Either way, whatever you decide to use your fossils on, you’re going to need to have a general understanding of how to use them.

What To Do With Fossils in Old School RuneScape

There are four different types of unidentified fossils in Old School RuneScape; unidentified small fossils, unidentified medium fossils, unidentified large fossils, and unidentified rare fossils.

Turning Unidentified Fossils into Cleaned Fossils

As of now, there are only two ways to clean fossils; using unidentified fossils on a cleaning bench or a specimen table. If you would like to use a cleaning bench, then you’re going to have to build one near the Museum Camp located at Fossil Island.

To build a fossil cleaning bench, you must have five planks, five nails, a hammer, and a saw in your inventory. If construction is not your cup of tea, then you could use a specimen table located on the bottom floor of Varrock Museum.

In order to clean unidentified fossils, you’ll need to be wearing leather boots and leather gloves. You’ll also need to have a trowel, a rock pick, and a specimen brush in your inventory.

All of these items can also be obtained by taking a cleaning kit that is located near the specimen table at the Varrock Museum or the cleaning bench at Fossil Island.

Once you’re ready, simply just use the unidentified fossils on your cleaning station of choice to clean your fossils.

After you’re done cleaning your fossils, you can put them in the fossil storage that is located near the cleaning bench in Fossil Island or next to the flight of stairs on the bottom floor of Varrock Museum.

The fossil storage saves across all locations, so if you put fossils inside the fossil storage in Fossil Island, the fossils will still be at the fossil storage in Varrock Museum.

Now that you’ve cleaned your fossils, let’s go over what you can do with them.

Trading Fossils for Numulite

You can trade your fossils for numulite by talking to the Fossil Collector, who is located at the Museum Camp bank on Fossil Island.

The amount of Numulite varies, but small fossils can be exchanged for 100 numulites. Medium fossils and plant fossils can be exchanged for 200 numulites.

Large fossils can be exchanged for 300 numulites. And rare fossils can be exchanged for 500 numulites.

Calcifying Fossils into Enriched Bones for Experience

In order to calcify fossils, you must use calcite and pyrophosphite. You can calcify your fossils by interacting with the Mycelium Pool, which is found in the northern area of the Mushroom Forest on Fossil Island.

You can calcify either unidentified or cleaned fossils. However, plant fossils cannot be calcified and will be destroyed if added to the pool.

A fossil storage container will be next to the Mycelium pool, so you don’t have to worry about running back and forth from the bank during this process.

To use the Mycelium Pool, click on the hopper, which will open the Fossil Pool’s interface, where you can add fossils, calcite, and pyrophosphate.

In order to begin the enriching process, you must have at least three calcite, three pyrophosphite, and one fossil inside.

Once the enrichment process is done, open the sluice gate. Opening the sluice gate will move the newly enriched bones to the rinsing pool where they can be collected (located behind the Ancient Shroom, north of the Mycelium Pool).

When collecting the newly enriched fossils, you must have enough inventory space to collect them all at once. Otherwise, you’ll be prompted to free up some space in your inventory.

Once you’ve collected your enriched bones, you may use them on the strange machine located at the House on The Hill, which is accessed by the magic mushtree, south-west of the Mycelium Pool.

Using your enriched bones on the strange machine will give you prayer experience. Small enriched bones will give you 500 experience.

Medium enriched bones will give you 1,000 experience. Large enriched bones will give you 1,500 experience. And rare enriched bones will give you 2,500 experience.

Putting Fossils Inside Display Cases at the Varrock Museum for Experience and Kudos

Once you’ve cleaned all your fossils and are ready to put them on display, head on over to the Varrock Museum, if you haven’t already, which is located north of the Varrock east bank.

Once you’re inside, head down to the fossil display area, where you’ll find the fossil display cases and the fossil storage. Click on the fossil storage and take out which fossils you want to put on display.

Remember, if you’re building a small fossil statue, then you must only use small fossils. The same principle goes for medium and large statues.

Head on over to the display area and click on the display case until either you run out of fossils or you finish the fossil statue. Upon completing the fossil statue, you’ll earn two kudos and an antique lamp that’s associated with the size of the display case.

Each fossil display takes five fossils from your inventory and gives you two kudos.

Completing small fossil display cases gives you 2,000 experience. Completing medium display cases gives you 3,500 experience. And completing large display cases gives you 5,000 experience.

Rather than just getting raw experience, you get an antique lamp, which can be used to redeem said experience to any skill of your choice.

That’s what you can do with fossils in Old School RuneScape!
