Horoscope: Aries Pachycephalosaurus T-Shirt

This retro natural history design pairs the Aries zodiac theme with two head-butting Pachycephalosaurus, a dome-skulled dinosaur from the Late Cretaceous Period. The black line-art illustration on a cream shirt features botanical fossil-inspired foliage, constellation details, and a vintage scientific engraving style. 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.
