Explanation:
Permineralization
occurs when minerals carried by water are deposited
around a hard structure. They may also replace the hard structure itself.
Natural casts
form when flowing water removes all of the original bone or
tissue, leaving just an impression in sediment. Minerals fill in the mold,
recreating the original shape of the organism.
Amber preserved
are organisms that become trapped in tree resin
that hardens into amber after the tree gets buried underground.
Trace fossils
record the activity of an organism. They include nests,
burrows, imprints of leaves, and footprints.
Preserved remains
form when an entire organism becomes encased in
material such as ice or volcanic ash or immersed in bogs.
Fossils are usually form when an organism dies and quickly get buried by mud, sand or volcanic ash(sediment). Several different physical and chemical processes can create fossils.
What are fossils?
Preserved remains, or traces of remains, of ancient organisms are fossils. Fossils are never a remains of the organism itself. Bones, shells, feathers, and leaves are some of the materials that can easily become fossils.
Few ways by which fossils are formed:
- Freezing, drying and encasement.
- The heat and pressure of inner surface of earth cause tissues of organisms to release hydrogen and oxygen, this leaves residue of carbon behind.
- The most common method of fossilization is called premineralization. Premineralization is blockage of pores of plant materials, bones, and shells by mineral matter.
