Summary:
Authors state that term Teay is considered archaic and that the preferred term is Teays. Teays Formation consists of the lower Gallia Sand Member and the upper Minford Silt Member. Paleomagnetic and stratigraphic data indicate that Minford is early Pleistocene. Fullerton (1986) also placed the Minford and other members of the Teays Formation in the early Pleistocene.
