Why Are Fossils Preserved In Sedimentary Rocks Only at Pamela Bentley blog

Why Are Fossils Preserved In Sedimentary Rocks Only. There are exceptions, where bones and teeth have been preserved for millions of years,. Finally, the sedimentary rocks are the one type which can contain fossils because these rocks are formed on the earth surface, under the water, at very low temperatures and pressures. Internal and external molds are often found in association, however, particularly if slightly acidic ground water has dissolved away the calcitic or aragonitic shells, but left behind the surrounding. Soft tissue is hard to preserve because it needs to be buried before bacterial decay can occur. While the formation of sedimentary rock is perfect for the preservation of fossils, the formation of igneous and metamorphic rock isn’t. The majority of the fossils found in sedimentary rock are imprints rather than original matter. Fossils become part of sedimentary rocks when sediments such as mud, sand, or silt from the sea and river beds surround an organism and preserve its body over time. Earth’s oldest fossils are only preserved as complex organic molecules.
