How to become a fossil in four steps, starring a Triceratops: die near water, get buried fast, let groundwater minerals move into the bone, then wait for a brush to find you. A vintage textbook engraving in one forest green ink, with a fern and horsetail riverbank, a cutaway of rock layers and magnified circles of bone turning to stone, highlights left as bare shirt (best on White or Sand). Results may take millions of years; for a Late Cretaceous Triceratops, at least 66 million. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
