Stratigraphy
| Geological group: | Cow Head | Formation: | Shallow Bay | Member: | Downes Point | Local bed: | Boulder #363 |
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Boulder #363 is from the Zacanthoidid-Pagetia Biofacies. While this monograph deals with the Kindle Zone 1, fauna of the Kindle Zones 2-5 can be found in Westrop et. al 1996. The Downes Point Member is about 100m thick and the general paleoenvironment is a shelf edge/upper slope environment which transported fossils as debris flows forming a deep water sediment apron.. | |||||

Collection methods and comments
| Collection methods: | survey of museum collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: Not all boulders were assignable to a biofacies and only trilobites were described, however other taxa are not known to be omitted since there is no mention of them in the text. The trilobites described here are part of the C. H. Kindle Collection at the Geological Survey of Canada. | |
