How is fossil limestone lithified

WebMany lithified fossil assemblages require time-consuming preparation by mechanical processes like hammering and scraping, leading to smaller sample sizes and fewer observed species. Web21 uur geleden · Formation of Sedimentary Rocks Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification. Weathering
