Stanley Glacier
The Stanley Glacier locality in British Columbia is an exposure of the "thin" Stephen formation exhibiting soft-tissue preservation. Fossils were discovered by a hiker who reported the find to Parks Canada; this brought the site to the attention of scientists who were able to study the site and describe the new biota. The discovery of Burgess Shale-type preservation in the thin Stephen was unexpected, given the absence of the Cathedral escarpment in the area. Several new species, including ''Stanleycaris ''Stanleycaris'' is an extinct, monotypic genus of hurdiid radiodont from the middle Cambrian (Miaolingian). The type species is ''Stanleycaris hirpex''. ''Stanleycaris'' was described from the Stephen Formation near the Stanley Glacier and Bu ...'', have already been found in exploratory excavations at the site.

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephen Formation
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). It is famous for the exceptional preservation of soft-bodied fossils: the Burgess Shale biota. The formation overlies the Cathedral escarpment, a submarine cliff; consequently it is divided into two quite separate parts, the 'thin' sequence deposited in the shallower waters atop the escarpment, and the 'thick' sequence deposited in the deeper waters beyond the cliff. Because the 'thick' Stephen Formation represents a distinct lithofacies, some authors suggest it warrants its own name, and dub it the Burgess Shale Formation. The stratigraphy of the Thin Stephen Formation has not been subject to extensive study, so except where explicitly mentioned this article applies mainl ...

Parks Canada
Parks Canada (PC; french: Parcs Canada),Parks Canada is the applied title under the Federal Identity Program; the legal title is Parks Canada Agency (). is the agency of the Government of Canada which manages the country's 48 National Parks, three National Marine Conservation Areas, 172 National Historic Sites, one National Urban Park, and one National Landmark. Parks Canada is mandated to "protect and present nationally significant examples of Canada's natural and cultural heritage, and foster public understanding, appreciation, and enjoyment in ways that ensure their ecological and commemorative integrity for present and future generations". The agency also administers lands and waters set aside as potential national parklands, including 10 National Park Reserves and one National Marine Conservation Area Reserve. More than of lands and waters in national parks and national marine conservation areas has been set aside for such purposes. Parks Canada cooperatively manages a ...

Burgess Shale-type Preservation
The Burgess Shale of British Columbia is famous for its exceptional preservation of mid-Cambrian organisms. Around 69 other sites have been discovered of a similar age, with soft tissues preserved in a similar, though not identical, fashion. Additional sites with a similar form of preservation are known from the Ediacaran and Ordovician periods. These various shales are of great importance in the reconstruction of the ecosystems immediately after the Cambrian explosion. The taphonomic regime results in soft tissue being preserved, which means that organisms without hard parts that could be conventionally fossilised can be seen; also, we gain an insight into the organs of more familiar organisms such as the trilobites. The most famous localities preserving organisms in this fashion are the Canadian Burgess Shale, the Chinese Chengjiang fauna, and the more remote Sirius Passet in north Greenland. However, a number of other localities also exist. Distribution Burgess Shale-type biota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathedral Escarpment
The Cathedral Formation is a stratigraphic unit in the southern Canadian Rockies of Alberta and British Columbia, on the western edge of the Western Canada Sedimentary Basin. It is a thick sequence of carbonate rocks of Middle Cambrian age. It was named for Cathedral Mountain in Yoho National Park by Charles Doolittle Walcott, the discoverer of the Burgess shale fossils. The Cathedral Formation includes fossil stromatolites, oncolites, and other algal remains, as well as a few shale beds with trilobites. The Cathedral escarpment on its westernmost edge is thought to have played a major role in the deposition and preservation of the Burgess shale fossils. Lithology and deposition The Cathedral Formation consists primarily of massive, cliff-forming carbonate rocks. It was originally deposited as limestone, much of which may have been secreted by marine algae. Deposition took place in shallow water on an extensive algal reef or carbonate platform that had developed along the weste ...

Stanleycaris
''Stanleycaris'' is an extinct, monotypic genus of hurdiid radiodont from the middle Cambrian (Miaolingian). The type species is ''Stanleycaris hirpex''. ''Stanleycaris'' was described from the Stephen Formation near the Stanley Glacier and Burgess Shale locality of Canada, as well as Wheeler Formation of United States. The genus was characterized by the rake-like frontal appendages with robust inner spines. ''Stanleycaris'' was originally described only from frontal appendages and oral cone. However, in 2022, 268 specimens of ''Stanleycaris'', many of which were complete, were studied, making ''Stanleycaris'' a well documented radiodont. ''Stanleycaris'' had three eyes, a bizarre configuration previously unknown among other radiodont genera; yet this head anatomy supports early differentiation among arthropod head and trunk segmentation. The original description of the taxon appeared in an online supplement to the article published by Jean-Bernard Caron, Robert R. Gaines, M. ...
