Pentecopterus: History, Research & Art

Pentecopterus is a genus of eurypterid, an extinct group of aquatic arthropods. Fossils have been registered from the Darriwilian age of the Middle Ordovician period, as early as 467.3 million years ago. The genus contains only one species, P. decorahensis, that was previously considered the oldest known eurypterid, surpassing all other Ordovician…
