Gnathostomata (; from Ancient Greek: γνάθος (gnathos) 'jaw' + στόμα (stoma) 'mouth') are jawed vertebrates. Gnathostome diversity comprises roughly 60,000 species, which accounts for 99% of all extant vertebrates, including all living bony fishes (both ray-finned and lobe-finned, including the terrestrial tetrapods) and cartilaginous fishes, as well as extinct prehistoric fish such as placoderms and acanthodians.
