Bone

A bone is an item dropped by skeletons and Wither Skeletons upon death. The amount of bones dropped varies from 0-2 bones.

Uses
Bones can be used to tame wild wolves. It will usually take more than one bone to tame one wolf.

Bones can be used to make bone meal, which serves three purposes:
 * It can be used as a fertilizer for farming that immediately makes plants grow to their mature state.
 * It can also be used to grow tall grass, flowers and mushrooms. When used on mushrooms they become as tall or taller than trees. However, bone meal is not guaranteed to work 100% of the time when used as a fertilizer.
 * It can act as a dye that colors a sheep's wool white and can be combined with other dyes. However, there is no way to craft bones. They are only dropped by killing skeletons.

As a crafting material
Bone creates 3 Bone Meal when put in the crafting table.
