| Outline of Final Research Achievements |
Cretaceous closed Nassellarian genus Turbocapsula exhibits an evolutionary lineage, showing phylogenetic changes in skeletal morphology, which was clarified by our research in southern Tibet, China. Two species within recent Nassellarian genus Eucyrtidium show a variation in pore arrangement, which is a family-level difference in radiolarian taxonomy.
The 15th International radiolarian meeting was held in Niigata in 2017. This meeting contributed not only to scientific field but also to outreach activities using enlarged models of radiolarian skeletons produced by macro-CT technique and 3D printing methods.
