Fossils are literally the remains of various creatures that lived thousands or numerous years back. Once these animals passed away, they were hidden in layers as well as layers of earth. While their flesh would certainly rot away, the tougher parts of their body, such as coverings, bones, etc, would stay undamaged between the layers of sediment. Now, all those years later, those bones and shells can still be discovered, undamaged, as those layers of sediment are again discovered.
