Capilla de la Santa Cruz de Palmarito, Locality 7 (Permian of Venezuela)

Where: Merida, Venezuela (8.0° N, 71.3° W: paleocoordinates 5.5° S, 34.4° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Palmarito Formation, Kungurian (279.3 - 272.3 Ma)

• Paving stone, could not be traced to outcrop; 1 m square and 25 cm thick. Palmarito Fm contains Perrinites hilli and Parafusulina of Kungurian age.

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, shelly/skeletal, gray, silty packstone

• Shallow warm water, close to a shoreline of moderate relief (abundance of angular quartz fragments). Most breakage resulted from post-depositional compaction. Low abrasion and abundant micrite suggests low energy conditions.
• Dark gray, petroliferous, fossiliferous, very silty limestone. Heavily infiltrated by hydrocarbons. Sand and silt fractions display primitive sorting, with mm-scale graded beds. Compositionally a biomicrite containing sponge spicules and angular quartz and rock fragments. Soft-sediment deformation with recrystallization and intergranular welding. Texturally a packstone.

Size class: macrofossils

Preservation: original calcite

Collection methods: bulk, mechanical,

• 1 m square and 25 cm thick. Fossils identified from cut slabs.
