Where: Blaine County, Oklahoma (36.0° N, 98.4° W: paleocoordinates 4.6° N, 26.8° W)
• coordinate estimated from map
• outcrop-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 [vertebrate-bearing] beds lie mainly between beds 2 and 3 of the Chickasha Tongue" mostly in section 35.
•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: "floodplain"; concretionary, red shale and green sandstone
Size class: macrofossils
