Revision as of 01:31, May 12, 2018

Fossils are items on Fossil Island that are used to build displays on the bottom floor of the Varrock Museum (below the natural history floor). Completing a display requires a complete set of one type of fossil (i.e. small/medium/large/rare) and grants 2 kudos and an experience lamp based on the type of category of the fossils. They can be sold to the Fossil Collector in exchange for numulites, or used on the mycelium pool to create enriched bones which can be further processed to eventually gain some Prayer experience.

Obtaining Fossils

Fossils may be obtained from Mairin's Market and from certain actions that roll the fossil drop table.

Every time you roll the fossil drop table, there is a chance you may receive either a fossil, numulite or nothing.

If you receive a fossil, the chance of you receiving each kind of fossil is as follows:

Fossil type Drop chance
Unidentified small fossil Unidentified small fossil 50%
Unidentified medium fossil Unidentified medium fossil 25%
Unidentified large fossil Unidentified large fossil 20%
Unidentified rare fossil Unidentified rare fossil 5%

The fossil drop table is as follows:

Strategy

This guide makes the assumption that an unidentified large fossil will turn into a large fossil 50% of the time, and a plant fossil 50% of the time.

In order to complete the Varrock museum, you will need approximately 55 unidentified large fossils (95% confidence interval 50-65) in order to get 25 plant fossils and 25 identified large fossils, 60 unidentified medium fossils and 70 small fossils. The rate-limiting step are the unidentified large fossils.

Thieving and Mairin's Market

If you are using Mairin's Market, you should save your points and then evaluate the specific fossils you need to achieve your total of 25 plant fossils, 25 large identified fossils and 60 medium fossils.
