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]
