 The study of shells, called conchology by some and malacology by others, has been tied to the beginning of human civilization. Prehistoric man used molluscs for food, tools, weapons, currency, trade and decorations. Shell remains have been found in Neolithic kitchens and grave sites. Large gastropods were used as pots, bowls and ladles. Bivalves halves were probably used as scoops bowls and spoons. Shells were even cut into hooks for fishing. Several of the largest gastropod shells were used as trumpets and horns by people throughout the world. Excavations of prehistoric man's cemeteries have revealed that shells were the first good-luck charms and that cowrie shells were the earliest form of currency. Some of these pierced beads resemble the currency manufactured by the Natives of the Pacific and Atlantic coasts of the US, called Wampum. Wampum was manufactured from the shells of the Hard Clam, Mercenaria.
Fish Fossils: During the Eocene Period some 55-34 million years ago, in the Green river region of Wyoming. Millions of years ago it was not uncommon for torrential rains. The rain would flow down the mountain sides and then wide shallow lakes would form in the valley below. When the dry season would occur these lakes would dry up due to evaporation. Millions of fish would die in this short period of time. This climatic cycle happened over a 20 thousand year period. Layer upon layer of mud was deposited over these years entombing all these fish. At a much later date volcanic activity uplifted this area to expose all those layers of fossil fish in sandstone.
