Fossils are literally the remains of numerous animals that lived thousands or countless years back. When these animals passed away, they were hidden in layers and layers of earth. While their flesh would certainly rot away, the more challenging components of their body, such as shells, bones, etc, would stay intact between the layers of sediment. Currently, all those years later, those bones and coverings can still be located, undamaged, as those layers of debris are again uncovered.
