This fossil sea biscuit is a beautifully preserved example of an ancient echinoid, offering a window into prehistoric marine life. Sea biscuits are close relatives of sand dollars and belong to the order Clypeasteroida, a group of flat to slightly domed sea urchins that lived burrowed within sandy ocean floors.
While sand dollars are typically very flat, sea biscuits are thicker and more rounded in form. Around the world, these animals are known by many names, including sand cookies, sand cakes, cake urchins, snapper biscuits, and pansy shells, reflecting their wide distribution and long history in coastal environments.
Fossil sea biscuits showcase the distinctive star shaped pattern on their surface, a hallmark of echinoids that once used tube feet for movement and feeding. This specimen makes an excellent addition to any fossil collection and is also well suited for educational displays or natural history inspired decor. Each fossil is unique, preserving the subtle details of an organism that lived millions of years ago on the ocean floor.
