Bone

A bone is an item dropped by skeletons and Wither Skeletons upon death. It can also be found in chests hidden on pyramids.

Uses
Using a bone on a wild Wolf has a 33% chance of taming. Bones cannot pacify an angry wolf.

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.

As a crafting material
Bone creates 3 Bone Meal when put in the crafting table. Bone meal can be used for dyes, and for growing plants more quickly.

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.
