Where: Bolivia (17.4° S, 66.2° W: paleocoordinates 60.2° S, 107.4° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Catavi Formation, Lochkovian (419.2 - 410.8 Ma)

• Unit C2 of Rehfeld and Mehl (1988, PBDB ref. 7146). There has been some uncertainty about age of this unit. Judgment of authors supported by trilobites and by presence of tabulate Pleurodictyum and typically Lochkovian chitinozoans.

• member-level stratigraphic resolution

Environment/lithology: marine; concretionary, ferruginous, micaceous, argillaceous sandstone
