Hainbergia is an extinct genus of prehistoric sarcopterygian or lobe-finned fish. [1] [2] [3]
Sarcopterygii — sometimes considered synonymous with Crossopterygii — is a clade of vertebrate animals which includes a group of bony fish commonly referred to as lobe-finned fish. These vertebrates are characterised by prominent muscular limb buds (lobes) within their fins, which are supported by articulated appendicular skeletons. This is in contrast to the other clade of bony fish, the Actinopterygii, which have only skin-covered bony spines supporting the fins.
Gavinia is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Ganopristodus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish from the Devonian.
Eoctenodus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Devonosteus is an extinct genus of prehistoric marine lobe-finned fish known from the Late Devonian. It contains a single species, D. proteus from the late Frasnian of Wildungen, Germany. It has sometimes been considered a lungfish of the family Holodontidae, but this remains uncertain as the original specimen may be lost. Alternatively, it may be a tristichopterid, a type of basal tetrapodomorph.

Megapleuron is an extinct genus of prehistoric sarcopterygian or lobe-finned fish that lived during the Asselian age of the Cisuralian epoch in what is now Burgundy, France.
Rhipis is an extinct genus of prehistoric sarcopterygians or lobe-finned fish.
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, 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 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. This could be the only case known for a marine lungfish with air-breathing adaptations.
Proceratodus is an extinct genus of prehistoric sarcopterygians or lobe-finned fish.
Orlovichthys is an extinct genus of prehistoric sarcopterygians or lobe-finned fish. Fossil evidence was found in Russia, and is from the Late Devonian period.
Tranodis is an extinct genus of prehistoric sarcopterygians or lobe-finned fish. It was a lungfish from the Upper Mississippian of North America.

Scaumenacia is an extinct genus of lungfish. It lived around the Devonian in North America alongside another prehistoric lungfish: Fleurantia. It lived from approximately 384 to 376 millions of years ago.
