Fossil
Fossils are a special type of currency that can be socketed into resonators to modify the crafting behavior in specific ways, released in the Delve league.
Fossils belong to the Stackable Currency item class for use in Item Filters[1].

Shift click to unstack., using a resonator on an item with a metamod (such as prefixes cannot be changed or cannot roll caster mods) will completely ignore the effects of the modifier.
