Spiny Jewel Box Shells

Spiny jewel box shells.

 These are spiny jewel box shells, or Arcinella cornuta. they are bivalves. Bivalves are invertebrates with two shells. You can find their shells separate or together like the kitten paw shells. I have even found a fossilised one. My grandma calls them lion paw shells (to go with the kitten paws).
