Schizodus^[1] is an extinct genus of shallow marine clams. It lived from the Silurian to Late Permian periods.^[2]

Schizodus represents the primitive stage of schizodonts, clams having reverse V-shaped scissurate hinge teeth (still triangular in Schizodus), and often an elongated lateral tooth.^[3]
