Toarcian 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.

Siderops (from the Greek sideros meaning “iron” and -ops meaning “face” ) is an extinct genus of chigutisaurid temnospondyl from Early Jurassic of Australia, containing the species S. kehli (named after the Kehl family of ‘Kolane’, Wandoan, Queensland where the fossil was found).

Bishanopliosaurus is a genus of plesiosaur. The type species is B. youngi, based on remains found in the Ziliujing Formation of China.

Microcleidus is an extinct genus of sauropterygian reptile belonging to the Plesiosauroidea. The species has 40 neck vertebrae and a short tail of 28 vertebrae. Fossils of the genus have been found in France, the Posidonia Shale in Germany and Luxembourg, and the Alum Shale Formation of England.

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.

genus of plants (fossil)

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.

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).

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.

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.

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.

Plesionectes (meaning "near swimmer") is an extinct genus of basal plesiosauroid plesiosaurs known from the Early Jurassic (Toarcian age) Posidonia Shale of Germany. The genus contains a single species, Plesionectes longicollum, known from a well-preserved, nearly complete skeleton.

genus of molluscs (fossil)

Melkamter () (meaning "winged lizard") is an extinct genus of monofenestratan pterosaurs from the Early Jurassic Cañadón Asfalto Formation of Argentina. The genus contains a single species, M. pateko, known from a partial skull and fragmentary postcranium. Melkamter represents the oldest known monofenestratan pterosaur in the fossil record.
