Locality KZ (Upper San Angelo Fm.) (Permian to of the United States)

Also known as Driver Ranch

Where: Knox County, Texas (33.6° N, 99.9° W: paleocoordinates 2.6° N, 29.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Flowerpot Shale Member (San Angelo Formation), Kungurian to Kungurian (279.3 - 268.8 Ma)

• The upper San Angelo Fm. and basal Flowerpot Fm. of Olson (1962) are widely identical to the Flowerpot Shale Member of the upper San Angelo Fm. (see Smith, 1974, University of Texas Bureau of Economic Geology, Report of Investigations No. 80)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; red shale

• "The exposures show a fair development of terrestrial facies, identified on the basis of the nature of the red shale, the lack of gypsum, and the presence of channel sands. Basin facies, formed in the offshore zone, occur in the southwestern part of KZ" (Olson, 1965 p. 112)
• The Flower Pot overlies the San Angelo on a somewhat irregular surface. Its

•base is marked by the usual green sandy shale, rich in gypsum. The clastic materials could have heen derived from the uppermost beds of the San Angelo and

•in places there is transition rather than sharp contact. Overlying this bed are clean red shales, with their continuity interrupted in the central part of the area channel deposits of green standstone and fine conglomerate. About fifty feet from these channel beds, in the red shale was found a series of green nodules, some of which carried rather poorly preserved remains of two or three skeletons of Kahneria." (Olson, 1965 p. 112)
