The Copodontidae or Copodontiformes are an extinct group of cartilaginous fish , which is only known from finds of isolated fossil tooth plates and was only found in carbon . The nearly square tooth plates sat individually at the tip of the upper and lower jaw of the otherwise unknown fish.

It is believed that the Copodontidae are distant relatives of today's sea ​​cats (Chimaeriformes).
