 A taxonomic study of larger foraminifera in Paleocene rocks from the Pyrenean basin led to the description of 60 taxa, including two new species, and a chronostratigraphic recalibration of the Paleocene shallow benthic zones, SBZ1 to SBZ4, based on correlation with calcareous nanofossil and planktic foraminifera biosomes. The results show that the SBZ1 is defined by an association of non-exclusive taxa, while the SBZ2 is characterized by distinct larger foraminifera biomarkers. The SBZ3-SBZ4 boundary coincides with the base of the Solandian stage, and the SBZ4 biozone appears characterized by glomalveolina levis and alveolina corisensis. This article was authored by J.
