Dyrosauridae on sukupuuttoon kuollut krokotiilimaisten arkosaurien heimo, joka eli myöhäiseltä liitukaudelta eoseenille. Heimon jäsenet muistuttivat ulkoisesti nykyisiä gaviaaleja pitkine, kapeine, hampaikkaine kuonoineen. Ne olivat vahvoja uimareita, jotka saalistivat kalaa matalissa rannikkovesissä ja murtovetisissä joensuissa.[1]
