Glyptolepis leptopterus Agassiz in National Museum of Ireland - Natural History

Glyptolepis is an extinct genus of porolepiform lobe-finned fish which lived during Devonian Period, from the early Eifelian to Frasnian Age.^[1]^[2]^[3] Species include Glyptolepis baltica, Glyptolepis groenlandica, and Glyptolepis leptopterus.^[4]^[5]

Glyptolepis is considered a stem lungfish, and its pectoral fins especially resemble those of the extant lungfish Neoceratodus.^[4]
