Excerpt: Pterygotus (meaning wing-animal or finned one) is the second-largest known eurypterid, or sea scorpion and one of the largest arthropods of all time. Pterygotus and Eurypterus viewed from abovePterygotid eurypterids, which lived from the Early Silurian to Devonian periods, were characterized by small to large exoskeletons with semilunar scales. The telson (tail) was expanded, or flatter than it was tall. Pterygotids also had chelicerae (claws in front of the mouth) that were large and long, with strong, well developed teeth on the claws.
