Fossil Beads and Mineral Beads

A fossil is the impression left when the body of an ancient animal or plant is encased in some type of mud or sand. After great expanses of time, the ancient animal or plant turns into rock when the matrix around the object has become firm enough to hold its shape. The object itself is slowly replaced by some other mineral that works its way in from the surrounding matrix. If nature cooperates, the rock or mineral formed where the body used to be is different enough in composition from the surrounding rock or mineral that one can separate them to rediscover the original shape of the object. A fossil can be formed out of all kinds of different minerals, so there are really two entirely separate ways to describe one What it`s a remnant of, and what it`s made out of.
