Climatius reticulatus
Climatius reticulatusClimatius reticulatus navigated Early Devonian shallows using pairs of sharp intermediate spines along its belly to deter prowling predators. Large forward-facing eyes and delicate tooth whorls suggest an active, visual hunter searching murky lakebeds and estuaries for tiny aquatic prey. Specimens preserved in Old Red Sandstone reveal heavily armored shoulder girdles that anchored rigid, spine-supported fins designed for rapid bursts of speed.
