Thalassionema sp. A (Pl. P10, figs. 1–10).

Remarks: The valve of this taxon possesses slender and linear outline with slightly compressed and rounded ends that can easily be separated from other Thalassionema taxa with broadly rounded ends to lanceolate with subcapitate ends such as Thalassionema nitzschioides complex (Tanimura et al., 2007) and Thalassionema schraderi (Akiba, 1982b). The stratigraphic occurrence in Hole U1371D ranges from Samples 329-U1371D-9H-7W, 58–59 cm to 6H-6W, 81–82 cm (82.98–53.71 m CSF-A) with a distinct peak, where it comprises over 50% of diatom assemblage, at Sample 9H-1W, 92–93 cm (74.82 m CSF-A) (Fig. F2; Table T1). The high occurrence may correspond to the Thalassionema increasing event in 5.7, 5.2–4.7 and 4.4–3.7 Ma reported from the Antarctic Peninsula’s Pacific margin by Bart and Iwai (2012), although the taxa are differentiated. This taxon is potentially useful for diatom biostratigraphy, because it is relatively short-ranging with specific characteristics that allow for easy identification in practical stratigraphic analysis.
