• 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)
