Stegotrachelus is an extinct genus of prehistoric bony fish that lived during the Middle Devonian epoch in what is now Shetland, Scotland. [1]
Luckeus is an extinct genus of prehistoric lobe-finned fish. Luckeus belonged to the order Onychodontida. It lived during the Early Devonian to Middle Devonian period in what os now central Australia.
Miguashaia is a genus of prehistoric lobe-finned fish which lived during the Devonian period. Miguashaia is the most primitive coelacanth fish.
Gogodipterus is an extinct genus of prehistoric lungfish in the family Chirodipteridae. It was discovered ar the Late Devonian Gogo Formation of Western Australia.
Glyptopomus 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.
Cryptolepis is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Latvius is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Iowadipterus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Heimenia is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Oervigia is an extinct genus of lungfish in the family Rhinodipteridae from the Devonian of Greenland.
Muranjilepis is an extinct genus of prehistoric sarcopterygians or lobe-finned fish.
Pillararhynchus is an extinct genus of prehistoric sarcopterygians or lobe-finned fish.
Pentlandia is an extinct genus of prehistoric sarcopterygians or lobe-finned fish. Its first discovered species was initially named Dipterus macroptera by Ramsay Traquair in 1888, then renamed Pentlandia macroptera by D.M.S. Watson and H. Day in 1916.
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.
Tarachomylax is an extinct genus of prehistoric sarcopterygians or lobe-finned fish.
Scaumenacia is an extinct genus of prehistoric 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.
Holopterygius is an extinct genus of prehistoric eel-like coelacanth known from the Devonian (Givetian–Frasnian) of Germany. Despite its specialized morphology and superficial dissimilarity to the usual Paleozoic coelacanth body plan, it is one of the most basal actinistian fish.
Ligulalepis is an extinct genus of prehistoric bony fish. Ligulalepis was first described from isolated scales found in the Taemas-Wee jasper limestones of New South Wales by Dr Hans-Peter Schultze (1968) and further material described by Burrow (1994). A nearly complete skull found in the same general location was described in Nature by Basden et al. (2000) claiming the genus was closely related to basal ray-finned fishes (Actinopterygii). In 2015 Flinders University student Benedict King found a more complete new skull of this genus which was formally described by Clement et al. (2018), showing the fish to be on the stem of all osteichthyans.
Mimipiscis is a fossil genus of very primitive ray-finned fishes from the Upper Devonian Gneuda and Gogo formations of Western Australia.
