Seen from below, a Late Cretaceous Elasmosaurus glides across the bright circle of sky known as Snell's window, its 7-metre neck built from 72 vertebrae (only one other plesiosaur, Albertonectes, had more). The animal and two schools of fish are bare shirt in your chosen shirt colour, cut out of stippled rings of sunlit cream and sea teal that fade into rays of light. Head on the correct end, unlike Edward Drinker Cope's first reconstruction, which put the skull on the tail. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
