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.

As part of the Throughflow ITN, the aims of this study are to determine which coral species occurred during this period and to understand how environmental factors controlled coral diversification on both temporal and spatial scales. Our new collections include tens of thousands of specimens from the rich and well-preserved Miocene fossil record of small patch reefs that developed in turbid habitats that are now preserved in the sediments of the Kutai Basin of East Kalimantan (Indonesia). Preliminary results suggest that species diversity was high and comparable to modern coral settings living under turbid environmental conditions. A total of 150 morphospecies from 70 genera have been identified, including nine genera known as extinct. Our findings have revealed that some lineages that were previously known from the Plio-Pleistocene record were already present during the Miocene time. These discoveries have a profound impact on our understanding of the origins of today’s diversity in the Coral Triangle. Further research will focus on the incorporation of these fossils into phylogenetic analyses in order to estimate divergence times and explore the relationship of evolutionary trends with environmental changes at biogeographic scale.

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.

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.1 aNovak, Vibor1 aSantodomingo, Nadiezhda1 aRenema, Willem uhttps://ipaeg.myspecies.info/content/larger-benthic-foraminifera-%E2%80%93-faunal-pioneers-mixed-carbonate-siliciclastic-systems00503nas a2200133 4500008004100000245004900041210004900090260004700139100002800186700002500214700001900239700002900258856008200287 2012 eng d00aOrigins of coral diversity in Southeast Asia0 aOrigins of coral diversity in Southeast Asia aAmsterdam, The Netherlandsc1-6 April 20121 aSantodomingo, Nadiezhda1 aJohnson, Kenneth, G.1 aRenema, Willem1 aProject, the, Throughflo uhttps://ipaeg.myspecies.info/content/origins-coral-diversity-southeast-asia-000771nas a2200181 4500008004100000245013200041210006900173260003600242100002500278700002100303700001700324700002800341700001800369700002400387700002500411700001900436856013400455 2012 eng d00aPalaeoenvironmental reconstruction of a Miocene patch reef in East Kalimantan (Indonesia): a close-up on the bryozoan component0 aPalaeoenvironmental reconstruction of a Miocene patch reef in Ea aBrno Czech Republicc31/05/20121 aDi Martino, Emanuela1 aTaylor, Paul, D.1 aNovak, Vibor1 aSantodomingo, Nadiezhda1 aRösler, Anja1 aBraga, Juan, Carlos1 aJohnson, Kenneth, G.1 aRenema, Willem uhttps://ipaeg.myspecies.info/content/palaeoenvironmental-reconstruction-miocene-patch-reef-east-kalimantan-indonesia-close-bryozo00682nas a2200181 4500008004100000245008700041210006900128260001500197100001700212700002800229700001800257700002500275700002000300700002000320700002500340700001900365856011600384 2012 eng d00aEnvironmental reconstruction of a Langhian patch reef (East Kalimantan, Indonesia)0 aEnvironmental reconstruction of a Langhian patch reef East Kalim c29/03/20121 aNovak, Vibor1 aSantodomingo, Nadiezhda1 aRösler, Anja1 aDi Martino, Emanuela1 aBraga, Juan, C.1 aTaylor, Paul, D1 aJohnson, Kenneth, G.1 aRenema, Willem uhttps://ipaeg.myspecies.info/content/environmental-reconstruction-langhian-patch-reef-east-kalimantan-indonesia00669nas a2200181 4500008004100000245007200041210006900113260003100182100002500213700002100238700001700259700002800276700001800304700002400322700002500346700001900371856009700390 2012 eng d00aBryozoans from a Langhian patch reef in East Kalimantan (Indonesia)0 aBryozoans from a Langhian patch reef in East Kalimantan Indonesi aCatania, Italyc24/05/20121 aDi Martino, Emanuela1 aTaylor, Paul, D.1 aNovak, Vibor1 aSantodomingo, Nadiezhda1 aRösler, Anja1 aBraga, Juan, Carlos1 aJohnson, Kenneth, G.1 aRenema, Willem uhttps://ipaeg.myspecies.info/content/bryozoans-langhian-patch-reef-east-kalimantan-indonesia00615nas a2200121 4500008004100000245007200041210006900113260013300182100002800315700002500343710002400368856010100392 2011 eng d00aHow diverse were reef corals of South East Asia during the Miocene?0 aHow diverse were reef corals of South East Asia during the Mioce aLiège, BelgiumbM.
