Bone

Bones are items dropped by skeletons and Wither Skeletons upon death. They can also be found in chests hidden in Desert Temples and Jungle Temples. They may also be obtained by fishing.

Uses
Using a bone on a wild Wolf has a 33% chance of taming it. Bones cannot tame an angry wolf or a wolf that someone else has tamed.

Bones can be used to make Bone Meal, which serves two main purposes:
 * As a fertilizer, which grows many plants to their fully mature state after 2-5 uses.
 * As a crafting ingredient in Wool Dyes. It can also make sheep white.

Trivia

 * As with Sticks, Bones are wielded as a tool instead of an item.
 * The bone appears to be the femur, the humerus, or the tibia of a human, however is more likely to be the femur, because the humerus and tibia are slightly curved. this does not rule out the possibility of it being either of those two, however.
