Where: Alberta, Canada (52.8° N, 116.9° W: paleocoordinates 61.0° N, 79.9° W)
• coordinate based on nearby landmark
• basin-level geographic resolution
When: Wapiabi Formation (Alberta Group), Campanian (83.6 - 72.1 Ma)
• STRATIGRAPHIC RELATIONS: From the Waipiabi Fm of the Alberta Gp. Overlies the Cardium Formation conformably or with only slight disconformity.
