A Fossil is a naturally-generated, underground structure implemented in The Frostburn Update.


Fossils can be found buried underground on rare occasions in desert and Swamp Biomes. They are composed of several Bone Blocks arranged in the shape of a giant spinal column, rib cage, or skull. Some of the bone blocks may be replaced by coal. The fossil structure is not known by many players, this is most likely due to the fact that not many players mine in deserts or swamps. The fossil is a good source of bones for players who like to play on peaceful. The fossil does not depend on the Y level as it can generate at any Y level as long as it is underground.
