       Pteroplax was an eogyrinid reptiliomorph that lived in England during the Carboniferous period.‭ ‬Like relative genera,‭ ‬Pteroplax had an elongated narrow body with reduced limbs.‭ ‬This kind of body enabled Pteroplax to squeeze in‭ ‬between tight spaces and obstacles to hunt down prey such as fish and small amphibians.
