Where: British Columbia, Canada (49.2° N, 124.1° W: paleocoordinates 52.9° N, 90.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Haslam Formation, Late/Upper Santonian (85.8 - 83.5 Ma)

• Ammonites from nearby outcrops that seem to be stratigraphically approximate contain tentatively identified specimens of the ammonite Canadoceras yokoyamai, indicative of early early Campanian age. Haggart & Graham (2018) later determined a late Santonian age from the upper quarry itself, on the basis of ammonites, inoceramids, and the crinoid Marsupites.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; lithified siliciclastic sediments

Size class: macrofossils
