Scanilepis

Scanilepis is an extinct genus of prehistoric bony fish that lived during the Rhaetian-Hettangian stages (Late Triassic-Lower Jurassic boundary). The type species, S. dubia, is known from the Rhaetian freshwater deposits of the Bjuv member of the Höganäs Formation, southwestern Sweden.[3] A second species, S. spitzbergensis was described from the Hettangian of the Festning section of the Grøfjorden area in Spitsbergen, Norway.[4] This fish was originally identified as a member of the genus Gyrolepis, as Gyrolepis dubius, being latter assigned to its own genus and classified as a member of Palaeonisciformes.[4] Latter works placed it as a taxon close to the origin of the family Amiidae, until was found latter to belong to its own family (Scanilepididae) and order, Scanilepiformes.[5] Regarding to the microstructure of its scales, Scanilepis approaches the condition of Polypterus or Erpetoichthys more than any other genera.[6]
