Potanichthys

Extinct genus of fishes

Potanichthys is a fossil genus of thoracopterid fish found in deposits from China dating to the Ladinian age of the Middle Triassic epoch. The type species is P. xingyiensis, though P. wushaensis is considered as the alternative species name. It is known to have been the first vertebrate ever to have glided over water, and thus the first fish ever that had over-water gliding strategy. The genus name Potanichthys is a portmanteau of the Ancient Greek ποτάνος and ιχθύς. The species epithet refers to Xingyi city which is near the site where Potanichthys was discovered.
