and subject to mudslides which periodically rolled into the seas and buried marine organisms. At Burgess, sediment was deposited in a deep-water basin adjacent to an enormous algal reef with a vertical escarpment several hundred meters high.
