Where: Peru (4.3° S, 81.3° W: paleocoordinates 4.5° S, 82.3° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Mancora Tablazo Formation, Early/Lower Pleistocene (2.6 - 0.8 Ma)
• LITHOSTRATIGRAPHY: From the Mancora Tablazo Fm, which unconformably overlies the Taime Fm, and is unconformably overlain by the Talara Tablazo. AGE: Early Pleistocene, on the basis of macrofossil biostratigraphy. STRATIGRAPHIC RELATIONS: Unclear from what part of the formation the collection is derived, so collection should be considered a composite list for the formation.
• formation-level stratigraphic resolution
Environment/lithology: coastal; siliciclastic sediments
Size class: macrofossils
Collected by DeVries
Collection methods: surface (in situ),
• COLLECTORS: Presumably T.J. DeVries, c. 1980's. RESPOSITORY: Not stated in text.
