Bivalve shell

Bivalve rarity 

This is the shell of a very rare bivalve species. It is possibly the third of its kind known in the world, and the first from Dorset.

As the name suggests, bivalves consist of two shells. ‘Bi’ means two and ‘valve’ means shell. The shells are held together by a strong muscle, and hinged at the pointed end.
