Amblypterus (from Greek: ἀμβλύς amblys, 'blunt' and Greek: πτερόν pteron 'wing' or 'fin')[1] is an extinct genus of freshwater ray-finned fish that lived during the Gzhelian (upper Carboniferous) and Cisuralian (lower Permian) epoch in what is now Europe (France & Germany) and possibly India, the United States and Argentina.[2][3] Potential indeterminate records stretch as far back as the early Carboniferous.[4]
Taxonomy
[edit]This genus displays close similarities to Paramblypterus, to the extent that both may be synonymous, although presently they are considered distinct. The type specimen of A. latus is lost.[5]
Species
[edit]The following species are known:[4][6]
- A. arcuatus Egerton, 1850 - Early Permian (Sakmarian) of Germany (Goldlauterer Formation)
- A. baylei Sauvage, 1890 - - Early Permian (Asselian) of France (Muse Formation)
- A. beaumonti Egerton, 1850 - Asselian of France (Muse Formation)
- A. berthieri Sauvage, 1893 - Asselian of France (Assise de Millery Formation)
- A. bibractensis Sauvage, 1893 - Asselian of France (Assise de Millery Formation)
- A. decorus Egerton, 1850 - Late Carboniferous (Gzhelian) of France (Commentry Shales)
- A. kashmiriensis Woodward & Seward, 1905 - Early Permian (Artinskian) of Jammu & Kashmir, India (Mamal Formation)
- A. latus Agassiz, 1833 (type species) - Asselian of Germany (Meisenheim & Lebacher Schichten Formations)[7]
- A. magnus Sauvage, 1890 - Asselian of France (Muse Formation)
- A. stewarti Romer, 1942 - Late Carboniferous (Kasimovian to Gzhelian) of West Virginia, US (Uniontown Limestone)[8]
- A. symmetricus Woodward, 1905 - Artinskian of Jammu & Kashmir, India (Mamal Formation)
- A. traquairi Woodward, 1891 - Asselian of Germany (Meisenheim & Lebacher Schichten Formations)[6]
