Rhinodipterus is an extinct genus of prehistoric dipnoan sarcopterygians or lobe-finned fish, that lived in the Devonian Period, between 416 and 359 million years ago. It is believed to have inhabited shallow, salt-water reefs, [1] and is one of the earliest known examples of marine lungfish. Research based on an exceptionally well-preserved specimen from the Gogo Formation of Australia [2] has shown that Rhinodipterus has cranial ribs attached to its braincase and was probably adapted for air-breathing to some degree as living lungfish are. [3] This could be the only case known for a marine lungfish with air-breathing adaptations. [4]
