Bivalvia (/ b aɪ ˈ v æ l v i ə /) or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-shells known as valves.
The 2010 taxonomy is known as the Taxonomy of the Bivalvia (Bouchet, Rocroi, Bieler, Carter & Coan, 2010) [citation needed]. The 2010 taxonomy was published as Nomenclator of Bivalve Families with a Classification of Bivalve Families. [1] This was a revised system for classifying bivalve mollusks such as clams, oysters, scallops, mussels and so on.

One bivalve group, the rudists, became major reef-builders in the Cretaceous, but became extinct in the Cretaceous–Paleogene extinction event. [93] Even so, bivalves remain abundant and diverse. The Hyolitha are a class of extinct animals with a shell and operculum that may be molluscs.
Ostreoidea is a taxonomic superfamily of bivalve marine mollusc, sometimes simply identified as oysters, [1] containing two families. The ostreoids are characterized in part by the presence of a well developed axial rod. [2] Anal flaps are known to exist within the family Ostreidae but not within the more-primitive Gryphaeidae. [3]
