Species

Y. macrocephalus

Yelangichthys is an extinct genus of prehistoric bony fish that lived during the Anisian age of the Middle Triassic epoch in what is now Guizhou, China. [2] The type and only species, Y. macrocephalus, is known from two specimens, both of which were recovered from the Upper Member of the Guanling Formation. [2]

Ecology & evolution

Phylogenetic analysis places Yelangichthys as a basal member of the Saurichthyiformes. It is distinguished from other saurichthyiforms most notably by its broad skull and crushing dentition. Similarities with other saurichthyiforms include the lengthened rostrum. It is referred to its own monotypyic family, Yelangichthyidae. [2]

<i>Saurichthys</i> Extinct genus of fishes

Saurichthys is an extinct genus of predatory ray-finned fish from the Triassic Period. It is the type genus of the family Saurichthyidae, and the most speciose and longest lasting genus in the family. This family also includes the Permian Eosaurichthys (China) and the Jurassic Saurorhynchus from Europe and North America, though it may be more appropriate to treat these as subgenera of Saurichthys, due to the genus Saurichthys otherwise being paraphyletic.
