Coquina is a sedimentary rock that is composed either wholly or almost entirely of the transported, abraded, and mechanically-sorted fragments of the shells of molluscs, trilobites, brachiopods, or other invertebrates

European Foreland Basins

Unknown

From Concha (Latin)+ Coquina(Spanish) +conch(English)= Couquina (mid 19th century)
