[[Image:JFR_cover.gif|left|80px| ]]<font size="3">Forty-nine species of organic-cemented siliceous agglutinated foraminifera are described from 11 different facies associations representing basinal deposits of the Triassic in Timor Leste. The facies associations containing the foraminifera range from those influenced by sediment derived from nearby carbonate banks to prodelta and delta-front associations. A survey of equivalent faunas from selected shallow-marine basins ranging from the Carboniferous to the mid-Cretaceous illustrates the conservative development through time of the siliceous agglutinated foraminifera.

Our data underline the necessity to base longer δ18O and δ13C isotope records derived from benthic foraminifera on size windows of 100 μm or less. This is already common practice in down-core isotopic studies of planktonic foraminifera.
