• coordinate stated in text

• outcrop-level geographic resolution

When: Pawkowki Formation, Early/Lower Campanian (83.5 - 70.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Pawkowki Formation, which overlies the Early Campanian Milk River Formation, is equivalent to the Lea Park Fm, and is overlain by the Judith River Fm (Late Campanian).
