Where: Peru (14.3° S, 75.9° W: paleocoordinates 14.8° S, 73.8° W)
• coordinate stated in text
• hand sample-level geographic resolution
When: Pisco Formation, Tortonian (11.6 - 7.2 Ma)
• The ziphiid skeleton with associated fish remains examined here originates in the lower allomember
•These fossiliferous deposits were first tentatively dated from the late Middle to early Late Miocene (Serravallian to early Tortonian, ca 13–11 Ma [9,18]). The recent record of Lithodesmium reynoldsii, a diatom species with a range between 9.9 and 8.9 Ma , points to a Late Miocene (Tortonian) age .
Environment/lithology: marine; lithified dolomite and poorly lithified diatomite
•its basal portion. This stratigraphic section, including near- shore conglomerates, fine-grained sandstones, diatomites and diatomaceous mudstones, a few dolomitic horizons, and volcanic ash layers, can be subdivided into two overall fining-upwards packages (allomembers) separated by an intraformational angu- lar unconformity  (figure 1).
