The dead animals of the sea or large lakes and of the land carried to the sea or large lakes carried to the rivers and sinks down then get buried in rocks. The oxygen get low which prevents from decay and the animals which preserved in rocks. Thus the hard parts remains of the dead animals and that forms fossils.
