Scanilepis
Scanilepis is an extinct genus of prehistoric bony fish that lived during the Rhaetian-?Hettangian ages (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.[4] A second species, S. spitzbergensis was mentioned from the Hettangian of the Festning section of the Grøfjorden area in Spitsbergen, Norway[5][6] but was never described.[2]

Classification
This fish was originally identified as a member of the genus Gyrolepis, as Gyrolepis dubius, but was later assigned to its own genus (Scanilepis) and family (Scanilepididae),[5] and classified as a member of Palaeonisciformes.[6] Later works placed it as a taxon close to the origin of the family Amiidae, until it was found later to belong to its own order, Scanilepiformes.[7] Regarding to the microstructure of its scales, Scanilepis approaches the condition of Polypterus or Erpetoichthys more than any other genera.[8]
