Heterodonta is a subclass of bivalve molluscs, including the clams and cockles.[1] They are distinguished by having the two halves of the shell be equally sized, and having a few cardinal teeth separated from a number of long lateral teeth. Their shells lack a nacreous layer, and the gills are lamellibranch in form. Most species have a siphon.[2]
The subclass contains four extinct orders, five orders of living bivalves and a group of yet unassigned Euheterodonta:
- Order †Cycloconchidae
- Order †Hippuritoida (rudists)
- Order †Lyrodesmatidae
- Order †Redoniidae
