This retro natural history design celebrates Tiktaalik, the iconic transitional fossil from the Late Devonian Period (~375 million years ago), often considered one of the key evolutionary links between fish and early land vertebrates. The vintage, slightly distressed artwork features a playful Tiktaalik beneath a crescent moon with earthy brown and burnt-orange tones that stand out against the soft sand-colored shirt, blending science with a whimsical prehistoric vibe. 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.
