Chasmosaurus strides across the chest in navy engraving above a museum-label fact box: lived 76 to 75 million years ago, about five metres long, family Ceratopsidae, a plant-eating relative of Triceratops best known for its enormous skin-covered frill framed by bone. The name means opening lizard, after the huge windows in that frill, which kept the whole billboard light enough to carry. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
