KF-3 (Chickasha Formation) (Permian to of the United States)

Also known as Chickasha Tongue; Flowerpot Shale; Flowerpot Formation

Where: Kingfisher County, Oklahoma (35.9° N, 98.2° W: paleocoordinates 4.4° 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)

• "The level is about the same as that of KF-1, which lies about 2.5 miles to the north." A measured section consisting of 6 beds is provided for this locality. Fossil material most likely from bed 4, based on suggestion in text.

•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: deltaic; green sandstone

• "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."
• No direct lithologic description provided with specific fossils, though if bed 4, then green sandstone with shale lenses interfingering.

Size class: macrofossils

Reposited in the FMNH
