Brachiopods, Lower Carboniferous


A fossilized marine invertebrate of the phylum Brachiopoda, which comprises the lamp shells.

The word "brachiopod" is formed from the Ancient Greek words βραχίων ("arm") and πούς ("foot").[3] They are often known as "lamp shells", since the curved shells of the class Terebratulida look rather like pottery oil-lamps.
