Loc. 3 - Altos de Rapel [Navidad Formation] (Miocene of Chile)

Where: Chile (34.0° S, 71.8° W: paleocoordinates 34.8° S, 66.3° 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

• ENVIRONMENT: Shallow marine, on the basis of faunal composition.
• SPECIFIC LITHOLOGY: Not stated in text, but presumably siliciclastic. LITHIFICATION: Unlithified, based on figured specimens.

Size class: macrofossils
