Lyrolepis is an extinct genus of prehistoric ray-finned fish found in the Eocene Adaev Formation of Kazakhstan and the Pshekha Formation of Georgia. [1]
Kushlukia is an extinct genus of prehistoric bony fish, closely related to the luvar, that lived during the lower Eocene. K. permira is from Eocene portion of the Danata Formation Lagerstatten, of Turkmenistan. A second, as yet undescribed species is from the Fuller's Earth formation Lagerstatten in the Barmer District, of Ypresian Rajasthan, India.
Tharrhias is an extinct genus of prehistoric bony fish that lived during the Aptian stage of the Early Cretaceous epoch. The type species T. araripis is named after the Araripe Basin, in which it was found in sediments of the Santana Formation.
Araripichthys is an extinct genus of prehistoric ray-finned fish that lived from the Aptian to Coniacian stages of the Cretaceous period. The genus is named after the Araripe Basin, where it was found in the Crato and Santana Formations. Other fossils of the genus have been found at Goulmima in Morocco, the Tlayua Formation of Mexico and the Apón Formation of Venezuela.
Oshunia is an extinct genus of prehistoric bony fish that lived during the Albian. Fossils of the genus were found in the Romualdo Formation of the Araripe Basin, northeastern Brazil. Other authors assign a Cenomanian age to the fish.
Casierius is an extinct genus of prehistoric bony fish that lived during the Albian stage of the Early Cretaceous epoch. It is one of the oldest eels. The fossils of this animal were found in Glen Rose Formation near, Hood County, Texas.
Luisiella is an extinct genus of prehistoric bony fish that lived during the Kimmeridgian stage of the Late Jurassic epoch. Fossils of the genus have been found in either the Cañadón Calcáreo Formation or Cañadón Asfalto Formation in Chubut Province, Argentina.
Boreichthys is an extinct genus of prehistoric bony fish that lived during the Early Triassic epoch.
Helmolepis is an extinct genus of ray-finned fish that lived during the Early Triassic epoch in what is now Greenland, Madagascar and Canada. Species of Helmolepis are small. This genus is closely related with Platysiagum.
Brookvalia is an extinct genus of prehistoric bony fish that lived during the Early Triassic epoch.
Stichopterus is an extinct genus of chondrostean ray-finned fish that lived during the Early Cretaceous epoch in Asia. It has been found in Russia and Mongolia.
Cephaloxenus is an extinct genus of prehistoric bony fish that lived during the early Ladinian stage of the Middle Triassic epoch.
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.
Protautoga is an extinct genus of prehistoric ray-finned fish, that lived in the Middle Miocene. Fossils have been found in the Paraná Formation of Argentina and the Calvert Formation of Virginia.
