How is fossil limestone lithified
WebLithify and Fossilize The shallow warm seas supported enormous populations of invertebrates, fish, amphibians and plants. These creatures took calcium carbonate (CaCO3) out of the water and secreted it, forming shells or skeletons. As these organisms died, they sank to the sea floor where the organic parts decayed. WebEssentially, lithification is a process of porosity destruction through compaction and cementation. Lithification includes all the processes which convert unconsolidated sediments into sedimentary rocks.
