This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock. Radioactive decay is spontaneously happening in all rocks. Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.
