High diversity is concentrated in and around reefs. A large variety of organisms, including corals and fish, but also molluscs, crustaceans and echinoderms contribute to this high diversity. In order to understand the timing and the context of the origin of the modern biodiversity hotspot, the fossil record needs to be documented. However, reef facies often suffer strong diagenesis, compromising the fossil record of reef and reef-associated organisms. Here we present an assessment of a well-preserved Late Miocene mollusc fauna from Bontang (East Kalimantan, Indonesia). The fauna is found in association with branching corals, dominated by Dictyaraea. The mollusc fauna is dominated by predatory and browsing carnivorous snails and includes reefal indicators such as the gastropod Coralliophyla and the bivalve Tridacna. The new Bontang fauna gives a glimpse of the diversity and ecological composition of a Late Miocene mollusc fauna from a so-called coral-carpet environment.</p>

Understanding the development of this biodiversity hotspot through the Cenozoic could answer numerous questions about the responses of highly diverse faunal associations to small and large scale environmental changes. When assessing marine biodiversity through time comparisons of taxon diversity are only meaningful when comparing faunas from similar habitats. To evaluate diversity through time within the same ecological setting, it is indispensable to reliably discriminate different habitats. A good example for the difficulties which may occur when identifying marine paleo-habitats is the challenge of recognizing seagrass vegetation in the fossil record. Due to the low preservation potential of marine angiosperms, indirect indicators, e.g. associated organisms with a higher potential for preservation, are commonly used to infer the presence of seagrass meadows in the geological past. Because of their high fossilization potential and their abundance in marine habitats mollusks yield the possibility to be useful paleo seagrass indicators. Here we assess the potential use of indicator species, species and feeding guild composition of whole assemblages, as well as stable isotope signals in shells for their suitability to determine seagrass vegetation in the Miocene of Indonesia.</p>
