Radiolarians are marine planktonic protists that belong to the eukaryote supergroup Rhizaria together with Foraminifera and Cercozoa. Radiolaria has traditionally been divided into four main groups based on morphological characters; i.e. Polycystina, Acantharia, Nassellaria and Phaeodaria. But recent 18S rDNA phylogenies have shown that Phaeodaria belongs within Cerocozoa, and that the previous...
The Southern Ocean Radiolarian (SO-RAD) dataset: a new compilation of modern radiolarian census data
Abstract. Radiolarians (holoplanktonic protozoa) preserved in marine sediments are commonly used as palaeoclimate proxies for reconstructing past Southern Ocean environments. Generating reconstructions of climate based on microfossil abundances, such radiolarians, requires a spatially and environmentally comprehensive reference dataset modern census counts. The Radiolarian (SO-RAD) includes cou...
