BC-10 (Chickasha Formation) (Permian to of the United States)

Also known as Chickasha Tongue; Flowerpot Shale; Flowerpot Formation

Where: Blaine County, Oklahoma (36.0° N, 98.2° W: paleocoordinates 4.5° N, 26.8° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Chickasha Formation (El Reno Group), Roadian to Roadian (272.3 - 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 exposures lie between beds 2 and 3 of the Chickasha Tongue.)

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

• bed-level stratigraphic resolution

Environment/lithology: "channel"; green, red shale and sandy shale

• "The vertebrate fauna in the Chickasha deposits lived on a delta marginal to the sea in which the deposits of the El Reno Group were formed."
• "evenly bedded, red and green shales and sandy shales and a remarkably well-exposed channel deposit. It is the latter that has yielded some bone fragments."

Size class: macrofossils

Reposited in the FMNH

• occurrence data for BC-10 restricted to "bone fragments"
