What happens to the fossilized remains during the sediment compaction process?

During the sediment compaction process, the fossilized remains are subjected to immense pressure from the overlying sediments. This pressure forces the sediments together, resulting in compaction and often leading to the lithification process, where loose sediments are transformed into solid sedimentary rock. As the fossilized remains become embedded in these compacted layers and subjected to the changing mineral environment, the minerals present in the surrounding sediment can precipitate and fill the spaces between the fossils, effectively 'fusing' them into the rock matrix. This process preserves the fossils in a stable form within the rock, allowing them to be studied millions of years later. Thus, the correct answer highlights how fossilized remains integrated into sedimentary rock through compaction and mineralization.
