Mosasaurus Scrimshaw Breaching T-Shirt

This vintage scrimshaw-style Mosasaurus t-shirt features a distressed sepia-brown nautical illustration on a white shirt, with a breaching marine reptile, ocean waves, map details, rope border, and compass rose. The design highlights Mosasaurus hoffmannii, the “Sea Dragon of Maastricht,” from the Late Cretaceous around 66 million years ago, giving it a classic natural history expedition feel. 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.
