Prehistoric fish of Europe

Helicoprion is an extinct genus of large shark-like cartilaginous fish that lived from the Early to the Middle Permian, about 290-270 million years ago. Helicoprion is a member of the Eugeneodontiformes, an extinct order of cartilaginous fish within the clade Holocephali, a group today represented only by chimaeras. It is also the type genus of the Helicoprionidae, a family of eugeneodonts characterised by distinctive tooth structures called tooth whorls. Helicoprion was first named in 1899 by Alexander Karpinsky on the basis of fossils discovered in Russia and Australia, the generic name mean

Hybodus (from , 'crooked' and 'tooth') is an extinct genus of hybodont. Numerous species have been assigned to Hybodus spanning a large period of time, and it is currently considered a wastebasket taxon that is 'broadly polyphyletic' and requires reexamination. It has been suggested that Hybodus sensu stricto only consists of two species, the type species H. reticulatus and H. hauffianus, both known from the Early Jurassic of Europe, with H. obtusus from the Middle-Late Jurassic of Europe possibly also being a true species of Hybodus.

Thelodus (from , 'nipple' and , 'tooth') is an extinct genus of thelodont agnathan that lived during the Silurian period. Fossils have been found in Europe, Asia and North America.

Ischyodus (from , 'power' and 'tooth') is an extinct genus of chimaera. It is the most diverse and long-lived chimaera genus, with over 39 species found worldwide spanning over 140 million years from the Middle Jurassic to the Miocene. Almost all species are only known from tooth plates, with the exception of the Jurassic species I. quenstedti. Complete specimens of I. quenstedti from the Late Jurassic of Germany most closely resemble the genus Callorhinchus amongst living chimaera genera. It is sometimes placed in the "Edaphodontidae", a unclearly defined group of chimaera with an uncertain p

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

Acrodus (from , 'high' and 'tooth') is an extinct genus of hybodont spanning from the Early Triassic to the Late Jurassic. (The Early Cretaceous species "Acrodus" nitidus affinity to the genus is questionable.) It was durophagous, with blunt, broad teeth designed for crushing and grinding. Some Middle Triassic species have been suggested to have grown to lengths of . Species are known from both marine and freshwater environments, with all Middle and Late Jurassic species only known from freshwater.

Striatolamia is an extinct genus of sharks belonging to the family Odontaspididae. These extinct sharks lived from the Early Paleocene to Late Miocene (61.7 to 10.3 Ma).
