Foraminifera are marine unicellular micro-organisms with a test. They have two essential characteristics: their small size and their abundance. They are represented by more than 10000 living species and more than 50000 fossil ones. The nature and the morphology of their tests formed the primary basis for their systematics recently supplemented by major achievements in molecular biology. Foraminifera display a wide range of lifestyles: they are abundant and diverse in modern oceans from the coastal zone to the deep sea. They occupy all environments and use various trophic mechanisms. In the geological archives, their analysis in the sediments quickly allows to understand past changes in marine environments. Their mineralized tests are generally very well preserved in sediments and easy to determine and a precious support for geochemical measurements (stables isotopes, elemental ratio), making them a prominent tool for sedimentary basin analysis. They are the most widely used organisms for biostratigraphy, dating, correlations and palaeo-environmental and climatic interpretations. Authors are invited to submit abstracts that contribute to the main topics of this session, focusing on recent improvements in taxonomy, phylogeny, biostratigraphy, biocorrelations, palaeo/climatology and palaeo/biogeography.
