Unidentified Fossils

Written by All, Grand Exchange, Items


Unidentified Fossils come in different size sets which can be obtained while training on Fossil Island. They must be cleaned and collected then the full set can be traded at the Varrock Museum in exchange for antique lamps.


A player can receive fossils as a drop from monsters, chopping Sulliuscep mushrooms in the Tar Swamp, tracking a herbiboar’s tracks in the Mushroom Forest, looting giant clam shells and treasure chests underwater. You can also purchase one from Mairin in her shop for 100 mermaid’s tears, by mining the boulder while in the Volcanic Mine, looting drift nets, digging in the soil found at the Museum Camp, or by opening a Bowl of Fish

Unidentified fossils are obtained when performing specific activities on Fossil Island.

Peter will also grant 5 unidentified fossils for helping reconstruct the Museum Camp.

You can trade these fossils to the Fossil Collector who will pay 100 numulites.

Unidentified small fossils will give the player a small fossilized limb, spine, ribs, pelvis, or skull.

Unidentified large fossils will grant a player either an identified large fossil or a plant fossil. A plant fossil might be a fossilized root, stump, branch, leaf, or mushroom.

Unidentified rare fossils will give the player a rare fossilized limb, spine, rib, pelvis, skull, or tusk.

When a player has received a full set of fossils, they can be brought to the Varrock Museum and displayed in exchange for an antique lamp which will grant experience in any skill desired.

Players must first build the cleaning bench found east of the Museum Camp by using five planks and five nails while having both a hammer and saw in their inventory. This will grant 100 construction experience.

Cleaning Guide

To clean fossils, players must use the unidentified fossil on the bench while wearing leather boots, leather gloves, a trowel, rock pick, and a specimen brush.

Players can also perform this action at the Varrock Musseum.
