In Bee, Karnes, and DeWitt Counties, formation is identical with the section assigned to the Lower Lagarto by Weeks (1933, AAPG Bull., v. 17, no. 5) and is part of section assigned to Lagarto (emended) by Plummer and others (Univ. Texas Bull. 3232, 1933). Recognized in southern Texas. Age is late Miocene.
