Ladinian genus extinctions

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).

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

Bobasatrania is an extinct genus of prehistoric marine ray-finned fish that survived the Permian-Triassic extinction event. Fossils of Bobasatrania were found in beds of Changhsingian (late Permian) to Ladinian (Middle Triassic) age. It was most speciose during the Early Triassic.

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
