Megalograptus ohioensis, a Late Ordovician sea scorpion from Ohio, swims through shallow water as a Japanese blue woodblock print, its giant spiny front limbs raised in a V and its oar-like paddles pulling it over a sea floor with a small trilobite, a stalked crinoid and brachiopods. At up to about 78 cm long it was one of the large predators of its sea about 445 million years ago. Two flat inks, Prussian blue and deep indigo, on Black, Sand, White, Military Green or Tropical Blue. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
