Below is a full systematic list of known eurypterid species. I aim to keep this list updated as new discoveries and revisions occur, and to produce further pages of information for each rank to genus level. Anyone unfamiliar with binomial classification or Linnaean hierarchy can look here to see the layout explained. Click on a name to see further details.
