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.23 Potential indeterminate records stretch as far back as the early Carboniferous.4
Taxonomy
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
