Where: Cajamarca, Peru (6.6° S, 78.7° W: paleocoordinates 12.1° S, 50.7° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Chulec Formation, Albian (113.0 - 100.5 Ma)

• Collection from a 10 m thick limestone unit, lying below the Pariatambo Formation (late middle Albian) and above the Inca Formation (lower Albian). The Chulec Formation varies in thickness significantly through the regions, ranging from 25 to 500 m in thickness. The formation does appear to have a diachronous base, and in places ranges from Aptian to early Albian at its base, but in most places the formation is considered to fall completely within the middle Albian.

• bed-level stratigraphic resolution

Environment/lithology: lithified, shelly/skeletal, gray, white, yellow limestone

Size class: macrofossils

Reposited in the AMNH

Collection methods: quarrying,

• Collections reposited at AMNH.
