Ancient bones (The Restless Ghost)

Ancient bones are obtained by speaking to Father Aereck in Lumbridge Church after completion of The Restless Ghost quest. If you have already completed the quest prior to these bones being added to the game, you can receive them simply by talking to Father Aereck again.

Father Aereck gives the player 5 of these bones as a reward and each bone gives 200 prayer experience when buried.
 * When used on the Wise Old Man he will say that he wouldn't know whether you should keep it or not since he can't identify items from members-only quests although the bones are obtained after completing the free-to-play quest The Restless Ghost.

Ancient bones are the best bones at the moment, beating Frost dragon bones by 20 exp. However, only 5 can be obtained from the Restless Ghost quest. They cannot be ground at the Ectofuntus or offered at an gilded altar.

Trivia

 * Originally, you didn't obtain Ancient Bones as a reward for the Restless Ghost quest. Jagex added these bones to the reward to help players get used to burying bones.
 * During the Bonus XP weekend of 12–14 March 2010, ancient bones could be buried for a maximum of 540 experience points, although quest experience rewards didn't multiply.
 * If you have the Game button set to filter on your HUD, the message "You dig a hole in the ground. You bury the bones", will still appear when you bury the bones even though the game is set to filter.
 * If you try to grind Ancient Bones at the Ectofuntus, you will get a message saying"You have no bones suitable for grinding" or if you use the bones on the hopper at the Ectofuntus it will say "These bones are too special to grind."
 * Ancient bones cannot be used with a gilded alter to grant extra xp.
