Also known as Fossil Hill

Where: Nevada (40.3° N, 118.1° W: paleocoordinates 9.7° N, 44.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: subasperum ammonoid zone, Fassanian (242.0 - 235.0 Ma)

• Smith's collections were made from float; specimens are divided here based on ages from later bedrock-controlled sampling (Silberling & Nichols, 1982; Monnet & Bucher, 2005).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, silty limestone

Size class: macrofossils
