Glyptolepis is an extinct genus of freshwater porolepiform lobe-finned fish which lived during Devonian Period, from the early Eifelian to the Givetian Age.
The following species are known:
The former species G. microlepidotus is now placed in its own genus, Gyroptychius, as is G. quebecensis, now placed in Quebecius.Glyptolepis is considered a stem lungfish, and its pectoral fins especially resemble those of the extant lungfish Neoceratodus.
G. groenlandica has a three-dimensionally preserved skull, for which the morphology of the braincase and the endocast is relatively well-known, among the best of any porolepiforms.
