Classification Because of current database limitations that restrict the number of possible ranks between class and order levels, the parent-child relationships are displaying incorrectly in this entry. Heteroconchia consists of two subclades (Palaeoheterodonta and Heterodonta). Heterodonta is comprised of Archiheterodonta and Euheterodonta. The latter two should be at a rank lower than Heterodonta (e.g., “Parvclass”). [details]
