5.9" Eurypterus (Sea Scorpion) Fossil - New York
This is a very nice, 5.9" long Eurypterus remipes from Lang's Quarry in New York. It's pretty good sized, with both paddles and tail intact. There is a little bit of repair work to the head where a flake a shale was glued back down. Overall an excellent specimen.
Eurypterids, commonly known as Sea Scorpions are an extinct group of arthropods that are related to arachnids and include the largest known arthropods to have ever lived. Prevalent during the Silurian and Devonian, eurypterids were segmented aquatic arthropods, with compound eyes, and two club-like "arms." Some species exhibit toothed claws, and may therefore have been predators.
