The following species are currently classified in the genus. Many were formerly classified in Ptychoceratodus, Ceratodus, or other genera, but were reassigned to this genus in 2023:[4][3][5]
- †F. acutus (Priem, 1924) - Late Triassic of Madagascar (=Ptychoceratodus acutus)
- †F. annekempae Cavin, Deesri & Chanthasit, 2020 - Phu Kradung Formation, Thailand, Late Jurassic (named after Anne Kemp)[3][6]
- †F. concinnus (Meyer & Plieninger, 1844) - Late Triassic (Carnian to Norian) of Germany (Weser Formation)
- †F. cuyanus (Agnolin et al, 2017) - Late Triassic of Argentina (=Ptychoceratodus cuyanus)
- †F. edwardsi Challands et al., 2023 - Late Triassic (Norian) of Zimbabwe (Pebbly Arkose Formation)[3]
- †F. hislopianus (Oldham, 1859) - Late Triassic of India (Maleri Formation)
- †F. iheringi (Ameghino, 1906) - Late (Cenomanian) Cretaceous of Argentina (Amarilla Formation)
- †F. jurassicus Nessov & Kaznyshkin, 1985 (type species) - Middle Jurassic of Kyrgyzstan (Balabansai Formation)
- †F. madagascarensis (Martin, 1982) - Late Cretaceous (Coniacian) of Madagascar (Ankazomihaboka Formation)
- †F. martini Cavin et al., 2007 - Phu Kradung Formation, Thailand, Late Jurassic-?earliest Cretaceous
- ?†F. patagonicus (Agnolin, 2010) - Campanian/Maastrichtian of Argentina (=Atlantoceratodus patagonicus)
- †F. phillipsi (Agassiz, 1838) - Middle Jurassic of England (Taynton Limestone), Late Triassic (Carnian) of Germany, potentially Carnian of Brazil, Early Triassic of South Africa, early Triassic of Australia
- †F. rectangulus (Linck, 1936) - Late Triassic (Norian) of Greenland (Fleming Fjord Formation) and Germany (Löwenstein Formation)[7] (=Ptychoceratodus rectangulus (Linck, 1936))
- †F. roemeri (Skrzycki, 2015) - Late Triassic (Carnian) of Poland (Grabowa Formation)
- †F. szechuanensis (Young, 1942) - Thailand (Huai Hin Lat Formation) Late Triassic (Norian) South China, Jurassic, Khlong Min Formation, Thailand, Middle Jurassic, Phu Kradung Formation, Thailand, Late Jurassic-?earliest Cretaceous
Potential remains have also been reported from the late Early Cretaceous (Albian) of Tunisia, the Triassic of Germany, and the Late Cretaceous of Madagascar.[8]
Unusually, North America is the only continent to lack any records of Ferganoceratodus, despite the extremely wide geographic and stratigraphic range of the genus. It has been suggested that some of the potential "Ceratodus" species from North America may be members of Ferganoceratodus, or that Ferganoceratodus was excluded from North America by the similar but highly distinct Potamoceratodus lineage.[3]
