Short summary
We described two new species of the fossil dinoflagellate cyst genus Svalbardella. S. clausii sp. nov. has a narrow range in the lowermost Chattian and may be related to cooler surface waters. S. kareniae sp. nov. ranges from Lower Oligocene to Lower Miocene and favours more open marine conditions. Our study illustrates the close phylogenetic relationship between Svalbardella and Palaeocystodinium and shows that surface ornamentation and the tabulation are variable features within both genera.
