Where: Alberta, Canada (49.3° N, 112.8° W: paleocoordinates 57.0° N, 78.5° W)

• coordinate stated in text

• local area-level geographic resolution

When: Baculites compressus ammonoid zone, Blood River Sandstone Member (Foremost Formation), Late/Upper Campanian (83.5 - 70.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Blood River Sandstone, which overlies gradationally the Late Campanian Bearpaw Shale, and is presumably overlain by the Eastman Fm (Early Maastrichtian).

Late Campanian according to Dawson et el. - Geological Atlas of the Western Canada Sedimentary Basin. STRATIGRAPHIC POSITION: From unknown position within the Foremost Fm.
