The fauna may have originated during the Eocene–Oligocene. Because there are only a few taxonomic studies on Eocene–Oligocene ostracod taxa in the North Atlantic deep-sea sediments, the ostracod taxa are poorly understood. Here I report and illustrate 23 taxa from the upper Eocene–lower Oligocene sediments at Integrated Ocean Drilling Program Site U1411 in the North Atlantic Ocean and describe the taxa systematically. ¹ Yamaguchi, T., 2018.
