ammonites
Iron Canyon, Battle Mountain (Cambrian to of the United States)

Also known as Reef 2275

Where: Lander County, Nevada (40.6° N, 117.1° W: paleocoordinates 2.0° S, 92.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Scott Canyon Formation, Botomian to Botomian (516.0 - 513.0 Ma)

• olistoliths within debris flow near the top of the Ordovician Valmy Formation just above a radiolarian chert and immediately below the Silurian Harmony Sandstone

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks and lithified grainstone

• "deeper water accumulations of talus debris derived from bioconstructions formed in shallow highly agitated waters along the distal seaward margin of a continental margin"
• fragments of microbial-archaeocyath bioconstructions, associated with grainstones and rudstones with bioclastic debris, more diverse algal/microbial and macrofauna assemblages

Size class: macrofossils

Collection methods: peel or thin section,
