Pteronisculus is an extinct genus of prehistoric bony fish that lived during the Early Triassic and Middle Triassic epochs of the Triassic period. The preoccupied genus name "Glaucolepis" Stensiö, 1921 (non Glaucolepis Braun, 1917) is a synonym of Pteronisculus White, 1933.[3]
Pteronisculus was originally referred to the family Palaeoniscidae, but was removed due to differences to Palaeoniscum.[4] Based on similarities with Turseodus it was provisionally included in .[5] A synapomorphy of Pteronisculus and Turseodus is the tooth-bearing lachrymal.
Pteronisculus had a wide geographic range during the Early Triassic.[1] Fossils were collected in Greenland, Madagascar, Spitsbergen and the United States (possibly also British Columbia). From the Middle Triassic, it is only known from South China.[5][4] Its occurrence in the Permian of South Africa has been questioned. About 12 species have been described to date, ranging from 11 centimetres (0.36 ft) to 40 centimetres (1.3 ft) in length.
