The Bull Fork Formation is a geologic formation in north central Kentucky and southwestern Ohio. It preserves fossils dating back to the Ordovician period.[1]

John H. Peck assigned strata previously called the Arnheim, Waynesville, Liberty, and Whitewater Formations in Kentucky to the Bull Fork Formation.[2][3]
