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 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 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 ...
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 Burgess Shale, a series of fossil beds in the Canadian Rockies, was first noticed in 1886 by Richard McConnell of the Geological Survey of Canada (GSC).His and subsequent finds, all from the Mount Stephen area, came to the attention of palaeontologist Charles Doolittle Walcott, who in 1907 found time to reconnoitre the area.

Discovery of soft body preservation at the Walcott–Rust quarry pre-dates Walcott's discovery of the more famous Burgess Shale lagerstätte by 40 years. [ 5 ] Walcott left the area and active working of the quarry in 1876 (his wife Lura Ann died of tuberculosis on January 23, 1876) although he returned for brief periods throughout his career.
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 ...
