About the size of a bus, the Stegosaurus was plant-eating dinosaur that lived about 150.8 million to 155.7 million years ago. The plates on its back made it look even larger than it was. Both fun and sophisticated, these earrings are inspired by science and nature. The earring images are made from recycled cereal boxes (really!) making them eco friendly, and they are also stainless steel/hypoallergenic!
