eurypteridMember of an extinct order (Eurypterida) of arthropods, similar in body plan to the horseshoe crab, that lived c. 505–245 million years ago. Frequently referred to as giant scorpions, most eurypterids were small, although Pterygotus buffaloenis, a species from the Silurian period, was the largest arthropod ever known, reaching a length of about 10 ft (3 m). The eurypterids lived in brackish waters. Some were predators; others were probably bottom-dwelling scavengers. Want to thank TFD for its existence?
