The unique enchantments that Fossils and Archeology Revival adds, Archeology and Paleontology, can only be used on pickaxes or books. They are both randomly suggested by the enchantment table, with enchantments that are of equal or lesser cost than the amount of levels the player has becoming available. The greater amount of levels the player has, the higher the chance of getting a higher-level enchantment is. The two enchantments were removed in the 8.0.0 update.
