Step-by-step explanation:
The Burgess Shale in Yoho National Park in British Columbia, Canada, is a world-famous fossil locality that is famous for its 508 Ma fossils marking the Cambrian explosion. It is one of the earliest fossil beds containing soft-bodied imprints of various life forms, including ancestors of higher life forms like chordates. The Burgess Shale was first discovered in 1909 by Charles Walcott, who collected over 65,000 specimens. Nearby quarries are still yielding new specimens, and there are over seventy similar localities for soft-bodied Cambrian fossils.
