Yaurichambi (d'Orbigny coll) (Permian of Bolivia)

Where: Bolivia (16.3° S, 68.5° W: paleocoordinates 32.9° S, 48.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Copacabana Formation, Asselian (298.9 - 295.5 Ma)

• Yaurichambi is entirely or nearly entirely Asselian (above the sequence boundary and basal units). Specimens came from the top part of the hill, collected from weathered material in the soil.

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified limestone

Size class: macrofossils

Collected by A. d'Orbigny in 1830; reposited in the MNHN

Collection methods: surface (float),

• Many of d'Orbigny's specimens are at MNHN (Paris) but others have apparently been lost. D'Orbigny was in La Paz during June 1830. He only collected a short time ("a few hours") at Yaurichambi because he was ill with a fever.
