The paper "A revised chronostratigraphic framework for the Aptian of the Essaouira-Agadir Basin, a candidate type section for the NW African Atlantic Margin" by Tim Luber et al. has recently been published in Cretaceous Research (click link for online version). Mike Bidgood of GSS Geoscience Ltd. and Mike Simmons of Neftex/Halliburton carried out foraminiferal analysis of field samples as part of an integrated study examining biostratigraphy (forams, nannofossils and ammonites), chemostratigraphy, lithstratigraphy and sequence stratigraphy.
