Locality KAB (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)

• Olson's Upper San Angelo Fm. and basal Flower Pot Fm. belong 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)

• member-level stratigraphic resolution

Environment/lithology: fluvial; brown, green sandstone and sandy shale

• "The upper part of the San Angelo [here] is composed largely of brown and green

•sandstone, and sandy shale channel deposits are poorly developed. Transition to the Flower Pot is rather abrupt, with only a thin, green sandy shale member above the contact"

Size class: macrofossils
