Lochmocercus is an extinct genus of prehistoric coelacanth fishes which lived during the Carboniferous Period. [1] [2]
Actinistia is a subclass of mostly fossil lobe-finned fishes. This subclass contains the coelacanths, including the two living species of coelacanths, both of the genus Latimeria: the West Indian Ocean coelacanth and the Indonesian coelacanth.
The Bear Gulch Limestone is a limestone-rich geological lens in central Montana, renowned for the quality of its late Mississipian-aged fossils. It is exposed over a number of outcrops northeast of the Big Snowy Mountains, and is often considered a component of the more widespread Heath Formation. The Bear Gulch Limestone reconstructs a diverse, though isolated, marine ecosystem which developed near the end of the Serpukhovian age. It is a lagerstätte, a particular type of rock unit with exceptional fossil preservation of both articulated skeletons and soft tissues. Bear Gulch fossils include a variety of fish, invertebrates, and algae occupying a number of different habitats within a preserved shallow bay.
Allenypterus is a genus of a prehistoric lobe-finned fish which lived during the Bashkirian stage of the Late Carboniferous period, 318 million years ago). Fossils have been discovered in Bear Gulch Limestone, Montana, USA.
Rhabdoderma is an extinct genus of coelacanth fish in the class Sarcopterygii. It lived in the Carboniferous and Early Triassic, and its fossils have been found in Europe, Madagascar and North America.
Polyosteorhynchus is an extinct genus of coelacanth lobe-finned fish which lived during the Carboniferous period. The size of Polyosteorhynchus was about 3,5 – 19 cm long.
Diplocercidae is an extinct family of prehistoric coelacanth fishes which lived during the Devonian and Carboniferous period.
Hadronectoridae is an extinct family of prehistoric coelacanth fishes which lived during the Carboniferous period. However, according to Actinistia, it could include Laugiidae, Rhabdodermatidae and not extinct Coelacanthiformes.
Coelacanthopsis is an extinct genus of lobe-finned fish which lived during the Carboniferous period.
Ctenocephalichthys is an extinct genus of prehistoric ray-finned fish that lived during the Santonian.
Elonichthys is an extinct genus of prehistoric bony fish. The genus is represented by several species from Carboniferous and Permian of Europe, Greenland, South Africa, and North America.
Euporosteus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Cryptolepis is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Iranorhynchus is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Heptanema is an extinct genus of prehistoric coelacanth from the Middle Triassic (Ladinian) of northern Italy and Switzerland.
Hainbergia is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Mylacanthus is an extinct genus of prehistoric sarcopterygians or lobe-finned fish.
Sagenodus is an extinct genus of prehistoric lungfish. It is a lungfish from the Permo-Carboniferous period found in Europe and North America.
Paraceratodus is an extinct genus of prehistoric lungfish. Only one species, P. germaini, is known from the latest Permian or earliest Triassic period of Madagascar. Phylogenetic evidence supports it being the most basal member of the suborder Ceratodontoidei, which contains modern lungfish, and as with the rest of the order it likely diverged during the late Carboniferous.
Tarachomylax is an extinct genus of prehistoric sarcopterygians or lobe-finned fish.
Acondylacanthus is an extinct genus of Euselachian shark from the Paleozoic era. The type species is A.gracilis. Most species are known from the Carboniferous of America and the British isles. A. jaekeli is known from the upper Frasnian of Germany and the Upper Famennian of Russia. This genus is based entirely upon isolated dorsal fin spines, and thus may later be found synonymous with tooth-based genera. Many species have been ascribed to this genus, though there has been some confusion with Ctenachanthus. This genus is in need of review and research.
