Thermohaline circulation moves water between warmer and cooler, and saltier and less salty, areas of the ocean. The principle of faunal succession, also known as the law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances.a fossilized neanderthal bone will never be found in the same stratum as a fossilized.
