The [type species](/source/type_species), '''''S. dubia''''', is known from the Rhaetian freshwater deposits of the Bjuv member of the [Höganäs Formation](/source/H%C3%B6gan%C3%A4s_Formation), southwestern [Sweden](/source/Sweden).{{cite journal |last1=Lehman |first1=J.-P. |author-link=Jean-Pierre Lehman |title=Le genre ''Scanilepis'' Aldinger du Rhétien de la Scanie (Suède) |journal=Bulletin of the Geological Institutions of the University of Uppsala |date=1980 |volume=8 |issue=1 |pages=113–133 |lang=fr |url=https://paleoarchive.com/literature/Lehman1979-ScanilepisRhetienScanie.pdf|access-date=12 December 2021}} A second species, ''S. spitzbergensis'' was mentioned from the Hettangian of the [Festning section](/source/Festning_section) of the [Grøfjorden](/source/Gr%C3%B8fjorden) area in [Spitsbergen](/source/Spitsbergen), Norway{{cite journal |last=Aldinger |first=H. |year=1935 |title=Das Alter der jungpaläozoischen Posidonomyaschiefer von Ostgrönland |journal=Meddelelser om Grønland |volume=98 |pages=1–24 |lang=de}}{{cite journal |last1=Aldinger |first1=H. |title=Permische Ganoidfisch aus Ostgrönland |journal=Meddelelser om Grønland |date=1937 |volume=102 |issue=2 |pages=1–392 |lang=de}} but was never described. ==Description== The original material of this genus, described by Aldinger in 1937, was destroyed during WW2 in Germany. Latter, new material was recovered from Bjuv locality, including skull and postcraneal material. This taxon represents a relatively large fish, up to 110 cm, with an isolated isolated caudal suggesting a fish of at least 2 m. The head presents unusual relative small eyes and a correlative maxilla with very large posterior plate and bony craneal top. This taxon presents a relatively elongated bodyplan with an odd dorsal fin, exceptionally long, beginning behind the head and reaching the caudal. Pectoral fins weren't found, and are assumed to be small and only played a reduced role. ==Classification== This fish was originally identified as a member of the genus ''[Gyrolepis](/source/Gyrolepis)'', as ''Gyrolepis dubius'', but was later assigned to its own genus (''Scanilepis'') and [family](/source/Family_(taxonomy)) ([Scanilepididae](/source/Scanilepididae)), and classified as a member of [Palaeonisciformes](/source/Palaeonisciformes). Later works placed it as a [taxon](/source/taxon) close to the origin of the family [Amiidae](/source/Amiidae), until it was found later to belong to its own [order](/source/order_(biology)), [Scanilepiformes](/source/Scanilepiformes), closely related with the genus ''[Evenkia](/source/Evenkia_(fish))''.{{cite book |last1=Sytchevskaya |first1=E.
