Figure 5 in Fossils reveal a high diversity of the staghorn coral genera Acropora and Isopora (Scleractinia: Acroporidae) in the Neogene of Indonesia

Figure 5. Diagram of morphometric characters used to describe Acropora and Isopora fossil specimens. A, schematics of arborescent (up) and corymbose (down) colonies showing distance between branches (character 1) and branch angle (character 6). B, single branch. C, calice from top view. D, branch tip from lateral view illustrating corallite and coenosteal measurements. E, upper view of the same branch tip illustrating an example of corallite arrangement sequence with one axial corallite and the first two series of radial corallites (r1, r2): 1–2–6. Numbers correspond to characters 1–17 listed in Table 2. Modified from Wolstenholme et al. (2003).
