Where: Chile (44.6° S, 74.6° W: paleocoordinates 45.6° S, 68.5° 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 more recent published age estimates. STRATIGRAPHIC POSITION: From unknown position within Navidad Fm.
• bed-level stratigraphic resolution
Environment/lithology: coastal; unlithified siliciclastic sediments
Size class: macrofossils
