Also known as Ponon-Trehue Fm., Ponon-Trehue, Argentina

Where: Argentina (35.2° S, 68.2° W: paleocoordinates 30.8° S, 136.9° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Pygodus anserinus conodont zone, Los Leones Member (Lindero Formation), Costonian to Costonian (458.4 - 457.2 Ma)

• PJW: Originally placed in Ponon-Trehue formation; some people still use that for these rocks, but it makes more sense to use the Lindero Formation. This would be the Los Leones member, which overlies the Peletay member.

• member-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; lithified, shelly/skeletal, gray, argillaceous grainstone and limestone

Size class: macrofossils

Collection methods: JA: marked by Novack-Gottshall without explanation as omitting some genera, some macrofossils, some microfossils, and species names, but apparently complete
