Marble Canyon collection (Cambrian of Canada)

Where: British Columbia, Canada (51.2° N, 116.1° W: paleocoordinates 3.6° S, 79.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Ehmaniella trilobite zone, Stephen Formation, Middle Cambrian (509.0 - 497.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: slope; lithified, calcareous claystone and lithified lime mudstone

• like the Walcott Quarry and most other soft-bodied assemblages of the Burgess Shale, occurs in direct association with the Cathedral Escarpment, a major break in submarine topography. The new assemblage was preserved on the offshore margin of the escarpment.
• 2-m horizon of fine-grained claystones near the top of the Stephen Formation

Size classes: macrofossils, mesofossils

Preservation: soft parts, original calcite, original carbon

Reposited in the ROM

Collection methods: quarrying,
