Bone

The regular bone from vanilla Minecraft is also present in Middle-Earth.

The mod also adds other types of bones, which can be found at their respective pages. These types are Orc bones, Troll bones, Dwarf bones, Elf bones, Hobbit bones and Warg bones.

Obtaining
Bones can be obtained by slaying any kind of Man, both good or evil. Thus, you can obtain bones by slaying Rohirrim, Rangers of the North, Rangers of Ithilien, Dunlendings, Gondorians, Near Haradrim, or Bandits. About 50% of Men will drop a bone when slain.

Sometimes, you can find bones in the chests of structures such as Rohan Barrows, Gundabad Orc Camps, and Uruk Camps.

Bones are one of the few NPC drops that can easily be obtained, regardless of your alignment.

Uses
Bones can obviously be ground down into bonemeal to fertilize crops. But in addition to this, you can also sell these bones to Orc or Uruk Traders for one silver coin apiece, giving evil players a steady source of wealth.

Bones are also used to activate Morgul Portals, brew Orc Draughts and prepare a Torog Stew.

At present these bones are the only kind of bones that can be used to tame wolves, and it is likely to remain that way, because wolves, like bones, come from vanilla Minecraft, and in order to make wolves tame-able using other types of bones, Mevans would have to make a separate LOTR wolf. Besides, who needs to use wolves in combat when you can hire units instead?
