Stratigraphy
| Geological group: | Wichita | Formation: | Belle Plains | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: "about 500 feet above the Coleman Junction." Details for Faunal Zone 2 of Romer 1928: "Beyond the horizon of Godwin Creek is found a series of beds about 200 feet in thickness, of a transitional character, in which thin and impure limestones are occasionally present."
the base of the Artinskian is just above Coleman Junction Formation (Wardlaw 2005, Permophiles), and the "Belle Plains" = Petrolia Formation is below the Waggoner Ranch Formation, whose base equals the base of the Bead Mountain Formation (Tabor et al. 2002), which is in the middle of the Artinskian (Wardlaw 2005) | |||||
Lithology and environment
| Primary lithology: | red claystone |
| Secondary lithology: | "limestone" |
| Lithology description: red-beds and "6-inch limestone" | |
| Environment: | terrestrial indet. |
| Glacial or sequence phase: | transgressive |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: Not the same as "South side of Tit Mountain butte, TMM 40031" locality (Langston 1986); that collection was obviously made much later than the Tit Mountain collection of Romer (1928), which has less detailed locality data.
Romer (1928) paper is a review of vertebrates from the Texas red-beds with previously unreported (or undetailed) localities. | |
