Where: Bolivia (15.5° S, 68.7° W: paleocoordinates 49.9° S, 116.8° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Ananea Formation, Silurian (443.8 - 419.2 Ma)

• "On the basis of this somewhat inconclusive fauna we conclude that the Ananea Formation is largely Silurian, although it may include some Devonian."

• formation-level stratigraphic resolution

Environment/lithology: marine; shale
