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
Fossils are the remains and traces of ancient organisms. A cluster of fossil ammonites, an extinct cephalopod. fossil (latin for obtained by digging) is the preserved remains or traces of organisms (plants, animals, etc) that lived in the distant past.
