This assemblage has much in common with that of the Brandywine Formation of Maryland and the Eastover Formation of Virginia which are of late Miocene or early Pliocene age. The environment of deposition of the Bethany was probably deltaic, and that of the lower Beaverdam fluviatile.en-USBethany formationBeaverdam FormationMiocenePliocenedeltaicfluviatileTechnical Report
