Where: Chile (33.9° S, 71.9° W: paleocoordinates 34.8° S, 66.4° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Navidad Formation, Early/Lower Miocene (23.0 - 16.0 Ma)
• STRATIGRAPHIC RELATIONS: From the Navidad Fm, for which lithostratigraphic relationships are not discussed (in english) in text. AGE: Early-Middle Miocene in text based on macrofossil biostratigraphy. Here, tentatively assigned to Early Miocene based on basal position with formation. STRATIGRAPHIC POSITION: From lower part of Navidad Fm.
