Paco Chico, ~40 km west of Potosí (Ordovician of Bolivia)

Where: Tomás Frías, Bolivia (19.5° S, 65.9° W: paleocoordinates 43.7° S, 128.8° W)

• coordinate estimated from map

• local area-level geographic resolution

When: San Benito Formation, Caradoc (458.4 - 449.5 Ma)

• Formerly called Zapla or Zapla Tillites; PJW: Re-identified as Cancaniri initially, but although that is contemporaneous with the Zapla, it's too young. This probably is San Benito.

• formation-level stratigraphic resolution

Environment/lithology: foreshore; lithified, pebbly, argillaceous sandstone

• sandstone and shaley-sandy diamictite

Size class: macrofossils

Preservation: cast

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