Radiolarian biostratigraphy

Radiolarians  are single celled, animal-like protists related to the amoeba but unlike amoeba they have internal mineralisation of opaline silica tests (shells).  They are diverse and widespread. In many places in the ocean they are so abundant that they pave the sea bottom with trillions of their tiny tests. In the Tectonics and Biostratigraphy Research Group we study their primary morphological characteristics, providing both a basis for their classification and an insight into their ecology.
