Whipsaw Creek (University of Alberta) (Eocene of Canada)

Also known as nine mile creek

Where: British Columbia, Canada (49.4° N, 120.6° W: paleocoordinates 54.1° N, 103.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Vermilion Bluffs Member (Allenby Formation), Ypresian (56.0 - 47.8 Ma)

• Whipsaw Creek, British Columbia: an exposure of the Vermillion Bluffs Shale Unit of the Allenby Formation (Princeton Group) on Highway 3 about 10 km south of the town of Princeton. The Vermillion Bluffs Shale Unit exposure at the Hospital Hill locality is dated Early Eocene (52.08 ± 0.12 Ma by preliminary U–Pb zircon ages by Mortensen and Archibald, work in progress), indicating an Early Eocene age for Whipsaw Creek, although an early Middle Eocene age cannot be ruled out for this exposure, pending further results.
