Where: Indonesia (7.0° S, 106.6° E: paleocoordinates 9.1° S, 114.2° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Nyalindung Formation, Middle Miocene (16.0 - 11.6 Ma)
• STRATIGRAPHIC RELATIONS: Formerly referred to as Nyalindung Mbr of Cimandiri Fm (Sukamoto, 1990). Overlying Jampang Fm. THICKNESS: From <1 m thick bed within <3 m section; total composite section thickness is estimated at around 40 m. AGE: Age still debated, but most evidence, including molluscan and foraminiferal biostratigraphy suggest a Middle Miocene age. STRATIGRAPHIC POSITION: From upper part of cycle 7 near base of the Nyalindung Fm.
