Figure 8 in Fossils reveal a high diversity of the staghorn coral genera Acropora and Isopora (Scleractinia: Acroporidae) in the Neogene of Indonesia

Figure 8. Acropora samoensis, NHMUK PI AZ 7103, TF505, Bontang gardens sections, East Kalimantan, Late Miocene (9.4–9.8 Ma). A, aspect of a colony in the field found within grey silt-rich sediments, showing a probably caespitocorymbose growth form. B, AZ 7103a, upper view of a branch fragment. C, three branches showing short tubular radial corallites, anticlockwise: AZ 7103a,b,c. D, AZ 7103b (up) and AZ 7103c (down), boring holes interpreted as being made by Lithophaga sp. E, AZ 7103b, electron micrograph showing the upper view of an axial corallite.
