Also known as MVA(F)85-182

Where: British Columbia, Canada (49.6° N, 122.0° W: paleocoordinates 49.3° N, 74.4° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Brokenback Hill Formation, Albian (113.0 - 100.5 Ma)

• Tuffaceous sandstone of Brokenback Hill Formation. The Brokenback Hill Fm ranges from upper Valanginian to middle Albian in age. All colllections have relatively fine temporal resolution however due to ammonite biostratigraphy. SPECIFIC AGE DATA: The ammonite identfied as Ammonoceratites sp. closely resembles the specimen figured in McLearn (1972) from the Queen Charlottes Islands where it is associated with Middle Albian fauna. Arkell et al. (1957) suggested a Late Aptian to Cenomanian age for Ammonoceratites.

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, tuffaceous sandstone

Size class: macrofossils

Preservation: cast, mold/impression
