4.3 Dissorophus multicinctus

This is the skull of a dissorophoid temnospondyl. Dissorophoids may have given rise to the ancestors of frogs, or perhaps all lissamphibians.

Note the presence of large palatal vacuities. Identify the other major openings in the skull (what is the most posterioropening on the side of the skull, immediately behind the eye?).
