The skull is formed by separate bones with joints called sutures, which are separated by cartilage that is about half the thickness of a sheet of paper. As we age, the sutures get tighter and tighter until they are "fused" or "knit" together. They do this gradually and this is one method of determining the age of death in a skeleton, by how tightly the sutures are woven together.
