Mazino eCastorocauda akasiyana munzira dzakawanda kubva kune mamwe madokodonts, zvichida nekuda kwekusiyana kwekudya (kunyangwe ona pazasi). Mazino akawanda emadhokodhonti akanga akagadzirirwa kudya zvinhu zvose. Mazino aCastorocauda anoratidza kuti mhuka yacho yaidya hove uye mhuka duku dzisina musana.
