Bivalve (Pelecypoda) Fossil Sea Shell with Chalcopyrite | Mineralized Fossil Specimen | Indonesia Dogtooth Keep rough material out ofThis exceptional bivalve (Pelecypoda) fossil sea shell from Indonesia is a striking fusion of deep geological time and mineral transformation. Once a living marine organism, this shell has been preserved through fossilization and later enhanced by the natural crystallization of chalcopyrite, creating a stunning contrast between ancient biological form and metallic mineral growth. The fossil retains clear bivalve morphologyribbing, curvature, and shell
