Dino Buckler (ダイノバックラー, Dainobakkurā): Each Ranger wears a Dino Buckler which is a detachable silver buckle placed on each Zyuranger's waistband. The DynoBuckler is two-sided: the folded grip-side is out before the Zyurangers transformation, and the side showing the coin on which the figure of his/her own Guardian Beast is carved after. The Zyuranger transform by removing the Buckler from the belt and shouting "Dino Buckler!". Before the transformation, the DynoBuckler can be used in battle as a knuckle cover. The coin is the vital source of Zyurangers power; it stores Gaiatron (ガイアトロン, Gaiatoron) energy, a mysterious and perpetual power-source derived from mother nature. With its internal energy, the coin also has the power to heal a wounded person. While inside their Guardian Beasts, the Zyurangers can turn their coins into Dynocrystals which help in the transformation process of Daizyujin or Gouryuujin. Burai's Dyno Buckler was gold, and was called the Dragon Buckler. When Geki transforms into the Armed TyrannoRanger, his Buckler changes to gold as well.
