Also known as Chickasha Tongue; Flowerpot Shale; Flowerpot Formation
Where: Kingfisher County, Oklahoma (35.9° N, 98.2° W: paleocoordinates 4.5° N, 26.7° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Chickasha Formation (El Reno Group), Roadian to Roadian (272.3 - 264.3 Ma)
• K-1 specimens in Olson (1965) are referred to as "Chickasha Formation, middle Flowerpot age, Upper Permian." The terms Flowerpot and Chickasha Formations are historically used interchangeably Olson and Barghusen (1962).
•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"; lenticular, ferruginous, pebbly, green, red, conglomeratic sandstone and pebbly, brown, sandy conglomerate
•I. Brown to red sandy shale containing a few bones and some plant remains.
•II. Fine, soft, brown sandstone with scattered clay pebbles. Grading into green sandstone in places and becoming hard in vicinity of bones. Source of better preserved specimens.
•III. Hard brown to red conglomerate. Matrix a mixture of sand and shale, larger constituents include clay pebbles, sandstone pebbles, and small cobbles. Contains scattered fragments of bone and traces of plants.
•IV. Rounded and angular fragments of shale and sandstone in a fine, hard matrix forming a conglomerate and breccia. Red to deep brown in color and in part cemented by silica. Bone fragments, well-preserved ribs, and plant remains present.
•V. Soft green sandstone with few bones but abundant plant remains, some fairly well preserved.
•VI. Green shale with some sand. Plant remains but no bones.
Size class: macrofossils
Collection methods: bulk, surface (in situ),
• "about 100 blocks containing vertebrate fossils were removed" from the quarry (Olson 1965).
•Specimen counts have been updated according to Olson 1965. Original specimen counts (Olson and Barghusen 1962) were as follows: R. multidonta (= R. robusta), 6; C. bransoni, 9; A. romeri, 13.
