Bontang, East Kalimantan, TF505 (Miocene of Indonesia)

Where: Indonesia (0.0° N, 117.0° E: paleocoordinates 0.1° N, 117.7° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Tortonian (11.6 - 7.2 Ma)

• 9.4-9.8 Ma (early Tortonian)

Environment/lithology: shallow subtidal; silty, cherty/siliceous siltstone

• shallow environment with calm waters and high influence of siliciclastic sediments probably associated with a protected lagoon or sheltered environment. A. samoensis co-occurred with Seriatopora spp. and robust colonies of branching Porites into a compact grey silt-rich sediment layer. Stratigraphic units interbedding contain typical seagrass fauna rich on well-preserved molluscs and specimens of the aspera species group.
• silt-rich sediment layer

Size class: macrofossils
