A4 Stratigraphy and Ecology of Cenozoic Larger Benthic Foraminifera

Summary

Larger benthic foraminifera (LBF) have been paramount for the development of biostratigraphy in shallow marine (sub)tropical environments. Following the definition of the Shallow Benthic Zones, more than ten years ago by Cahuzac and Poignant (1997) and Serra-Kiel et al. (1998), a wealth of new data have become available on the occurrence of LBF, the integration of stratigraphical data from different sources, the development of Cenozoic paleogeography and climate, as well as new morphological investigation methods. During the early part of the past 65 million years the world looked very different from the world we know today. In the Eocene tropical climates reached north to southern England (Pearson et al. 2007), there was a wide seaway between Africa and Eurasia (Dercourt et al., 2000) and there were numerous smaller or larger carbonate platforms in what is now the circum-Mediterranean area (Popov et al., 2004). Likewise, biodiversity was very differently distributed than today, with the most diverse communities along the northern shores of the western Tethys (Renema et al. 2008). With this special session we aim at bringing together specialists in the fields of stratigraphy, phylogeny and systematics of larger benthic foraminifera, paleoclimate and paleobiogeography, to: 1) synthesize the developments of the past ten years, 2) make an inventory of the available data and gaps in our knowledge in order to update the shallow benthics zonation, and 3) improve our understanding of the biological response to major climatic and paleogeographic transitions, and and 4) improve the phylogenetic models combining morphometric and molecular genetic investigations.
