This retro, distressed black-and-white streetwear design features Dunkleosteus, a massive armored placoderm fish from the Late Devonian Period, shown bursting through stylized waves with bold Japanese-inspired typography. The monochrome white artwork on a black shirt gives it a vintage natural history poster feel while highlighting one of the Paleozoic seas’ most formidable apex predators. Made from 100% ring-spun cotton (high-quality cotton) with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
