Where: Cajamarca, Peru (7.2° S, 78.5° W: paleocoordinates 12.7° S, 50.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• Collection from a 20 m thick shale unit, lying below the Pariatambo Formation (late middle Albian) and 280 m 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.
