- "Spiraling round and round, Gurumonite!"
- ―ED theme lyric[src]
Gurumonite is a emerald green Ammonite that was modified to fight the Deboth Army. Along with the other twelve Guardians, Gurumonite's body was destroyed by the Great Land Devil Gadoma 65 million years ago; while its physical form was reduced to a Secret Stone, its Kyoryu Spirit is held within the Zyudenchi.
- 20. Gurumonite (フタバイン): 3 emerald green Zyudenchi (originally 1) holding the Kyoryu Spirit of the Ammonite. When used in a Gaburivolver, it makes anyone it hits become dizzy to the point of passing out once a Kyoryuger spins their finger in a spiral pattern.

- Kyoryu Black (Brave 34-35)

Behind the scenes
All of the Zyudenryu/Zyudenchi sport a name that is a portmanteau between their effect/motif and their respective animal name, Gurumonite is a portmanteau of Ammonite and Guruguru (the Japanese onomatopoeiac word for "spinning").
- Though remaining unseen both on-screen and in the Kyoryuger toyline, a mecha form of Gurumonite appears in the form of the Ammonite Zord from the Power Rangers Dino Charge toyline.
