The major strength of the fruit as rumored is the ability to mineralize instantly anything non living, similarly to the Mero Mero no Mi, but it only works to already dead organic tissue and won't affect anything non organic or still alive. Any fossilized organic tissue can be reverted back to it's original state just before death, allowing the user of this fruit to bestow any Fossil to it's original state but albeit still dead. Any fossil the user touches with his right hand can be tampered with and controlled as if it's a marionette as long as the user maintains physical contact, while his left hand allows for him to remotely draw close to him fossils, probably a quirk and not set in stone thou.
