Fossil Island

Fossil Island is a recent update to Old School Runescape. It is an ancient, unexplored island currently being investigated by the researchers of the Varrock Museum, which is the main focus of the Bone Voyage quest. The island lies north of Morytania and unveils a unique uncharted environment where players can train the mining, farming, hunter, crafting, agility, fishing and thieving skills.

Transportation
Fossil Island can only be accessed after completing the quest Bone Voyage. During the quest, the player must steer the barge to the island - after completing the quest, travel to Fossil Island is instantaneous.

The fastest way to travel to Fossil Island is to use a Digsite pendant, which will teleport the player next to the barge at the Digsite. After completing Bone Voyage, a pendant can be used on the strange machine at the house on the hill, north of the Museum Camp. This will allow your Digsite pendant (and all future pendants) to teleport directly to Fossil Island.

Museum Camp

After arriving on Fossil Island, the player will be just west of the Museum Camp. At first, the camp will not be very useful, but players can utilise their Construction skill, a hammer, and some materials to build improvements within the camp. These improvements include: (Total items needed are as follows: 10 Oak Planks, 3 Iron Bars, 25 Nails, 1 Tinderbox, 2 Logs, 3 Soft Clay, 1 Bucket, 2 Ropes and 5 Planks. (DON'T FORGET YOUR HAMMER!)
 * A bank chest: 2 Oak planks, an iron bar, and 5 nails
 * A cooking fire: A tinderbox, 2 logs, an iron bar and 3 soft clay
 * A water source: 2 Oak planks, an iron bar, bucket, rope, and 5 nails
 * A loom: 2 Oak planks, rope, and 5 nails (requires 29 construction)
 * A spinning wheel: 4 Oak planks, 5 nails (requires 28 construction)
 * A fossil cleaning station: 5 regular planks (several are laying scattered around), 5 nails

After building every camp improvement, players can speak to an NPC called Peter just west of the rowboat for a reward of 5 unidentified fossils.

Underwater Area
Full article: Underwater (Fossil Island) Fossil Island has a large underwater area that can be accessed by travelling to the north coast - there are various rowboats around the island, including the one at the base camp. Travelling with the rowboat brings you to a small island with a bank chest, where you can then travel back or right click on the rowboat to enter the underwater zone.

When in the underwater zone, a small bar indicating your oxygen level appears at the top left of the screen. This bar will continually drain while you remain underwater - if it runs out, you'll reappear at the surface. You can refill your oxygen by collecting pufferfish, which can be consumed to refill your oxygen. However, if the player has a fishbowl helmet and diving apparatus equipped, their oxygen level will stay at 100%. The helmet and apparatus can be safely removed and re-equipped while underwater, and if you have an oxygen level below 100%, it will slowly fill back up once both items are re-equipped.

Mushroom Forest

Tar Swamp

The southwest section of the island contains a large swamp. There are various mushrooms that can be chopped down for Woodcutting xp within, but only one of them will be grown at a time, forcing the player to run past various threats in order to continue to chop the mushroom.

House on the Hill

Located on the northeast side of the island, the House on the Hill can be travelled to by climbing a hill on the south end of the Mushroom Forest. It contains various strange machines, one of which can enchant your Digsite pendant to allow you to teleport directly to Fossil Island. The largest 'Strange Machine' in the room, on the eastern side, will destroy any kind of bones if the player were to use them on it.

To the eastern side of the house on a small peninsula lies the 'Strange Stone', Upon examination the player will read "It seems to have been hit with swords."

Located within the House on the Hill there are several stone chests with a search option. Searching the stone chest will ask for a Numulite. After inserting the Numulite, the chest will give the search option to insert 100 numulites into the hole. Some chests can deal damage upon the insertion of 100 Numulites. Once you have inserted 301 numulites you will receive Scribbled Note. Upon reading the Scribbled Notes you will get the following message: "The whole is greater than the sum of its parts. Similar to that observed in the birthing pool, the spore on this island have the potential to inhabit the host, creating a symbiotic relationship between fungus and creature." Possibly alluding to what's broken out of the Strange Machine...
