Uses[edit | edit source]
The large fossilised ribs are one of the five fossils used to complete one of the five sub-displays making up the Leviathan in the Varrock Museum's paleontology exhibit.
The other fossils required are the large fossilised limbs, spine, pelvis, and skull.
Each large display completed will give an antique lamp that gives 5,000 experience in any skill that is level 35 or higher, along with 2 kudos.
In addition, they can be used at the mycelium pool to be calcified into a large enriched bone via a chemical process that uses pyrophosphite and calcite. Whilst the reaction is happening in the pool, players must add additional pyrophosphite and calcite to maintain the chemical process, and pop bobbing fossils that surface around the pool, otherwise the fossils will become too exposed to air and dissolve. Once completed, players can open the sluice gate behind the Ancient Shroom, and check the rinsing pool to obtain the enriched bones. They are then used on the easternmost strange machine in the House on the Hill for 1500 Prayer experience.
