Placopleurus is an extinct genus of prehistoric ray-finned fish from the Middle Triassic epoch (Anisian and Ladinian stages) of Italy, Slovenia, and Switzerland. [1] [2]
Perleidus is an extinct genus of ray-finned fish from the Triassic period. Fossils have been found in the Middle Triassic of Italy, Switzerland, and China. The inclusion of Early Triassic species in the genus Perleidus was questioned.
Watsonulus is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic epoch in what is now Madagascar. It may have also existed in what is now Himachal Pradesh, India, during the Induan age. The type species, described by Jean Piveteau, is Watsonia eugnathoides. Because "Watsonia" was preoccupied, the new genus name Watsonulus was later erected. The genus is named after David Meredith Seares Watson.
Brookvalia is an extinct genus of prehistoric freshwater ray-finned fish that lived during the Middle Triassic epoch.
Pteronisculus is an extinct genus of prehistoric ray-finned fish that lived during the Early Triassic and Middle Triassic epochs of the Triassic period worldwide.
Agecephalichthys is an extinct genus of prehistoric freshwater "palaeonisciform" ray-finned fish that lived during the Anisian age. It contains a single species, A. granulatus from the Hawkesbury Sandstone in what is now New South Wales, Australia.
Gracilignathichthys is an extinct genus of prehistoric ray-finned fish that lived during the early Ladinian stage of the Middle Triassic epoch in what is now Europe.
Luganoia is an extinct genus of prehistoric bony fish that lived during the Anisian and Ladinian ages of the Middle Triassic epoch. Fossils were recovered from the Besano Formation of Monte San Giorgio and Besano area and from the Zhuganpo Member of Guizhou, South China. It was also reported from the Ladinian of Spain.
Besania is an extinct genus of prehistoric marine ray-finned fish that lived during the Anisian and Ladinian ages of the Middle Triassic epoch in what is now southern/southeastern Switzerland and northern Italy. Fossils were recovered from the Besano Formation of Monte San Giorgio area and the Prosanto Formation of canton Graubünden, Switzerland.
Ctenognathichthys is an extinct genus of prehistoric marine ray-finned fish that lived during the Middle Triassic epoch of Europe, in the former Tethys Ocean.
Habroichthys is an extinct genus of prehistoric bony fish that lived during the early Ladinian stage of the Middle Triassic epoch, 242 to 232 million years ago. It has been found in Austria, China, Italy, Slovenia, and Switzerland. It was a small fish measuring 26 cm (10 in) long.
Peripeltopleurus is an extinct genus of prehistoric ray-finned fish that lived during the Anisian and Ladinian ages of the Middle Triassic epoch.
Cephaloxenus is an extinct genus of prehistoric marine ray-finned fish that lived during the early Ladinian stage of the Middle Triassic epoch.
Allolepidotus is an extinct genus of prehistoric marine neopterygian ray-finned fish from the Middle Triassic epoch of what is now Italy, Spain, and Switzerland. It was formerly referred to the halecomorph order Panxianichthyiformes, but is now thought to be a member of the Ionoscopiformes.
Bobasatrania is an extinct genus of prehistoric marine ray-finned fish that survived the Permian-Triassic extinction event. Fossils of Bobasatrania were found in beds of Changhsingian to Ladinian age. It was most speciose during the Early Triassic.
Dipteronotus is an extinct genus of stem-neopterygian ray-finned fish that existed during the Middle and Late Triassic epochs in what is now Europe and Morocco. As a typical feature, it had several ridge scales in front of its dorsal fin that created a spine-like structure.
Sargodon is an extinct genus of neopterygian ray-finned fish that lived during the Middle and Late Triassic epochs in what is now Europe.
Eoeugnathus is an extinct genus of prehistoric ray-finned fish belonging to the Halecomorphi. Eoeugnathus existed during the Middle Triassic in what is now Italy, Spain, and Switzerland. The type species is Eoeugnathus megalepis (monotypy).
Meridensia is an extinct genus of prehistoric ray-finned fish that lived during the Anisian and Ladinian ages of the Middle Triassic epoch in what is now southern Switzerland and northern Italy. Fossils were recovered from the Besano Formation of Monte San Giorgio and Besano area at the Swiss-Italian boundary.
Candelarialepis is an extinct genus of prehistoric marine ray-finned fish that lived during the Induan age of the Early Triassic epoch in what is now Nevada. It contains a single species, C. argentus. It was described from the Candelaria Formation.
Ardoreosomus is an extinct genus of marine ray-finned fish. It was described from the Induan aged Candelaria Formation of Nevada, United States, which was located near the equator during the Early Triassic epoch. It contains only one species, A. occidentalis (monotypy).
