Bathonian genera

Inoceramus (Greek: translation "fibrous shell" for the fibrous structure of the mineral crystals in the shell) is an extinct genus of fossil marine pteriomorphian bivalves that superficially resembled the related winged pearly oysters of the extant genus Pteria. They lived from the Early Jurassic to latest Cretaceous.

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).

Amphilestes is a genus of extinct eutriconodont mammal from the Middle Jurassic of the United Kingdom. It was one of the first Mesozoic mammals discovered and described.

Dearc ( ) is a genus of large-bodied rhamphorhynchine pterosaur from the Middle Jurassic Lealt Shale Formation of Scotland. The holotype, a juvenile or subadult that was still actively growing, has an estimated wingspan of 2.5 to 3 meters, making it the largest flying animal of its time. This pushes the origin of large pterosaurs back significantly, as it was previously assumed that pterosaurs did not reach greater body sizes until the short-tailed pterodactyloid lineages of the Cretaceous. The genus contains a single species, Dearc sgiathanach ( ).

Amphitherium is an extinct genus of stem cladotherian mammal that lived during the Middle Jurassic of England. It was one of the first Mesozoic mammals ever described. A recent phylogenetic study found it to be the sister taxon of Palaeoxonodon. It is found in the Forest Marble Formation and the Taynton Limestone Formation.

Phylloceras is an extinct genus of ammonoid cephalopods belonging to the family Phylloceratidae. These nektonic carnivores lived from Early Jurassic (Hettangian age) to Late Cretaceous (Maastrichtian age) (from 201.30 to 66.043 Ma).

Brachyphyllum (meaning "short leaf") is a form genus of fossil coniferous plant foliage. Plants of the genus have been variously assigned to several different conifer groups including Araucariaceae and Cheirolepidiaceae. They are known from around the globe from the Late Carboniferous to the Late Cretaceous periods.

Caturus (from , 'down' and 'tail') is an extinct genus of predatory marine fishes in the family Caturidae in the order Amiiformes, related to modern bowfin. It has been suggested that the genus is non-monophyletic with respect to other caturid genera.

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.

Lytoceras is an ammonite genus that was extant during most of the Jurassic and Cretaceous periods, and is the type genus for the family Lytoceratidae. These cephalopods were fast-moving nektonic carnivores.

genus of molluscs (fossil)

Henosferus is an extinct genus of australosphenidan mammal from Lower Jurassic of Argentina. The only recorded species, Henosferus molus, was found in the Cañadón Asfalto Formation of the Cañadón Asfalto Basin in Chubut Province, Patagonia.

Blapsium is an extinct genus of beetles from the Middle Jurassic of England. The only described species is B. egertoni, which was first described by John O. Westwood in 1854. The species is known from a single specimen found by the Earl of Enniskillen in the Stonesfield Slate, now known as part of the Taynton Limestone Formation, which Sir Philip Egerton then passed to Westwood for description. The specimen is deposited in the Natural History Museum, London. It is incompletely preserved, lacking a head, pronotum and legs. It has a broad, convex body. It has a very short metathorax, which sugge
