Jurassic bony fish

Leptolepis (from , 'slight' and 'scale') is an extinct genus of stem-teleost fish that lived in what is now Europe (Germany, Luxembourg, France, England, Italy and maybe Greece) and North of Africa (Algeria, Tunisia and Morocco) during the Jurassic period (Pliensbachian–Callovian ages).

Coelacanthidae is an extinct family of coelacanths found in freshwater and marine strata throughout the world, originating during the Permian, and finally dying out during the Jurassic.

Mawsoniidae is an extinct family of prehistoric coelacanth fishes which lived during the Triassic to Cretaceous periods. Members of the family are distinguished from their sister group, the Latimeriidae (which contains the living coelacanths of the genus Latimeria) by the presence of ossified ribs, a coarse rugose texture on the dermatocranium and cheek bones, the absence of the suboperculum and the spiracular, and reduction or loss of the descending process of the supratemporal.

Gyrodus (from , 'curved' and 'tooth') is an extinct genus of pycnodontiform ray-finned fish that lived from the Middle Jurassic (Bajocian) to the Early Cretaceous (Barremian).

Dapedium (from , 'pavement') is an genus of deep-bodied ray-finned fish belonging to the extinct family Dapediidae. Dapedium lived in the Late Triassic to the Middle Jurassic period, from the late Norian to the early Aalenian, being one of the most abundant fossil fish found in Early Jurassic deposits in Europe.

Hypsocormus (from , 'height' and 'timber log') is an extinct genus of pachycormid fish from the Middle to Late Jurassic of Europe. Fossils have been found in Germany, France and the UK.

Libys is a genus of coelacanth fish in the family of Latimeriidae. Species of Libys lived during the Lower-Upper Jurassic period (Toarcian - Tithonian, about 183 to 145 million years ago).

Euthynotus is an extinct genus of prehistoric marine ray-finned fish that lived in Europe during the Early Jurassic epoch. It is generally considered the basalmost pachycormiform, although more recent studies instead place it as the most basal member of the predatory lineage within the pachycormiforms, the Protosphyraenidae.

Ferganoceratodus (from Fergana + Ceratodus) is a genus of prehistoric freshwater lungfish known from worldwide during the Mesozoic. Based on morphological evidence, it has either been recovered as a basal member of the Ceratodontiformes or to be the sister group of the Neoceratodontidae (containing the extant Australian lungfish).

Holophagus is an extinct genus of coelacanth belonging to Latimeriidae. The type species, Holophagus gulo, is known from the Lower Jurassic marine Lias of England. Some authors have considered the genus restricted to the Lias of England.

Chondrosteus ("cartilage bone" in Greek) is a genus of extinct marine actinopterygian (ray-finned fish) belonging to the family Chondrosteidae. It lived during the Hettangian and Sinemurian (early Early Jurassic) in what is now England. Chondrosteus is related to sturgeons and paddlefishes as part of the clade Acipenseriformes, and is one of the earliest known definitive members of the group. Similar to sturgeons, the jaws of Chondrosteus were free from the rest of the skull (projectile jaw system). Its scale cover was reduced to the upper lobe of the caudal fin like in paddlefish. It is repre

Mesturus is an extinct genus of ray-finned fish from the Jurassic.

Macrosemius is an extinct genus of macrosemiid fish known from the Late Jurassic of Germany.

Ophiopsis is an extinct genus of prehistoric ray-finned fish belonging to the family Ophiopsidae. Specimens are known from the Tithonian-age Solnhofen Formation of Bavaria, Germany.

Ophiopsiella is an extinct genus of prehistoric ray-finned fish.

Histionotus is an extinct genus of prehistoric ray-finned fish.

Heterolepidotus is an extinct genus of prehistoric ray-finned fish.

Arganodus is an extinct genus of freshwater lungfish that had a wide global distribution throughout much of the Triassic period, with a single species surviving across Gondwana into the Cretaceous. It is the only member of the family Arganodontidae, although it is sometimes placed in the Ceratodontidae or synonymized with the genus Asiatoceratodus.

Gyrosteus is an extinct genus of a large ray-finned fish belonging to the family Chondrosteidae. It comprises the type species, Gyrosteus mirabilis, which lived during the early Toarcian (Late Early Jurassic) in what is now northern Europe. A possible second species, "Gyrosteus" subdeltoideus, is known from otoliths.

Ionoscopus is an extinct genus of ray-finned fish.

Pachythrissops is an extinct genus of ray-finned fish. It contains two species, P. laevis from the Purbeckian of England and P. propterus from the Tithonian of Germany. A third species, P. vectensis, has been reassigned to the elopiform genus Arratiaelops. Pachythrissops is often regarded as one of the most primitive members of the order Ichthyodectiformes; however, a phylogenetic analysis by Cavin et al. (2013) placed it and the related genus Ascalabothrissops outside the group.

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.

Lycopteridae is an extinct family of freshwater osteoglossomorph ray-finned fishes.
