Lochmocercus is an extinct genus of prehistoric coelacanth fishes which lived during the Carboniferous Period. [1] [2]
The Bear Gulch Limestone is a limestone-rich geological lens in central Montana, renowned for the quality of its late Mississippian-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.
Falcatus is an extinct genus of falcatid chondrichthyan which lived during the early Carboniferous Period in Bear Gulch bay in what is now Montana.
Allenypterus is an extinct genus of coelacanths which lived during the Bashkirian age 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 (Induan), and its fossils have been found in Europe, Madagascar and North America. The type species was originally described as Coelacanthus elegans. Five species are considered valid in 1981.
Caridosuctor is an extinct genus of marine coelacanth that lived during the Carboniferous period. It contains a single species, C. populusum, with fossils known from the Bear Gulch Limestone in Montana.
Rhabdodermatidae is a family of prehistoric, coelacanthimorph, lobe-finned fishes which lived mainly during the Carboniferous period, with some members surviving until the Early Triassic epoch.
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.
Laugiidae is an extinct family of prehistoric marine coelacanths which lived during the Triassic and Jurassic periods. Their fossils have been found in Canada, Germany and Greenland.
Mordex is an extinct genus of temnospondyls from Carboniferous of the Czech Republic.
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.
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 southern Switzerland.
Hainbergia is an extinct genus of prehistoric sarcopterygian or lobe-finned fish.
Mylacanthus is an extinct genus of prehistoric coelacanth lobe-finned fish that lived during the Smithian age of the Early Triassic epoch in what is now Svalbard.
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.
Cyranorhis is an extinct genus of prehistoric marine ray-finned fish that lived during the Serpukhovian age of the Carboniferous period. One species is known, C. bergeraci in the Bear Gulch Limestone what is now Montana, United States. It is named after French novelist Cyrano de Bergerac.
Cycloptychius is an extinct genus of prehistoric freshwater & marine ray-finned fish that existed throughout much of the Carboniferous period in Eurasia, and possibly into the Early Permian in South Africa. It was a member of the Rhadinichthyidae, a family of basal ray-finned fish that was formerly placed in the now-paraphyletic order Palaeonisciformes.
