Cambrian bivalved arthropods are a group of arthropods characterized by their cephalothoracic bivalved carapaces. Many bivalved arthropods are known only from isolated carapaces, but fossils with soft tissue preservation are revealing an increasingly complex group, mostly comprising the stem-group euarthropod Isoxyidae (Aria and Caron, 2015) and the Hymenocarina. Four Paleozoic bivalved genera are assigned to the new molluscan class Rostroconchia: Eopteria, Euchasma, Conocardium, and Pseudoconocardium.These mollusks have an uncoiled univalved larval shell; an untorted bivalved adult shell; no hinge teeth, ligament, or adductor muscles; and a fused, almost inflexible. hinge.Clam, in general, any member of the invertebrate class Bivalvia—mollusks with a bivalved shell (i.e., one with two separate sections).
