Inspired by the ancient seas of the Late Cretaceous Period, the artwork combines paleontological accuracy with patriotic red, white, and blue tones for a bold natural history statement. 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.
