Mitchell mistook the fossil for a catfish, and it was not until 1825 that eurypterids were recognized as a group of arthropods.

Because of their long tails and the spine-like appendage at the tip, the eurypterids have been called sea-scorpions. Eurypterus is by far the most well-studied and well-known eurypterid and its fossil specimens probably represent more than 90% of all known eurypterid specimens. There are fifteen species belonging to the genus Eurypterus, the most common of which is Eurypterus remipes, the first eurypterid fossil discovered and the state fossil of New York.
