New York State Fossil - Eurypterus Remipes

Eurypterus Remipes, an extinct relative of the modern king crab and sea scorpion, was adopted as the State fossil in 1984.

During the Silurian Age (over 400 million years ago), Eurypterus Remipes crawled along the bottom of the shallow, brackish sea that covered much of New York, extending from Buffalo to Schenectady and south to Poughkeepsie, roughly along the route of the New York Thruway.
