Mosasaurus hoffmannii glides across a window of sunlit water in this two-ink print: cream and sea-teal waves above, rays fanning down past a school of fish. The mosasaur is bare shirt traced in cream, so it takes on your shirt colour. Its name means Meuse lizard, for the river near the Maastricht quarry where the first known skull was found in 1764. A marine reptile related to lizards and snakes, not a dinosaur, it grew up to 12 m long and hunted the last seas of the Cretaceous. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
