Thalassionema bifurcum sp. nov., a new stratigraphically important diatom from Pliocene subantarctic sediments

A new diatom species Thalassionema bifurcum Kato et Suto is described from Pliocene subantarctic deep-sea sediments (DSDP Site 513 and IODP Site U1371). The stratigraphic occurrence of T. bifurcum is likely to be confined to the early Pliocene and shows remarkably high abundance (often comprising 50...
