Where: Baylor County, Texas (33.8° N, 99.0° W: paleocoordinates 1.4° N, 28.9° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Petrolia/Waggoner Ranch Formation (Wichita Group), Artinskian to Artinskian (290.1 - 272.3 Ma)
• Informations in the literature on the stratigraphic position of that collection are contratictory: Fox & Bowman (1966) and Heaton (1979) say Belle Plains Formation, Clark and Carroll (1973) say Clyde Formation. Because the exact geographic position of the locality is stated nowhere, stratigraphy cannot be clarified by using a geological map.
•Petrolia Fm. is formerly known as Belle Plains Fm. Waggoner Ranch Fm. is formerly known as Clyde Fm. (see Hentz, 1988, The University of Texas at Austin Bureau of Economic Geology, Report of Investigations, 170, pp. 1-55)
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size class: macrofossils
Reposited in the FMNH
