Prevalent during the Silurain and Devonian ages, eurypterids were segmented aquatic arthropods, with compound eyes, and two club-like "arms." These extinct creatures are related to today's horseshoe crab, and the fossil trilobite. Like trilobites, eurypterids shed their chitin-covered exoskeleton as they grew. Some species exhibit toothed claws, and may therefore have been predators.

Eurypterus remipes is the state fossil of New York, and some of the finest specimens ever recovered have been excavated from our private quarry in New York. To learn more about eurypterids, please visit our gallery and educational sections.
