Pteraspidomorpha (also frequently spelled Pteraspidomorphi) is an extinct class of early jawless fish. They have long been regarded as closely related or even ancestral to jawed vertebrates, but the few characteristics they share with the latter are now considered as basal traits for all vertebrates.
