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.

Evidences from palaeontological and molecular studies suggest that the formation of the SE Asian ancestral centre of diversity occurred during the Miocene. Under the umbrella of the Throughflow project, delta-front patch reefs from 42 outcrops were studied in East Kalimantan (Indonesia), including extensive collections of tens of thousands of specimens within 265 samples. This research aims to answer how diverse were corals during the Miocene and which environmental factors played a role in their diversification on both, temporal and spatial scales. Coral morphologies seem to respond to the gradient of siliciclastic input created by the Mahakan Delta system. Platy-coral assemblages were common in the vicinity of the delta, characterized by a higher turbid-water regime, and mainly from the Early to Middle Miocene (up to Serravallian age). On the other hand, communities of branching corals mixed with scattered massive coral heads were more frequent during the Late Miocene (Tortonian to Messinian age) in settings located towards the north, far-off the delta influence. Although preliminary (\<10\% of samples examined), species diversity was high in both platy and branching coral assemblages, and comparable to modern coral settings living under similar environmental conditions. A total of 51 morphospecies (36 genera) have been identified so far, from which only three genera are considered as extinct, Dictyaraea, Anisocoenia, and Fungophyllia. Whether the observed species turnover is due to major global environmental changes after the Middle Miocene, or it is merely explained by switching of the Mahakan Delta gradient, or a combination of both, is an aspect to be examined in further integrated analysis including geochemistry and sedimentology.

Southeast Asia hosts the maximum centre of coral diversity. Evidence from palaeontological and molecular studies suggests that the Miocene was an important period for diversification in the region. However, the fossil record is markedly undersampled. Of the \~{}200 species of azooxanthellate corals present in the region, only 49 species are known in the fossil record. As part of the Throughflow ITN project, we are collecting new data to document the Miocene diversity of zooxanthellate and azooxanthellate scleractinians from shallow and deep-water habitats preserved in outcrops of East Kalimantan (5-20 Million years old). This project has completed two five-week long field seasons and is currently processing samples. So far, we have identified the azooxanthellate taxa Caryophyllia, Stephanocyathus, Flabellum, Heterocyathus, and Madrepora. Preservation can be excellent allowing geochemical analysis to understand the paleoenviromental conditions in which these species were living. In combination with parallel studies on shallow water ecosystems, these new data provide insights to the origins of the high diversity in this region.

Their role as rapid colonizers of new substrates has been suggested, but little is still known to support this idea. To address this question, larger benthic foraminifera assemblages have been studied in the paleoenvironmental reconstruction of a Langhian (Middle Miocene) shallow-water patch reef, as part of a broader multitaxon fossil comunity analysis, including corals, coralline algae, and bryozoans. The studied outcrop (approx. 80 m wide and 25 m thick) is located at the northeast margin of the Kutai Basin near Bontang (Indonesia). The patch-reef was developed in mixed carbonate-siliciclastic depositional environment and despite the high terrigenous input affecting water transparency, this reef contains a diverse marine biota. Five different facies types were distinguished based on lithology and fossil content: foraminifera packstone, bioclastic packstone with foralgal communities, thin-platy coral sheetstone, platy-tabular coral platestone, and shales. Excluding the fossil barren shales facies, only larger benthic foraminifera occur in all four remaining facies types, showing the ability to rapidly adapt to changes in environment. In the current study, high siliciclastic input caused fluctuations in light levels, but also resulted in deposition of soft-bottom substrate. In newly developed conditions, the larger benthic foraminifera appear first and mark the initiation of reef growth. The persistence of LBF throughout the fossil reef succession indicates their high tolerance to terrigenous input and also highlight the role of foraminifera as primary colonizers, proving themselves as important faunal pioneers, particularly in mixed carbonate-siliciclastic systems.}, author = {Vibor Novak and Nadiezhda Santodomingo and Willem Renema} } @conference {2003, title = {Burdigalian turbid water patch reef environment revealed by larger benthic foraminifera}, booktitle = {The EGU General Assembly 2012}, year = {2012}, month = {22/04/2012}, address = {Vienna}, abstract = {Ancient isolated patch reefs outcropping from siliciclastic sediments are a trademark for the Miocene carbonate deposits occurring in East Kalimantan, Indonesia. They develop in transitional shelf sediments deposited between deltaic and deep marine deposits (Allen and Chambers, 1998). The Batu Putih Limestone (Wilson, 2005) and similar outcrops in adjacent areas have been characterized as shallow water carbonates influenced by high siliciclastic input, showing low relief patch reefs in turbid waters. Larger benthic foraminifera (LBF) are excellent markers for biochronology and paleoenvironmental reconstruction. This study aims to reveal age and paleoenvironment of a shallow water carbonate patch reef developed in mixed depositional system by using LBF and microfacies analysis. The studied section is located near Bontang, East Kalimantan, and is approximately 80 m long and 12 m high. It is placed within Miocene sediments in the central part of the Kutai Basin. Patch reef and capping sediments were logged through eight transects along section and divided into nine different lithological units from which samples were collected. Thin sections and isolated specimens of larger benthic foraminifera were analyzed and recognized to species level (where possible) providing age and environmental information. Microfacies analysis of thin sections included carbonate classification (textural scheme of Dunham, 1962) and assemblage composition of LBF, algae and corals relative abundance. Three environmentally indicative groups of LBF were separated based on test morphology, habitat or living relatives (Hallock and Glenn, 1986). Analysed foraminifera assemblage suggests Burdigalian age (Tf1). With use of microfacies analysis nine successive lithological units were grouped into five facies types. Paleoenvironmental reconstruction of LBF fossil assemblage indicate two cycles of possible deepening recorded in the section. Based on high muddy matrix ratio in analyzed thin-sections we still cannot conclude whether they were deeper water assemblage, or that they occurred in shallower water and influenced by turbid conditions as the result of terrigenous input. According to preliminary analysis and siliciclastic content in the sediments the later one should be more likely. Further work will include additional fossil groups analysis (corals, algae and bryozoans), detailed petrographical analysis and Strontium isotope stratigraphy.}, author = {Vibor Novak and Willem Renema and the Throughflow Project} } @article {2001, title = {Pyrisinellidae, a new family of anascan cheilostome bryozoans}, journal = {Zootaxa}, volume = {3534}, year = {2012}, month = {11/2012}, pages = {1-20}, keywords = {BRYOZOA, Cheilostomata, fossil, new taxa, RECENT}, issn = {1175-5326}, url = {http://www.mapress.com/zootaxa/list/2012/3534.html }, author = {Emanuela Di Martino and Paul D Taylor} } @article {2000, title = {Systematics and life history of Antoniettella exigua, a new genus and species of cribrimorph bryozoan from the Miocene of East Kalimantan (Indonesia)}, journal = {Bollettino della Societ{\`a} Paleontologica Italiana}, volume = {51}, year = {2012}, month = {09/2012}, pages = {99-108}, keywords = {Antoniettella exigua gen. et sp. nov, BRYOZOA, East Kalimantan, life history, Miocene}, issn = {0375-7633}, author = {Emanuela Di Martino and Paul D Taylor} } @conference {1993, title = {Towards a synthesis of Cenozoic pantropical paleontology}, booktitle = {12 ICRS}, year = {2012}, month = {8-13 July 2012}, address = {Cairns, Australia}, url = {http://www.icrs2012.com/Downloads/ICRS2012_Book_of_Abstracts.pdf}, author = {Kenneth G.

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.
