Anisian genus first appearances

Lariosaurus is an extinct genus of nothosaurid from the Middle Triassic (late Anisian to late Ladinian stage) of central and western Europe and China. With a complete specimen of L. xingyiensis measuring long and L. hongguoensis possibly measuring up to long, it was one of the smallest known nothosaurs. First discovered at Perledo on the Lake Como in 1830, it was named in 1847 by Curioni, its name meaning "Lizard from Larius", the ancient name of the lake. This makes it one of the earliest studied reptiles from the Alps. It is known from an almost complete skeleton holotype and several other f

Ticinosuchus is an extinct genus of suchian archosaur (distantly related to modern crocodilians) from the Middle Triassic (Anisian–Ladinian) of Switzerland and Italy. The genus name means "Ticino crocodile" due to its origin from the Swiss canton Ticino. It is one of the only terrestrial animals found in the Besano Formation, a fossil-rich lagerstätte on Monte San Giorgio renowned for its marine fauna (including different groups of fossil fishes, ichthyosaurs, tanystropheids, nothosaurs and placodonts, among others).

Qianosuchus is an extinct genus of aquatic poposauroid archosaur from the middle Triassic (Anisian) Guanling Formation of Pan County, China. It is represented by two nearly complete skeletons and a crushed skull preserved in the limestone. Qianosuchus was at least 3 metres long, and had several skeletal adaptations which indicate a semi-marine lifestyle, similar to modern-day saltwater crocodiles. These adaptations have not been seen in any other archosaur from the Triassic.

Macrocnemus is an extinct genus of archosauromorph reptile known from the Middle Triassic (Late Anisian to Ladinian) of Europe and China. Macrocnemus is a member of the Tanystropheidae family and includes three species. Macrocnemus bassanii, the first species to be named and described, is known from the Besano Formation and adjacent paleontological sites in the Italian and Swiss Alps. Macrocnemus fuyuanensis, on the other hand, is known from the Zhuganpo Formation in southern China. A third species, Macrocnemus obristi, is known from the Prosanto Formation of Switzerland and is characterized b

Yuanansuchus is an extinct genus of mastodonsauroid temnospondyl. Fossils have been found from the Xinlingzhen formation in Yuan'an County, Hubei, China and date back to the Anisian stage of the Middle Triassic.

Gyrolepis is an extinct genus of prehistoric ray-finned fish from the Middle-Late Triassic epochs in what is now Europe. It is known both from complete specimens and isolated skeletal elements, such as scales or teeth. thumb|left|Isolated teeth and scales ascribed to Gyrolepis

Xinminosaurus is an extinct genus of cymbospondylid ichthyosaur known from the Middle Triassic (mid-late Anisian stage) of Guizhou Province, China.

Habroichthys is an extinct genus of peltopleuriform ray-finned fish from the Middle Triassic, and is the only genus of the monotypic family Habroichthyidae. Fossils of the fish have been found in a number of countries being Slovenia, Italy, and China. Species within the genus were small with the largest species having a standard length of only . Due to their small size, the preservation of the skull bones of the fish are usually poorly preserved, resulting in species being identified by the number of flank scales along with the placement of certain fins on the body. Within their environment, H
