Seagrass ecosystems play an important role in sedimentation processes and nutrient cycling and support local biodiversity by providing food and shelter for numerous associated organisms. These ecosystems have been around since the Late Cretaceous. In order to understand their emergence in geological time and their response to past perturbations we have to be able to recognize seagrass communities in the fossil record. However, seagrass itself hardly fossilizes and therefore we are searching for indirect indicators to recognize ancient seagrass vegetation. In this contribution we review molluscan evidence for palaeo-seagrass settings. Indicator species are rare since the majority of seagrass associated molluscs occurs in other marine habitats as well. Furthermore, those habitats appear to be patchy, both spatial and temporal, resulting in mixed occurrences of seagrass and non-seagrass faunas. Often only the high abundance of certain mollusc groups and the general taxonomic composition of a fauna points to seagrass environments. However, the distribution of gastropod trophic guilds in species richness versus abundance data appears to yield patterns that may be very characteristic for the identification of fossil seagrass associated faunas. We are currently applying Indirect PaleoSeagrass Indicators (IPSI’s) to a number of fossil and modern shelly samples, both from seagrass and non-seagrass environments. We also briefly review potential sedimentary and geochemical IPSI’s as well as fossil groups different than molluscs. Identifying seagrass environments enables us to assess diversity trends in such ecosystems through time and to study their response over time intervals with major environmental and climate change.

To fill this knowledge gap, crucial to understand the evolutionary history of reef building coralline algae, we studied CCA in Miocene reefs in the Kutai Basin, the largest sedimentary basin in Borneo that was dominated by siliciclastic sediments of the Proto-Mahakam delta. Local carbonate buildups comprising low relief patch reefs occur within the deltaic succession in shallow and turbid water, influenced by high siliciclastic input (Wilson, 2002). CCA in the Kutai basin are mostly found in association with coral reefs, encrusting corals or fragments of them. In beds with very high siliciclastic content no coralline algae were observed in the outcrops, but corals were still present. Two main CCA assemblages have been recognized in the studied Middle Miocene reefs: 1) a shallow-water assemblage, with two species of Neogoniolithon, thick crusts of Spongites, various Hydrolithon and also Sporolithon and Lithoporella. 2) In darker waters preferentilaly grew melobesioid assemblages, dominated by rhodoliths mainly consisting of Lithothamnion or by thin crusts of Mesophyllum and Sporolithon. This last one is the only assemblage found in mesophotic reefs. CCA of East Kalimantan show occurrences of some extant species earlier than expected. These new first-occurrence dates are being used to produce a detailed time tree of the main reef building CCA species with the help of a new molecular phylogeny based on five genetic markers.
