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: Inca Formation, Albian (113.0 - 100.5 Ma)
• Collection from a 1 m thick limestone unit, lying below the Chulec Formation (early middle Albian) and not far above the Goyllarisquisga Formation, seperated by a disconformiy. The Inca Formation is 80 m thick at this section. The formation was believed to be Aptian by Steinmann (1930), although the present writer believes the unit to be early Albian on the basis of faunal affinities (Parahoplites biozone) and bounding chronostratigraphic relationships.
• bed-level stratigraphic resolution
Environment/lithology: coastal; lithified, shelly/skeletal, sandy limestone
Size class: macrofossils
Reposited in the AMNH
Collection methods: quarrying,
• Collections reposited at AMNH.
