Where: British Columbia, Canada (55.2° N, 121.5° W: paleocoordinates 56.8° N, 69.8° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Boulder Creek Formation, Middle Albian (109.0 - 105.3 Ma)

• STRATIGRAPHIC RELATIONS: From the Boulder Creek Fm (formely Boulder Creek Mbr of the Comotion Fm), which gradationally overlies marine shales and siltstones of the Hulcross Formation and conformably underlies marine shales of the Hasler Formation. Equivalent beds are found in the Cadotte Member and, possibly in the Paddy Member of the Peace River Formation of the Peace River Plains. In the foothills near Grande Cache equivalent beds may be present in the uppermost beds of the Luscar Group. The formation correlates with beds in the middle Buckinghorse Formation in the Muskwa River area, and the Tussock Member of the Scatter Formation of the Liard River area.. AGE: Early to Middle Albian, on the basis of ammonite biostratigraphy. STRATIGRAPHIC POSITION: List based on the entire formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; lithified siliciclastic sediments

Size class: macrofossils

Preservation: cast, mold/impression

Reposited in the GSC
