... carbonate producers may be sensitive to OA. To test this hypothesis, we constructed the first high-resolution, high-precision planktic foraminiferal δ 44/40 Ca records before and across the PETM. The records employ specimens of Morozovella spp. collected from Ocean Drilling Program Sites 1209 (Shatsky Rise...

... by the lensiformis-aragonensis-causcasica morphotypes. The morozovellids became extinct in the early middle Eocene with the LAD of M. aragonensis, which marks the top of Zone E9. In this chapter we discuss the taxonomy, biostratigraphy and phylogenetic relations of eight species of Morozovella which...
