Gnathostomata

Qianodus tooth whorls from late Aeronian strata at approximately 439 Ma anchor the 439–0 Ma Gnathostomata route; isolated dental elements provide a minimum sampled occurrence, not the origin of jaws, crown age or global FAD. This navigation entry is not a phylogeny or a complete taxon dossier.
