Also known as Chickasha Tongue; Flowerpot Shale; Flowerpot Formation

Where: Blaine County, Oklahoma (36.0° N, 98.4° W)

• Paleocoordinates: 8.0° N, 25.0° W (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Chickasha Formation (El Reno Group), Roadian to Roadian (274.4 - 264.3 Ma)

• "All the deposits are in that part of the Chickasha Formation delineated by Fay (1962) as the Chickasha Tongue within the Flowerpot Formation. The tongue contains four mapped beds, numbered consecutively from 1 (lowest) to 4 (highest)" "The beds are mainly between beds 2 and 3 of the Chickasha Tongue." A measured section consisiting of five typical beds is given for BC-7.

•Minimum age originally entered as >> Capitanian <<. These beds, however, are likely to be older (see, e.g., Reisz & Laurin, 2002, 114(9)).

• group of beds-level stratigraphic resolution

Environment/lithology: deltaic; concretionary, shelly/skeletal, green, conglomeratic, carbonaceous sandstone and red shale

Size class: macrofossils

Preservation: concretion

Collected in 1963, 1972; reposited in the FMNH, UCMP

• Fayella chickashaensis, n. sp. is from hard, green sandstone of bed 2 of measured section at BC-7.

•Rothia robusta, n. sp. from approx. bed 2 of the Chickasha Tongue.

•Five sites in BC-7 have yielded badly weathered specimens of ?Tappenosauridae indet. (bone bearing lithologies include, red shale, low green sandstone section, and siltstone).

•The holotype of Watongia meieri was collected in 1972. It "was found somewhat scattered in red, sandy shale" (Olson, 1974). Nothing is said about the exact horizon, but since Olson (1974) states that "about the same level in this site have been found specimens of Rothianiscus and Cotylorhynchus" it appears that the beds are identical to those from which the older collections were made.
