Skeleton

A skeleton is the body of an animal or person after it has been skinned and butchered.

There are also skeletons of killed humans.

Types
Skeletons come in many types. Animal types are more common, though human skeletons do exist.

Once killed, the following animals/people will leave a skeleton after being skinned and butchered:
 * Aurochs
 * Mouflon
 * Fox
 * Boar
 * Deer
 * Bear
 * Human

Threats
In order to ward off looters, it is common that powerful villages will leave the skeletons of their human victims outside of their palisade/wall as a symbol of what they can and have done to people in the past.

Happiness
Being around a skeleton will quickly drain your happiness. (However, please note that Happiness has no real importance yet [up to date as of World 7]).
