3" Eurypterus (Sea Scorpion) Head (Pos/Neg) - New York

This is a large, fossil Eurypterid head collected in the Buffalo, NY area. Both the positive and negative impressions of the fossil are included.



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.
