Cenozoic Benthic Bathyal Foraminifers of DSDP Site 548 (North Atlantic)
Benthic foraminifers from the size fraction greater than 63μm were studied in 54 samples from the late Paleocene-Quaternary sequence of DSDP Site 548. In total 362 taxa were identified, 103 of which were considered as the most representative. Clustering of the samples on the basis of these foraminif...
