A genus of extinct arthropods from the Triassic period, primitive forms related to modern crustaceans.
From Greek eryon, meaning 'shrimp' or 'prawn.' The scientific genus name preserves this ancient Greek term to classify these fossil creatures.
Eryon fossils show us what Earth's oceans looked like 200 million years ago—these ancient crustaceans survived when dinosaurs roamed the land, and some of their living relatives are still scuttling around oceans today.
