F.O.S.S.I.L. Technology

The ancient and highly advanced Fossilized Osteo-Skeletal Shield Integration Loadout Technology—or F.O.S.S.I.L. Technology for short—unleashes the primal power of the beasts. Sentient Fossilizer bots, infused with primordial energy, break apart and weaponize their allies.
Toys
War for Cybertron: Kingdom
Weapons under the Kingdom F.O.S.S.I.L. Technology have multiple 5 mm post hardpoints on them so that they can be combined in various configurations (some official), and can sometimes transform into different weapons. Some Deluxe Class figures are classified as "Deluxe Fossilizers", which can be disassembled into multiple weapons and armor to be used in the C.O.M.B.A.T. System. Undocumented in the instructions for the individual figures and entirely based on fan-made configurations of the Fossilizer toys; Paleotrex, Ractonite and Wingfinger can also combine to form an unnamed Fossilizer Combiner.

Notes

- Dracodon and Vertebreak may look like Fossilizers, but are not considered ones because they lack the ability to disassemble into gear for other figures. Of note, designer Mark Maher—when revealing Dracodon—referred to him as a Fossilizer.
- Hasbro PulseCon 2020's promotional poster for the Kingdom line features two unnamed Fossilizers (a Smilodon and a crocodilian of some kind) that served as concepts, but ultimately were not made into toys. The crocodilian is in beast mode, so it is unknown if they would have been a true Fossilizer or just a fossil-Transformer like Vertebreak and Dracodon.
- Like with previous lines, Kingdom also assigned code names, at least for the Fossilizers:
- Dracodon: "Autobot Fossil"
- Paleotrex: "Trex Bone"
- Ractonite: "Cat Bone"
- Vertebreak: "Decepticon Fossil"
- Wingfinger: "New Bone"
Foreign names
- Japanese: Fossilizer (フォッシライザー Fosshiraizā)
