PBDB Collection

S7 locality, Tulip Bed community, Fossil Gully, Mount Stephen (Cambrian of Canada)

Also known as Tulip Beds

Where: British Columbia, Canada (51.4° N, 116.4° W)

• Paleocoordinates: 37.6° N, 120.2° W (Wright 2013)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Bathyuriscus-Elrathina trilobite zone, Campsite Cliff Shale Member (Burgess Shale Formation), Delamaran (511.2 - 506.5 Ma)

• Pagetia bootes subzone, S7 community

• bed-level stratigraphic resolution

Environment/lithology: deep-water; lithified shale

• Aria and Caron (2024) add "more distal palaeoenvironment from the edge of the Cathedral Escarpment compared to the nearby Walcott Quarry, but otherwise shares similar taphonomic pathways with fossils being buried by rapid mud-flow deposits."

Size class: macrofossils

Preservation: mold/impression

Collected by Royal Ontario Museum in 1983 through present

• Caron and Aria (2024) note most samples were collected in 1983, 1996, 2000, 2008, and 2016
