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...
