Where: San Saba County, Texas (31.3° N, 99.0° W: paleocoordinates 9.2° S, 36.6° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Strawn Group, Moscovian (315.2 - 307.0 Ma)
• The locality is the same, or very close to, the Big Uncle Creek Stop in the field trip guidebook of Grayson and Merrill (1991), which is described as being 2.80 km west and slightly north-west of the centre of Richland Springs. This field trip stop is in the upper Strawn Group. The age, as indicated by conodonts Idiognathodus delicatus, Neognathodus medadultimus, Neognathodus medexultimus and Gondolella bella, is early to middle Desmoinesian (Grayson et al. 1985; Barrick et al. 2004).
• group of beds-level stratigraphic resolution
Environment/lithology: marine; lithified sandstone
Size class: macrofossils
Reposited in the TMM
• These specimens were found long ago, probably as long ago as the 1893 surveys of E. Cope and W.F. Cummins.
