4.2 Amphibamus grandiceps
These two casts are of the anterior portions of two individuals. Amphibamus is a dissorophoid temnospondyl from the mid-Permian of North America. It is an interesting and important animal because dissorophoids have been suggested as potential ancestors of the frogs or perhaps all lissamphibians.
Note the structure of the skull, especially its large openings for the eyes etc. Compare one of these casts with one or more of the frog and salamander skeletons.
