Stratigraphy
| Geological group: | Wichita | Formation: | Waggoner Ranch | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: "65 feet above the Beaverburk" Limestone. Details for Faunal Zone 3 of Romer 1928: "approximately 230 feet in thickness...The total thickness of the Wichita group, as thus defined is, in this region, approximately 780 feet." Clyde Formation is approx. equivalent to Waggoner Ranch Formation (Hetz and Brown 1987). the Waggoner Ranch Formation is equivalent to the Bead Mountain through Lueders formations (Tabor et al. 2002), which are late Artinskian and early Kungurian according to Wardlaw 2005, Permophiles (JA) | |||||
