The Burgess Shale is a fossil-bearing deposit exposed in the Canadian Rockies of British Columbia, Canada. [ 2 ] [ 3 ] It is famous for the exceptional preservation of the soft parts of its fossils. At 508 million years old ( middle Cambrian ), [ 4 ] it is one of the earliest fossil beds containing soft-part imprints.
The earliest Burgess Shale-type biota to be described, being documneted 25 years before the Burgess Shale itself. [47] Kaili Formation. 513–501 Ma Guizhou, China The middle part of the Kaili Formation, the Oryctocephalus indicus Zone, contains a Burgess Shale-type lagerstätte with many well-preserved fossils known collectively as the Kaili ...
The Burgess Shale is a series of sediment deposits spread over a vertical distance of hundreds of metres, extending laterally for at least 50 kilometres (30 mi). [18] The deposits were originally laid down on the floor of a shallow sea; during the Late Cretaceous Laramide orogeny, mountain-building processes squeezed the sediments upwards to their current position at around 2,500 metres (8,000 ...

Harry Blackmore Whittington FRS (24 March 1916 – 20 June 2010) was a British palaeontologist who made a major contribution to the study of fossils of the Burgess Shale and other Cambrian fauna. [1] His works are largely responsible for the concept of Cambrian explosion , whereby modern animal body plans are explained to originate during a ...
A Burgess Shale trilobite showing soft-part preservation. Burgess Shale-type deposits occur either on the continental slope or in a sedimentary basin.They are known in sediments deposited at all water depths during the Precambrian (Riphean stage onwards), with a notable gap in the last 150 million years of the Proterozoic.

The Phyllopod bed, designated by USNM locality number 35k, [1] is the most famous fossil-bearing member of the Burgess Shale fossil Lagerstätte.It was quarried by Charles Walcott from 1911–1917 (and later named Walcott Quarry), and was the source of 95% of the fossils he collected during this time; [2] tens of thousands of soft-bodied fossils [3] representing over 150 genera [4] have been ...
