• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kaskapau Formation, Early/Lower Turonian (93.5 - 89.3 Ma)

• At Watino, Cretaceous sandstone is exposed at river level and the bone bed material is known only from loose blocks in heavily slumped debris. The nearest well-exposed section is at Hunting Creek, located 8 km NNE of Watino, where the upper part of the Dunvegan Formation and lower part of the overlying Kaskapau Formation are exposed. Using sea-level as a datum, the top of the Dunvegan Formation can be traced southward from Erin Lodge on the Peace River, to Hunting Creek near the Smoky River, and then projected south to Watino where the Dunvegan-Kaskapau contact is predicted to lie about 70 m above the level of the Smoky River. Therefore, rocks exposed near water level in the vicinity of Watino are probably part of the Dunvegan Formation, while those above, including the sediments with the fossil material, are part of the Kaskapau Formation.
