Cast Fossils: an imprint that is filled in, then fossilized Permineralization: process in which an organism dies and sediment enters the body, filling in the pores of a leaf, or a bone or a shell Whole Body Preservation: occurs when the total organism is fossilized; may occur through freezing or falling in tree amber
A fossil (from Classical Latin fossilis; literally, obtained by digging) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, hair, petrified wood, oil, coal, and DNA remnants.
