Crustose coralline algae (CCA) of this epoch from South East Asia, however, are poorly known, despite their importance for the generation and maintenance of reef biodiversity.

We studied CCA in Miocene reefs in the Kutai Basin (East Kalimantan, Indonesia) to fill this knowledge gap, crucial to understand the evolutionary history of reef building algae. CCA are mostly found encrusting corals and forming nodules together with foraminifers. Two main CCA assemblages can be recognized in the studied reefs: 1) A shallow-water assemblage, comprising two species of Neogoniolithon, several Hydrolithon species, Spongites, Lithoporella, and also Sporolithon. 2) A melobesioid assemblage that preferentially grew in darker waters, consisting of Lithothamnion, Mesophyllum and Sporolithon. The recorded palaeodepth distribution of CCA assemblages is consistent with the one reported from modern and fossil coral reefs.

Miocene CCA of East Kalimantan include some extant species, which appeared earlier than previously known. These new first-occurrence dates are used to produce a detailed time tree of the main reef building CCA species with the help of a new molecular phylogeny, which is based on five genetic markers (18S, 28S, COI, psbA, UPA). The sequences have been obtained from samples from Indo-Pacific localities and Genbank. This study comprises the biggest set of reef building CCA taxa ever analysed before, and aims to disentangle the polyphyly of traditional taxa such as the mastophoroid and lithophylloid subfamilies.1 aRösler, Anja1 aBraga, Juan, C.  uhttps://ipaeg.myspecies.info/content/evolution-indo-pacific-reef-building-coralline-algae00565nas a2200133   4500008004100000245009700041210006900138100001900207700002000226700001800246700002200264700001900286856012600305       2013                        eng d00aIndonesian Throughflow variability through the Makassar Strait during the last glacial cycle0 aIndonesian Throughflow variability through the Makassar Strait d1 aSchroeder, Jan1 aKuhnt, Wolfgang1 aHolbourn, Ann1 aRegenberg, Marcus1 aAndersen, Nils  uhttps://ipaeg.myspecies.info/content/indonesian-throughflow-variability-through-makassar-strait-during-last-glacial-cycle00526nas a2200121   4500008004100000245009700041210006900138100002100207700002100228700001800249700002000267856011700287       2013                        eng d00aTropical convection variability in the West Pacific Warm Pool since the Last Glacial Maximum0 aTropical convection variability in the West Pacific Warm Pool si1 aFraser, Nicholas1 aBolliet, Timothe1 aHolbourn, Ann1 aKuhnt, Wolfgang  uhttps://ipaeg.myspecies.info/content/tropical-convection-variability-west-pacific-warm-pool-last-glacial-maximum
