Where: Menard County, Texas (30.9° N, 99.5° W: paleocoordinates 19.4° S, 90.6° W)
• outcrop-level geographic resolution
When: Rossodus manitouensis conodont zone, Tanyard Formation (Ellenburger Group), Gasconadian (485.4 - 477.7 Ma)
• Originally given as lower Ellenburger formation, but this is now known as the Tanyard. This is now Skullrockian, but as this overlaps with the latest Cambrian, I'm keeping Gasconade.
•Tribes Hill equivalent?
• formation-level stratigraphic resolution
Environment/lithology: white limestone
Size class: macrofossils
