The answer is: Following step 3, sediments accumulate over the deceased organism. Fossilization is the process through which organisms are preserved as impressions in sedimentary rock. This occurrence is quite rare and necessitates specific conditions. Permineralization, one of the common fossilization methods, involves minerals permeating remains, creating detailed impressions of the organism. Once an organism perishes, it sinks to the ocean floor. While soft tissues decompose, harder structures like nails, bones, and hair endure. Subsequently, these bones are progressively enveloped by sediment, with fossil quality often hinging on sediment type and volume. River deltas offer abundant sediment, expediting fossilization. Clays and mud facilitate greater fossil detail, whereas sandy sediments obscure it. Sedimentation is succeeded by permineralization. As layers of sediment build up, the pressure turns the lower layers into rock due to mineral movement that solidifies the sediments. Minerals like calcite might replace bones and other durable parts, enabling long-term preservation. Fossils excavated by archaeologists are typically found nearer to the Earth's surface due to the uplift of rock layers caused by shifting continental plates.
