Skulls are a bony structure that is found inside your head, and in the head of almost all animals. The top part of the skull is called the cranium and the bottom part is called the mandible. Your mandible is more commonly called your jaw, and is the part that moves up and down as you chew or open and close your mouth.
The picture is of the top part of a sheep's skull.

Skunks are medium sized animals best known for their ability to make a really bad smell. They can squirt their stinky substance several feet with great accuracy. The smell is bad enough to scare even a bear away, and a person can smell it from a mile away. The smell is almost impossible to wash out of anything it has touched.
Skunks sleep during the day and night and come out at dawn and dusk to look for food. Skunks eat insects, mice, small lizards, salamanders, frogs, snakes, birds, moles, and eggs. They also eat berries, roots, leaves, grasses, mushrooms, and nuts.
There is some debate about whether skunks are related to weasels or if they are alone in their own family.
