Heterodonta

Belongs within: Bivalvia.
Contains: Hippuritacea, Psammobia, Neomiodontidae, Carditoidea, Crassatelloidea, Anomalodesmata, Panopea, Gastrochaenidae, Tellinoidea, Cardiidae, Chama, Lasaeidae, Lucinidae, Galeommatidae, Pholadoidea, Solenoidea, Mactroidea, Dreissenidae, Myoidea, Sphaeriidae, Corbiculidae, Veneridae.

The Heterodonta are one of the major living clades of bivalves, with their earliest representatives appearing in the Ordovician. In the past, the living members of the clade were divided between the orders Veneroida and Myoida (the latter including burrowing forms with thin shells and reduced dentition), but molecular analyses have indicated that the myoidans are polyphyletic (Giribet & Wheeler 2002). Instead, a clade containing the Carditoidea and Crassatelloidea appears to be the first group to have separated from the remaining heterodonts, followed by the Anomalodesmata (previously regarded as distinct from the Heterodonta).

Other groups within the Heterodonta include the Hiatellidae, a family of small, quadrate to trapezoidal, burrowing or nestling clams. The Galeommatoidea are burrowing clams with the shell commonly thin and more or less covered externally by the mantle.

Characters (from Cox et al. 1969, excluding Anomalodesmata in which many characters have become altered): Mantle lobes more or less joined and usually possessing developed siphons; cardinal area commonly present, prosodetic or divided into lunule and escutcheon; ligament opisthodetic, with or without separate resilium; without lithodesma and rarely with external accessory shelly pieces; nepionic stage usually without taxodont provinculum or adult byssus; generally possessing hinge plate and teeth differentiated into distinct cardinals and laterals; shell structure crossed lamellar, complex, or prismatic, never nacreous; gills eulamellibranchiate.
