Eurypterids (sea scorpions) are an extinct group of arthropods related to arachnids, which include the largest known arthropods that ever lived. They are members of the extinct class Eurypterida (Chelicerata). The word Eurypterid comes from the Greek word eury meaning "broad" or "wide" and the Greek word pteron meaning "wing".
He recognized the arthropod nature of the first ever described eurypterid specimen, found by Dr. S. L. Mitchill. James Lamsdell dug into the curious case of a 340 million-year-old sea scorpion, or eurypterid, originally from France that had been preserved at a Glasgow, Scotland museum for the last 30 years. Eurypterid Fossils 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. In recent years a commercial fossil quarry at Passage Gulf in Herkimer County has yielded many exceptional eurypterid fossils (Langs Fossils).

Eurypterids - The New York State Fossil The eurypterids were a group of Paleozoic arthropdods belonging to the subphylum Chelicerata, i.e. they are characterized by a first pair of appendages (the chelicera) located in front of the mouth. An additional five pair of post-oral appendages are present.

N ew York State Fossil: Sea Scorpion . Eurypterus is an extinct genus of sea scorpions. They existed during the Silurian Period, from around 432 to 418 million years ago. There are fifteen species belonging to the genus Eurypterus, the most common of which is Eurypterus remipes, the first eurypterid fossil discovered and the state fossil of New York.
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.

Langs, yes. I also this past weekend met a geologist who's particular fossil interest is Eurypterids, a good friend of Mr Nardi, Mr Lang's predecessor, and might get together with him to dig in a couple of spots in NY. He has a permit to dig on NYS Thruway property, so I will let you know if/when I go eurypterid hunting again. Did you scroll all this way to get facts about eurypterid fossil? Well you're in luck, because here they come.

Eurypterida. : Fossil Record. The first eurypterid fossils were discovered in 1818 by S. L. Mitchell in Silurian rocks of New York state. Mitchell mistook the fossil for a catfish, and it was not until 1825 that eurypterids were recognized as a group of arthropods.

Fossil eurypterid (sea scorpion) Dolichopterus macrocheirus from the Silurian of Herkimer County, New York (PRI 42894). Specimen is on display at the Museum of the Earth, Ithaca, New York. Length of preserved portion of specimen is approximately 18.5 cm in length. 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." Eurypterus is perhaps the most well-known genus of eurypterid, of which 18 fossil species are known. The genus Eurypterus was created in 1825 by James Ellsworth DeKay, a zoologist.
