• coordinate based on political unit
• local area-level geographic resolution
When: Bone Valley Member (Peace River Formation), Tortonian (11.6 - 7.2 Ma)
• Bradley fauna from Bone Valley Formation; lower beds

•Missimer 1999: The Peace River Formation was deposited from about 11 to 4.3 Ma. It is separated from the underlying, middle Miocene Arcadia Formation by an unconformity with a hiatus of 2 to 4 m.y. The unconformity separating the shallow marine sequence (late Miocene) from the overlying deltaic sequence (early Pliocene) has a hiatal gap of 2 to 6 m.y. depending on geographic location.
