Aspidorhynchus (from Ancient Greek ἀσπίς (aspís), meaning "shield", and ῥύγχος (rhúnkos), meaning "snout") is an extinct genus of predatory ray-finned fish from the Middle Jurassic to the earliest Cretaceous. Fossils have been found in Europe, Antarctica and the Caribbean.

Callipurbeckia is an extinct genus of marine semionotiform ray-finned fish from the Late Jurassic and Early Cretaceous periods. Fossils have been found in Germany, Tanzania, and England.

Peramus is an extinct genus of cladotherian mammal. It lived in the Late Jurassic and Early Cretaceous of Europe and North Africa.

Amblotherium is an extinct genus of Late Jurassic and Early Cretaceous mammal. The type species Amblotherium pusillum is from the Lulworth Formation of southern England, while the referred species Amblotherium gracile is from stratigraphic zones 2, 3 and 5 of the Morrison Formation of the US.

Trioracodon is an extinct genus of Late Jurassic to Early Cretaceous eutriconodont mammal found in North America and the British Isles. It was named in 1928.

Pleurosternon is an extinct genus of freshwater pleurosternid turtle from the latest Jurassic to earliest Cretaceous of Europe. Its type species, P. bullockii, was described by the paleontologist Richard Owen (noted for coining the word Dinosauria) in 1853. Since then, and throughout the late 19th century, many fossil turtles were incorrectly assigned to this genus, though only two are currently considered valid.

Isanichthys is an extinct genus of freshwater lepidotid ginglymodian fish from the Late Jurassic and Early Cretaceous. Four species are known from Thailand, China and the United Kingdom, two of which were previously classified in genera.
