The Brachiopod field of the Fossils section should be used to record any observation of fossil brachiopods.
Brachiopods are marine animals with a hinged, two-part shell on the top and bottom as opposed to the left and right arrangement of clams. They are, therefore, a bivalve but are not really related to other bivalve mollusks. Brachiopods also have a coiled, rigid cartilaginous internal structure called a lophophore, which sometimes appears in fossils.
Brachiopods and clams are sometimes difficult to distinguish as fossils. If the impression is bilaterally symmetrical, it is probably a brachiopod. If asymmetrical, it is probably a clam.
Brachiopod impressions can occur in large clusters.
