Stratigraphy
Geological group: | Clear Fork | Formation: | Vale | Member: | "Bullwagon" |
Stratigraphic resolution: | member | ||||
Stratigraphy comments: "Robert Roth, of the Humble Oil and Refining Company of Wichita Falls, Texas, believes that surface and subsurface data show that the beds in question are part of the 'Bullwagon' member of the Vale formation. This places the section high in the Vale, just below the Choza." Olson (1948 p. 190);
the base and top of the Clear Fork Group (i.e., Arroyo, Vale, and Choza formations) are both within the Kungurian: see Wardlaw 2005 (Permophiles) for the base, and DiMichele et al. 2001 (J Paleont) for the top |
Lithology and environment
Primary lithology: | pebbly,green,red conglomerate | ||
Includes fossils? | Y | ||
Lithology description: "The channel fill is largely clay pebble conglomerate, with pebbles ranging from a few millimeters to about 8 cm. in diameter. Rounding of the pebbles is uniformly high, but sphericity is varied. [...] The coarsest material tend to lie at the center of the channel, whereas the marginal parts are predominantly sand or clay with fine scattered pebbles." Olson (1948, p. 191) | |||
Environment: | coarse channel fill | Tectonic setting: | foreland basin |
Geology comments: "The channels are evidence that a rather large, braided stream passed north or south over the area in a valley of considerable width. The region must have had a moderately high annual rainfall to support the fauna and flora. The total rainfall was perhaps not greatly different from what it is today, and the temperature may have been quite similar, with possibly less seasonal variation. The rains, however appear to have been periodic and torrential [...] " Olson (1948, p. 192) |

Taxonomic list comments:“Although Olson (1956:331) stated that FMNH UR 29 was collected from locality ‘KC’ (also in the upper part of the Clear Fork Formation; Olson, 1958: table 1), this is likely a lapsus calami, judging from his statement that this specimen was preserved in association with Captorhinus, and from his faunal lists for localities KB and KC in Olson (1958:430), which list Captorhinus and ‘Edaphosaurid, n. gen., unnamed’ for the locality KB, whereas neither taxon is listed for KC in the 1958 publication.” (Modesto et al, 2016). |
