Where: Peru (7.6° S, 78.9° W: paleocoordinates 8.0° S, 45.8° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Upper Member (Punta Moreno Formation), Late/Upper Tithonian (150.8 - 145.0 Ma)
• The fauna is ascribed to the Alternans zone of the Andean biochronological standard, which is probably equivalent to the Microcanthum zone of Europe, of early Late Tithonian age.
• bed-level stratigraphic resolution
Environment/lithology: delta front; lithified siliciclastic sediments
Size class: macrofossils
Preservation: mold/impression
Collection methods: focus on ammonites
