Wyvern bonemeal (simply bonemeal in game) is the potted dust of wyvern bones created as a result of grinding the bones at the Ectofuntus. Wyvern bones are dropped by Skeletal wyverns, which require a Slayer level of 72 to kill. When used at the Ectofuntus altar with Ectoplasm it gives 200 Prayer experience.

This can also be obtained, at up to 39 a day, by giving unnoted wyvern bones to Robin in Port Phasmatys after the completion of the medium Morytania Tasks, along with an equal amount of buckets of slime. 13 bones can be traded per day after the medium tasks, 26 after completing the hard tasks, and 39 after having completed the elite tasks.

Wyvern bonemeal is also used as an ingredient in creating Super prayer potions, which grants 270 Herblore experience. A Herblore level of 94 is required to make a Super prayer potion.
