Permineralization - Study guides, Class notes & Summaries

unaltered preservation - Answer - hard parts like shells are unchanged due to calicum carbonate shells carbonization - Answer - drives of water and leaves a thin film of black carbon permineralization - Answer - pores of skeleton (bone/wood) are filled with minerals replacment preservation - Answer - original shell/bone undergoes atom substitution with another mineral molds/casts - Answer - original matter disolves leaving impressions or infillings. Impressions- mold Infilling-cast ...

This summary explains the processes involved in fossilization, which transform organic remains into fossils over geological time. It covers key methods such as permineralization, molds and casts, carbonization, freezing, and chemical preservation, each contributing to different types of fossils. These processes occur when organisms are buried and protected from decomposition by rapid burial, lack of oxygen, or specific environmental conditions. Fossilization not only preserves the physical struc...
