village of Bontang, Rainy Section (Miocene to of Indonesia)

Where: Indonesia (0.1° N, 117.4° E: paleocoordinates 0.7° N, 119.8° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Burdigalian to Burdigalian (20.4 - 13.8 Ma)

• Burdigalian-Langhian boundary. Lower-Middle Miocen

Environment/lithology: reef, buildup or bioherm; framestone

• Colonies of Antoniettella exigua encrust the bases of platy or, less often, the branches of ramose scleractinian corals. A total of 125 colonies were obtained from two different types of samples: (1) bulk samples, collected directly from the outcrop from a framestone with thin platy and branching corals in a clay matrix; and (2) float samples collected as hand specimens from a pile of platy corals lying adjacent to the outcrop.

Size classes: macrofossils, mesofossils, microfossils

Collection methods: Specimens were collected in June 2011 during the second field season of the Throughflow Project from a muddy carbonate deposit exposed in a road cut, designated TF153 and known colloquially as the ‘Rainy Section’
