Caspiodontornis
 Caspiodontornis is a doubtfully valid genus of the prehistoric pseudotooth birds of somewhat doubtful validity. These were probably rather close relatives of either pelicans and storks or of waterfowl and are here placed in the order Odontopterygiformes to account for this uncertainty.Only a single species Caspiodontornis kobystanicus is known to date. Its remains – a fairly complete skull and beak – were found in early Late Oligocene (Chattian MP25-30) rocks at Pirəkəşkül (Azerbaijan).
