Beishanichthys is an extinct genus of freshwater ray-finned fish which existed in Gansu Province, China during the Olenekian age of the early Triassic period. It contains a single species, B. brevicaudalis, first named by Guang-Hui Xu, Ke-Qin Gao in 2011 based on fossils from the Lower Triassic lake deposits exposed in Beishan area. [1] [2] It is considered a scanilepiform, a group of early cladistians related to the modern bichirs, although Beishanichthys was not incorporated into the analyses that found this phylogenetic placement among the cladistians.

<span class="mw-page-title-main">Thoracopteridae</span> Extinct family of ray-finned fishes

Thoracopteridae is an extinct family of prehistoric bony fish; classified with the order Peltopleuriformes. This lineage of Triassic flying fish-like Perleidiformes converted their pectoral and pelvic fins into broad wings very similar to those of their modern counterparts. However, this group is not related to modern flying fish from the family Exocoetidae, instead being a case of convergent evolution.

<i>Amia</i> (fish) Genus of ray-finned fishes

Amia, commonly called bowfin, is a genus of bony fish related to gars in the infraclass Holostei. They are regarded as taxonomic relicts, being the sole surviving species of the order Amiiformes, which dates from the Jurassic to the Eocene, persisting to the present. There are two living species in Amia, Amia calva and Amia ocellicauda, and a number of extinct species which have been described from the fossil record.

The Zhuganpo Formation is a Triassic geologic unit found in southern China. It has historically been known as the Zhuganpo Member of the Falang Formation. A diverse fossil assemblage known as the Xingyi biota or Xingyi Fauna can be found in the upper part of the Zhuganpo Formation. Fossils of the Xingyi biota include articulated skeletons of marine reptiles, abundant fish, and a plentiful assortment of invertebrates indicating a Ladinian to Carnian age for the sediments of the formation.

<span class="mw-page-title-main">Redfieldiiformes</span> Extinct order of ray-finned fishes

Redfieldiiformes is an extinct order of ray-finned fish (actinopterygians) which lived from the Middle Triassic to Early Jurassic. Redfieldiiforms were fairly typical Triassic fish in overall anatomy. They had a fusiform body shape with thick, ganoine-covered scales. The dorsal and anal fins were large, positioned opposite from each other, and shifted back, close to the tail. The caudal fin was hemiheterocercal, with the vertebral column and body scales extending into an upper lobe which was equal in size and shape to the lower lobe. They also had several characteristic skeletal traits, such as a hatchet-shaped preopercle, a series of fulcra fringing the fins, a reduced number of branchiostegal rays, and a snout ornamented with tubercles.

<i>Robustichthys</i> Extinct arthropod genus

Robustichthys is an extinct genus of ray-finned fish from the Middle Triassic period, contains only one species R. luopingensis. It belonged to the clade Halecomorphi, which were once diverse during the Mesozoic Era, but which are today represented by only a single species, the bowfin. Halecomorphs are holosteans, a clade which first appeared in the fossil record during the Triassic.
