Also known as Kahn Quarry, Driver Ranch
Where: Knox County, Texas (33.7° N, 99.9° W: paleocoordinates 2.6° N, 29.2° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Flowerpot Shale Member (San Angelo Formation), Kungurian to Kungurian (279.3 - 268.8 Ma)
• The upper San Angelo Fm. of Olson (1962) is widely identical to the lower part of the Flowerpot Shale Member of the upper San Angelo Fm. (sensu Smith, 1974, University of Texas Bureau of Economic Geology, Report of Investigations No. 80). The San Angelo Fm. (Texas) is a lithostratigraphic equivalent of the Duncan Sandstone, which is below the Chickasha Fm. of Oklahoma. See: Laurin, M. and R. Hook. 2022.
