The Waynesburg Formation is a coal, sandstone, and siltstone geologic formation in West Virginia and Pennsylvania. It preserves fossils dating back to the Permian period.
The Waynesburg Formation has a complicated history with the name being assigned to up to six different stratigraphic units.[2] It consists of a basal coal bed, an unnamed sandstone member formerly called the Waynesburg Sandstone, and a sandy siltstone member.[3] The basal coal member is considered mineable.
