Dino Buckler (ダイノバックラー Daino Bakkurā): Each Ranger wears a Dino Buckler which is a detachable silver buckle placed on each Zyuranger's waistband. The Dino Buckler 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 Dino Buckler can be used in battle as a knuckle cover for added attack strength. The coin is the vital source of the 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, although its ability to heal mortal wounds is seemingly limited. While inside their Guardian Beasts, the Zyurangers can turn their coins into Dinocrystals which help in the transformation process of Daizyujin or Gouryuujin. Burai's Dino Buckler was gold, and was called the Dragon Buckler (ドラゴンバックラー Doragon Bakkurā). When Geki transforms into the Armed TyrannoRanger, his Buckler changes to gold as well.
The sequence was redone from scratch for Kyoryuger vs. Go-Busters, taking inspiration from Adam Park's Once a Ranger morph (with the difference that the suit forming effect is a magma explosion coming out from the Dinobuckler and then returning to Geki's body to form the suit rather than being formed by rocks breaking to reveal the suit like in Adam's Once a Ranger morph):
- In Mighty Morphin Power Rangers, actual toy replicas of the Dino Bucklers were used to represent the Rangers' Power Morphers. Using Super Sentai toys as props became a tradition in the Power Rangers franchise for years to come.
- Burai's golden Dragon Buckler shares the same design as the standard silver Dino Buckler. As such, the strip of color featured on the buckler's backside features the standard 5 Zyuranger colors, but no green indicator.
- In a twist of irony, the Dino Bucklers used in the Kyoryuger vs. Go-Busters movies were actually Legacy Morpher toys from Bandai's Power Rangers Legacy line.
