GUMO GEO 00006, Upper Scaphopod Bed, Patterson Hills (Permian of the United States)

Where: Culberson County, Texas (31.8° N, 104.9° W: paleocoordinates 4.0° N, 33.4° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Reef Trail Member (Bell Canyon Formation), Capitanian (265.1 - 259.9 Ma)

• USB (Upper Scaphopod Bed) of the Reef Trail Member (post-Lamar Beds of P. B. King 1948)

• bed-level stratigraphic resolution

Environment/lithology: slope; lithified rudstone and lithified packstone

• The USB probably represents a small localized debris flow that originated at the shelf margin and terminated a short distance into the basin.
• discontinuous lens up to 0.2 m thick of poorly sorted, highly bioclastic rudstone/packstone with a fine-grained carbonate matrix

Size class: macrofossils

Preservation: replaced with silica
