Stratigraphy and Taxonomy of Cenozoic Radiolaria

这些项目建议继续进行一项长期项目，以修改大多数放射虫类群的分类系统（主要是在科和属水平上），并确定新定义类群的地层范围。这一大型数据集是根据深海钻探项目和海洋钻探项目在整个海洋中收集的岩心研究汇编而成的。拟议的研究将涉及一组介于PI先前研究的其他两组之间的放射虫。这项研究的结果将提供一个更清晰的认识，随着时间的推移，在一个重要的群体的物种形成的性质。

The PIs propose to continue a long-term project to modify the taxonomic system (mostly at the family and generic level) of most radiolarian groups and to determine the stratigraphic range of the newly defined groups. The large data set is being compiled from studies of Deep Sea Drilling Project and Ocean Drilling Program cores collected throughout the ocean. The proposed research will deal with a group of radiolarians intermediate between two other groups previously studied by the PI. The results of this study will provide a clearer understanding of the nature of speciations through time in an important group of microplankton.
