Summary[edit]

Description

Eurypterus remipes DeKay, 1825 (7.5 cm across) - closeup of showing four walking appendages and swimming appendages (labeled) with paddles at distal ends.


The eurypterids, or sea scorpions, are an extinct group of chelicerate arthropods. They have an elongated, scorpion-like body that could reach enormous sizes (2.5 to 3 meters!), with a nonmineralizing exoskeleton composed of chitinous material. They are generally found in shallow to very shallow water marine and marginal marine facies.

Eurypterus remipes DeKay, 1825 is a classic example of this bizarre group of creatures. It, and other eurypterid species, is well represented in the famous Bertie Dolomite of New York State, USA.
