Where: New Mexico (32.6° N, 105.8° W: paleocoordinates 2.5° S, 38.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Holder Formation, Gzhelian (303.7 - 298.9 Ma)

• 30-40 feet below top of Magdalena Formation. Listed as Lower Pennsylvanian but the Magdalena Fm/Gp underlies the Permian so this collection is now probably from the Holder Formation ("Virgilian").

• bed-level stratigraphic resolution

Environment/lithology: lithified limestone

Size classes: macrofossils, mesofossils

Preservation: replaced with silica

Collected by G.A. Cooper; reposited in the USNM

Collection methods: bulk, chemical
