(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>

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.
