Plural of ampyx; a genus of extinct trilobite arthropods from the Paleozoic Era.
From Greek ampyx (unclear origin, possibly relating to 'both eyes' or visual characteristics). Scientific naming convention for a prehistoric creature group.
Ampyces trilobites had huge eyes for their time—by studying their fossils, paleontologists discovered that some ampyces species actually had the most advanced compound eyes of any Paleozoic creatures, allowing them to see in low light.
