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 ...
The Walcott Quarry is the most famous quarry of the Middle Cambrian Burgess Shale, located in the Canadian Rockies of British Columbia, bearing the Phyllopod beds.This lies at the base of the Walcott Quarry member, on a ridge between Wapta Mountain and Mount Field, and three other quarries – the Raymond, UE and EZ – lie above it.

The Stephen Formation is a geologic formation exposed in the Canadian Rockies of British Columbia and Alberta, on the western edge of the Western Canada Sedimentary Basin.It consists of shale, thin-bedded limestone, and siltstone that was deposited during Middle Cambrian time (513 to 497 million years ago).

In 1909, geologist Charles D. Walcott discovered the Burgess Shale deposit of fossils with fine details on Mount Burgess. The Burgess Shale is a black shale fossil bed (Lagerstätte) named after nearby Burgess Pass, in which are found new and unique species, many in fact constituting entire new phyla of life, and even today some of these unique ...
The area is known for its natural environment and biological diversity. It includes the Burgess Shale site, a World Heritage Site in its own right from 1980 to 1984, when it was included in the Canadian Rocky Mountain Parks WHS designation. [1] [2]
Outcrop of the Burgess Shale in Yoho National Park, Canada. This is a list of the biota of the Burgess Shale, a Cambrian lagerstätte located in Yoho National Park in Canada. Restoration of the nektonic environment of the site, showing a pair of Anomalocaris canadensis hunting a school of Isoxys acutangulus.
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.
