(2003) are the main components of shallow coral reef environments. Their status as a monophyletic subfamily is lost, but different subsequent proposals about the taxonomic relationships of their genera were declared to be untenable. Here we present a new, more complete phylogeny of Mastophoroideae sensu Harvey et al. (2003) with a temporal dimension reflecting the evolutionary history of this clade which is very important in ecological and structural means in coral reefs. We agree with Kato et al. (2011) to maintain the Lithophylloideae, Corallinoideae and Metagoniolithoideae, to reduce the Mastophoroideae and to establish the new subfamilies Hydrolithoideae, Neogoniolithoideae and Porolithoideae. We propose two new genera Adeylithon gen. nov. with the type species A. conicum and Harveylithon gen. nov. with the type species H. rupestre. The calibration of the molecular clock of the genetic marker SSU supposes a Cenozoic origin of most of the clades of the former mastophoroids sensu Harvey et al. (2003) and a separation from Hapalidiaceae in the boundary between early and late Cretaceous.</p>

To date, however, comprehensive analyses of biotas and biofacies of Indo-West Pacific reefs that developed in mixed carbonate-siliciclastic systems are lacking. This study describes the palaeoenvironment and biodiversity of a late Burdigalian patch reef that developed in a mixed carbonate-siliciclastic depositional system. The studied exposure is located at the northeast margin of the Kutai Basin near Bontang (Indonesia), and is approximately 80 m wide and 25 m thick. Multi-taxon analysis of the most abundant fossil groups, including larger benthic foraminifera, corals, coralline algae, and bryozoans, aims to provide a model for environmental interpretation that will allow comparison with similar deposits of Indo-West Pacific region. Based on fossil content and lithology, five different facies types have been distinguished: foraminiferal packstone (FP), bioclastic packstone with foralgal communities (BP), thin-platy coral sheetstone (CS), platy-tabular coral platestone (CP), and shales (S). Among larger benthic foraminifera, smaller and more robust forms dominate in the FP and BP facies, while larger and flatter forms are the most abundant in the CS and CP facies. Thin-platy corals are dominant in the CS facies and gradually change into thicker platy-tabular forms in the CP facies. Assemblages and growth forms of coralline algae show no major differences between the facies types and are dominated by melobesioids and Sporolithon. The majority of bryozoan species are encrusting and were found only in the CS facies. Light-dependent organisms occurring in the reef indicate low light conditions typical for mesophotic reefs. The relatively small size of this reef complex and quite distinct vertical changes in the facies types, combined with the high siliciclastic content in most of the units, points to strong terrigenous input affecting water transparency as the main factor controlling the reef growth.</p>

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.

The factors responsible for the origins and maintenance of this diverse biota remain unknown. Previous studies suggest that the formation of the ancestral centre of diversity could be related to the constriction of the Indonesian Throughflow current (ITF) during the Cenozoic, resulting in increased speciation and/or immigration during the Miocene. Unfortunately, the fossil evidence currently available to document this pattern and its geographic context is sparse, and there is a need to collect new data.

The scientific objective of the THROUGHFLOW Project is to reconstruct the biological and environmental history of shallow marine habitats of a selected area of Southeast Asia. Specifically, a multidisciplinary study of key sections in Eastern Kalimantan (Indonesia) will be performed, integrating data from geology, geochemistry, ocean modeling, and paleontology to understand the Neogene history of the region.

In this framework, the projects carried out at Granada University aim to document the timing and patterns of the diversification of Indo-Pacific reef-building coralline algae, the second most important builders in modern Indo-Pacific reefs. The collected data will be integrated with a robust sedimentological framework for detailed reconstructions of the shallow marine carbonate paleoenvironments and their evolution through time.

The first expedition has been already carried out in East Kalimantan (Indonesia) during November-December 2010. A variety of shallow marine ecosystems, including coral reefs and sea grass environments, were found. First results show an exceptional preservation of some fossil algae, especially in places with a high siliciclastic influence (Miocene deposits of the Mahakam Delta). A new expedition is scheduled for summer 2011. We will study a wider temporal (Early to Late Miocene and possibly Late Oligocene) and spatial range of outcrops.
