Taxonomy of the fossil marine diatom resting spore morpho-genera Xanthioisthmus Suto gen. nov. and Quadrocistella Suto gen. nov. in the North Pacific and Norwegian Sea
The morphology and taxonomy of the fossil diatom resting spore morpho-genera Xanthioisthmus Suto gen. nov. and Quadrocistella Suto gen. nov. are described. The two new genera are probably fossil resting spores of the marine diatom genus Chaetoceros . They were studied by examining samples from DSDP...
