This eurypterid fossil from New York State, USA, displays the distinctive form of an ancient animal commonly known as a sea scorpion. Its dark brown colouring contrasts beautifully with the pale grey matrix, drawing attention to the broad head shield, segmented body and curved, tapering tail.
The paddle-shaped swimming appendages are particularly eye-catching, extending beside the body and giving the specimen its unmistakable outline. The combination of visible anatomical detail and contrasting tones makes this an engaging display piece for a fossil collection or cabinet of natural curiosities.
This specimen offers an opportunity to explore a very different branch of prehistoric life, beyond the more familiar ammonites and trilobites.
Williamsville Formation, New York State, USA Upper Silurian 410 million years old
