Where: Peru (6.7° S, 78.5° W: paleocoordinates 12.4° S, 55.6° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Buchiceras bilobatum ammonoid zone, Celendín Formation, Late/Upper Turonian (93.5 - 89.3 Ma)

• LITHOSTRATIGRAPHY: From the Celendín Fm, which locally overlies the Cajamarca Fm (Turonian). AGE: Coniacian, on the basis of ammonite biostratigraphy; Buchiceras bilobatum zone.
