Beattie Peaks Fm (Cretaceous of Canada)

Where: British Columbia, Canada (56.0° N, 122.1° W: paleocoordinates 55.9° N, 64.3° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Beattie Peaks Formation (Bullhead Group), Valanginian (139.8 - 132.9 Ma)

• STRATIGRAPHIC RELATIONS: From the Beattie Peaks, for which lithostratigraphic relations are not discussed. AGE: Valanginian, on the basis of ammonite biostratigraphy; Polyptychites keyserlingi and Buchia keyserlingi zone. STRATIGRAPHIC POSITION: List is representative of the formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; lithified shale and lithified, argillaceous sandstone

• ENVIRONMENT: Not stated in text, but apparently marine siliciclastic.
• SPECIFIC LITHOLOGY: Interbedded shale and very fine-grained argillaceous sandstone. LITHIFICATION: Lithified, on the basis of specimens figured elsewhere.

Size class: macrofossils

Preservation: mold/impression

Reposited in the GSC

Collection methods: surface (in situ),

• COLLECTOR: Triad Oil Co. REPOSITORY: Presumably the Geological Survey of Canada (GSC).
