development in the region (WILSON 2008). No intervals of accelerated extinction have yet been discovered
in the Southeast Asian Neogene, suggesting that the high diversity of the regional reef biota is a function of
continuous diversification. These results suggest that the regional response of coral reef ecosystems to
global environmental change is strongly modulated by regional historical factors. Attempts to understand
long-term global patterns of diversity and ecosystem distributions are enhanced by analysis of variation at
non-global scales.

New initiatives that are currently in progress include study of large new collections from well localized
samples within well-resolved stratigraphic frameworks including a study of a new Late Oligocene biota
from Malaysian Borneo (MCMONAGLE et al. 2011) and the Throughflow Marie Curie Initial Training
Network, a large-scale collaborative project supported by the European Union to study the Miocene
shallow marine ecosystems of East Kalimantan (http://ipaeg.org/throughflow). The throughflow project
includes partners from 9 institutions in Europe and Indonesia, including a range of sub-projects designed
to independently reconstruct the geological, environmental, and biotic history of the Indonesian
Throughflow (ITN) within a well constrained stratigraphic framework. This project has completed two 5week
long field seasons in East Kalimantan and is currently processing samples. Access to this much
needed new information will allow for the first time a rigorous analysis of changing patterns of reef-coral
diversity in the Neogene of SE Asia.
