Elonichthys is an extinct genus of prehistoric freshwater ray-finned fish known from the late Paleozoic.[1] [2] The genus sensu stricto contains three species known from the latest Carboniferous to the earliest Permian of freshwater ecosystems of Europe, but as a former wastebasket taxon, it contains many more dubiously-classified species from the Carboniferous and Permian of Europe, Greenland, South Africa, and North America.[2] [3]
Species
[edit ]The following are species within Elonichthys sensu stricto:[2] [3] [4]
- †E. germari Giebel, 1848 (type species) - Late Carboniferous (Gzhelian) of Germany (Siebigerode Formation)
- †E. fritschi Friedrich, 1878 - Early Permian (Asselian) of Germany (Meisenheim Formation)
- †E. krejcii (Fritsch, 1895) - Gzhelian of the Czech Republic (Slaný Formation)
Former species
[edit ]The following are more dubious species that were formerly classified into this genus. However, the majority have been found to no longer even be members of Elonichthyidae.[2] [3] [4]
- †E. aitkeni Traquair, 1886 - Carboniferous of England (Culm Measures and Lancashire Coalfield) → Mesonichthys aitkeni (Traquair, 1886)
- †E. caudalis Traquair, 1877 - Middle Carboniferous (Moscovian) of England (Lancashire Coalfield) → not an elonichthyid
- †E. egertoni (Egerton, 1850) - Middle Carboniferous (Bashkirian to Moscovian) of England (Lancashire Coalfield) → not an elonichthyid
- †E. gigas Fritsch, 1877 → Acrolepis gigas (Fritsch, 1877)
- †E. macropterus (Bronn, 1829) → Rhabdolepis macropterus (Bronn, 1829)
- †E. peltigerus Newberry, 1856 - Moscovian of Illinois and Ohio, United States (Carbondale Formation and Francis Creek Shale) → not an elonichthyid. A well-known, numerous species in the Mazon Creek fossil beds.[5] [6]
- †E. portlocki (Egerton, 1850) - Tournaisian to Visean of England, including Northern Ireland (Tyrone Group, Pendleside Limestones) → potentially an indeterminate elonichthyid
- †E. pulcherrimus Traquair, 1881 - Early Carboniferous (Visean) of Scotland (Glencartholm Volcanic Beds, Leitrim Group) → not an elonichthyid
- †E. robisoni (Hibbert, 1835) (=E. bucklandi (Agassiz, 1835)) - Visean of Scotland (Strathclyde Group) → not an elonichthyid, most likely a kentuckiid
- †E. serratus Traquair, 1881 - Visean of Scotland (Glencartholm Volcanic Beds, Leitrim Group) → not an elonichthyid, most likely a palaeoniscid
- †E. semistriatus Traquair, 1877 → Moscovian of England (Lancashire Coalfield) → not an elonichthyid
- †E. striatus (Agassiz, 1835) → Cosmoptychius striatus (Agassiz, 1835)
The following other dubious species are also known:
- Elonichthys disjunctus
- Elonichthys hypsilepus
- Elonichthys perpennatus
- Elonichthys punctatus
- Elonichthys whaitsi
