Synopsis The phylogeny of a broad selection of taxa at the base of the monophyletic Eurypterina (swimming eurypterids) is analysed. The results suggest that Onychopterella is the most basal of these forms, in agreement with its early stratigraphic occurrence. One step up from Onychopterella is a split between the superfamily Eurypteroidea and a clade comprising the four other clades in Eurypterina: Mixopteroidea, Waeringopteroidea, Adelophthalmoidea and Pterygotoidea. Eurypteroidea is composed… Expand
