Eurypterus was 20–25 cm long and 6–7 cm wide.

Eurypterids, or sea scorpions, were a group of arthropods whose closest modern relatives are horseshoe crabs. They were fierce predators that lived in the ocean, estuaries or rivers. The eurypterids that ventured out of the water were among the first animals to walk on land. Some eurypterids were enormous – the biggest was over two metres long.
