Short summary

The Integrated Ocean Drilling Program Expedition 341 retrieved deep-sea sediment (e.g., U1417) for determining the linkage between climate and tectonism change in the Neogene at several sites. It is crucial to constrain the age of the collected sediments. In this context we define the biostratigraphy of radiolarians, which are a good proxy for constraining the age of deep-sea sediments. We defined the upper 200 m of the core sediments collected at Site U1417 as covering the past 1.7 Mky.
