Divide between Troy Canyon and South Fork of American Canyon (occidentalis) (Triassic of the United States)
Also known as Fossil Hill
Where: Nevada (40.3° N, 118.1° W: paleocoordinates 11.2° N, 42.3° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: occidentalis ammonoid zone, Illyrian (247.2 - 242.0 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
Collected by J.P. Smith; reposited in the USNM
