Coral patch reefs in the Miocene Mahakam Delta in East Kalimantan (Borneo, Indonesia) grew in shallow marine turbid waters. These patch reefs developed from delta front to deeper (prodelta) settings in areas with temporary reduced siliciclastic input. Langhian reef deposits are well exposed in limestone quarries in the Samarinda area and locally include microbial carbonates. Two different types of microbial carbonates have been found around Samarinda in two localities 2 km apart. These sections were logged in detail and 208 samples were collected. Meso and macrostructure of microbialites were identified at the outcrops. Thin sections from carbonate samples were examined under optical microscope and microfacies were classified using the Dunham (1962) and Insalaco (1998) terms. The carbonate content was analyzed using Total Inorganic Carbon analysis, with 12% carbon as a standard for carbon calibration. In the northern section, microbialites occur as low-relief domes, up to 2 m wide and 0.5 m high, with internal lamination, developed around large coral fragments at the transition from reef deposits to fine-grained siliciclastics.
The second type of microbialites has been found in the southern locality as decimeter-scale nodules ("megaoncoids") formed around nuclei of large coral fragments. Small nodules were bound together into bigger nodules. Microbial micrite with laminated to digitated fabrics intergrew with coralline algae to form the thick covers of these "megaoncoids", which laterally change into coral boundstones. In both sections microbialites are not components of the reef framework. They grew around large coral fragments on the flanks of the patch reefs. The microbialites that form low relief domes developed on nearly flat, stable seafloor seawards of the patch reef. The "megaoncoids" in the southern section formed as a result of downslope movement of coral fragments coated by microbialite/coralline algal crust. The steep slope at the flank of the patch reef favored falling and overturning of encrusted corals and continued growth of microbial crusts on other sides of nodules.

Microbial carbonates are deposits that form by the activity of bentic microbial communities. Microbialites usually form domical, columnar or conical structures and can have laminated, clotted, dendritic or homogenous macrofabric. They have a broad distribution and can grow in a variety of different environments such as hot springs, freshwater lakes, hypersaline lakes, reefs and other marine environments. This research focuses on microbialites associated to coral reefs. Coral patch reefs in the Miocene Mahakam Delta in East Kalimantan (Borneo, Indonesia) grew in shallow marine turbid waters.

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.

Miocene crustose coralline algae (CCA) from the South East Asia are poorly known, although the Miocene is the epoch of the onset of the biodiversity hotspot in the region and CCA are crucial to understand the evolutionary history of reef building. To fill this knowledge gap, CCA from Lower and Middle Miocene reefs and related carbonates in the Kutai Basin in East Kalimantan (Borneo, Indonesia) have been studied. The Kutai Basin was dominated by siliciclastic sediments of the Proto-Mahakam delta and only locally carbonate buildups occur laterally to or within the deltaic succession. CCA in the Kutai Basin occur in low-energy shallow-water platform carbonates and in association with coral reefs, encrusting the corals or bioclasts. Two main CCA assemblages have been recognized: 1) A shallow-water assemblage (S-assemblage), dominated by Neogoniolithon spp., thick crusts of Spongites spp., and Hydrolithon spp.; and 2) the D-assemblage, mainly consisting of thin crusts of Lithothamnion spp., Mesophyllum spp., and Sporolithon spp., which grew in darker waters. Light reduction in reefs in the Proto-Mahakam delta was due to increased water depth or higher turbidity by higher siliciclastic input. Assemblages with intermediate composition (I-assemblages) can also be found. Common CCA with large cells fusions and groups of heterocysts, typical features of modern reef CCA, in the S-assemblages in the Middle Miocene of East Kalimantan reflect the initiation of the reef-building CCA flora in the Indo-Pacific region. The occurrence of this kind of CCA confirms the biogeographic differentiation of a tropical reef flora.

Currently, SE Asia is the global marine centre of diversity. 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.

Today’s centre of maximum marine biodiversity is located in the Indo-Malayan region. 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.

We studied localities outcropping on Mangkalihat Peninsula, Kutai Basin, and Java, that were deposited in a time interval from Early (Te5) to Middle Miocene (Tf2). In order to reconstruct depositional environments and obtain biostratigraphic information, larger benthic foraminifera (LBF) assemblages were analysed from these three locations. The northernmost, and stratigraphically oldest, from the studied carbonates are exposed on Mangkalihat Peninsula. They were formed in shallow-water environment on carbonate platform. Stratigraphically important LBF indicate Early to Middle Miocene age (Te5-Tf1). Towards the south, in the Kutai Basin, isolated patch reefs occur within siliciclastic sediments, developed in mixed carbonate-siliciclastic depositional systems. In general, LBF assemblage is indicative of low-light conditions typical for mesophotic reefs. Based on LBF late Early to Middle Miocene age (Tf1-Tf2) can be suggested. The southernmost carbonate exposures are located on Central Java, in the Bulu Limestone member. The LBF assemblage composition indicate environmental conditions typical for continental shelf edge. Middle Miocene (Tf2) can be inferred for these limestones based on LBF. Here we present an overview of Indonesian Early to Middle Miocene LBF assemblages in a range of depositional environments. We will assess the interplay between stratigraphical and environmental control on LBF assemblages. 1 aNovak, Vibor1 aRenema, Willem uhttps://ipaeg.myspecies.info/content/foraminiferal-assemblages-miocene-carbonates-indonesia00923nas a2200289 4500008004100000245008400041210006900125260003500194300000800229490000700237653001400244653002400258653001200282653003800294653001600332100002800348700001700376700002100393700002500414700002100439700002100460700002400481700001800505700001900523700002500542856006600567 2012 eng d00aDevelopment of a turbid reef in the Middle Miocene (East Kalimantan, Indonesia)0 aDevelopment of a turbid reef in the Middle Miocene East Kalimant aCharlotte, North Carolina, USA a6230 v7710aINDONESIA10amarginal ecosystems10aMiocene10apalaeonvironmental reconstruction10apatch reefs1 aSantodomingo, Nadiezhda1 aNovak, Vibor1 aMarshall, Nathan1 aDi Martino, Emanuela1 aFraser, Nicholas1 aLoGiudice, Elena1 aPretković, Vedrana1 aRösler, Anja1 aRenema, Willem1 aJohnson, Kenneth, G. uhttps://gsa.confex.com/gsa/2012AM/webprogram/Paper209284.html00560nas a2200121 4500008004100000245010500041210006900146260002500215100002500240700001900265710002400284856013000308 2011 eng d00aLate Cenozoic history of the Southeast Asian marine biodiversity maximum: new data for old questions0 aLate Cenozoic history of the Southeast Asian marine biodiversity aPlymouthc19/12/20111 aJohnson, Kenneth, G.1 aRenema, Willem1 aThroughflow Network uhttps://ipaeg.myspecies.info/content/late-cenozoic-history-southeast-asian-marine-biodiversity-maximum-new-data-old-questions00848nas a2200277 4500008004100000245005900041210005800100300001200158490000800170100001900178700002100197700002400218700001800242700001300260700002500273700001300298700001800311700002200329700001900351700001600370700002300386700002600409700002200435700002100457856009200478 2008 eng d00aHopping Hotspots: global shifts in marine biodiversity0 aHopping Hotspots global shifts in marine biodiversity a654-6570 v3211 aRenema, Willem1 aBellwood, D., R.1 aBraga, Juan, Carlos1 aBromfield, K.1 aHall, R.1 aJohnson, Kenneth, G.1 aLunt, P.1 aMeyer, C., P.1 aMcMonagle, L., B.1 aMorley, R., J.1 aO’dea, A.1 aTodd, Jonathan, A.1 aWesselingh, Frank, P.1 aWilson, M., E.
