Griphognathus

Griphognathus (from Greek: γρίφος grífos 'riddle') and Greek: γνάθος gnáthos 'jaw') is an extinct genus of lungfish from the late Devonian period of Europe and Australia.

Griphognathus was a specialized lungfish, about 60 centimetres (24 in) long, with an elongated snout.

The lower jaw and palate were lined with tooth-like denticles.

Like all other lungfish, its skin was covered by overlapping scales, and it had an asymmetrical tail.
