Eurypterus remipesDescription: While Eurypterids (“Sea Scorpions”) are uncommon fossils worldwide, New York state is one of the few places where conditions for preservation have beenEurypterids ideal. They were large arthropod predators during the Silurian and Devonian, reaching a maximum length of 2 meters. The Eurypterid colonies of New York are distinctly localized, with two being found above and two below the salt beds of what was termed the Salina Series. These colonies are presumed to be breeding pools of brackish to partly open basins. They are the Otisville Basin (Colony O), the Pittsford Pool (Colony P), the Herkimer Pool (Colony P), and the Eurypterus remipes  Silurian Eurypterid Sea Scorpion from New YorkBuffalo Pool (Colony P). These last two are the most Sea Scorpion Scientific Illustrationfamous of them, yielding numerous fantastic specimens. Erypterus remipes was a small example of the Merostomata, with specimens having been found ranging from 8 mm to 280 mm in length. It is presumed to have crawled along the seafloor, using its grasping pincers to seize trilobites and other prey. This fine example is an adult, and has the swimming paddles and some walking legs preserved. Notice the compound eyes and detail to the prosoma. Much of the exoskeleton is preserved, the segmentation of the meso- and metasoma is well detailed, and the specimen is well-centered on the large dolostone matrix. What makes this one most unusual is the fact that it is preserved as a part/counterpart pair with a degree of 3D presence. This is a fine example of the fossil designated the New York State Fossil by then Governor Mario Cuomo in 1984.
