Fossils are preserved in two main ways: with and without alteration. Preservation with alteration includes carbonization, petrifaction, recrystallization and replacement. Preservation without alteration includes the use of molds and the collection of indirect evidence.
Carbonization
Carbonization often occurs in the preservation of plants and soft organisms. The remains of the plant or animal are crushed beneath the weight of the rock. The gases, including hydrogen, nitrogen and oxygen, are off gassed through the process of heat and compression. What is left behind is a carbon film, an impression of the former living thing.
Petrifaction
Sometimes referred to as permineralization, petrifaction occurs when a porous material such as a bone or shell becomes filled with preserving material such as calcium carbonate or silica. The original shell or bone becomes buried below the ground and water penetrates the surface. The groundwater contains the calcium carbonate that fills the empty spaces in the material, which over time, hardens and fills the pores full of minerals that preserve the item.
Recrystallization
Recrystallization often occurs in shell fossils and is the process by which the small molecule crystals inside a shell often formed of one type of calcium carbonate can transform to another type of calcium carbonate. This stabilizes the shell and turns it into a fossil.
Replacement
Occurring in both shellfish and wood, replacement is when the atomic composition of the original living thing is replaced cell by cell by a new chemical structure. Typically, the chemical that replaces the original is determined by the groundwater the fossil is lying in. A common type of replacement is silification. This is when the original living remains are replaced with silica as in the case of petrified forests.
Casting
Casting and molding are an indirect way of preserving fossils. In this case, indirect means that the chemical composition of the organic matter does not change, rather it lays in a substance that makes an impression of the matter. Common examples include castings of fern leaves and snail shells.
Trace Fossils
Trace fossils are another type of indirect preservation of fossils. Examples of trace fossils are footprints and trails. Dinosaurs and other prehistoric animals moved through the undergrowth and along top soil that was later covered with other debris. In some cases their tracks were preserved and can be dug up and cut out of the ground. Another example of a trace fossil is animal dung. Preserved, fossilized dung provides fossil experts with evidence of ancient food sources and the structure of prehistoric digestive system.
To convert into a fossil.
A preserved fossil is an organism or Animal that has been PERFECTLY PRESERVED for lots of years, or however old it may be. For example, a wooly mammoth frozen in the ice for millions of years would be known as a preserved fossil.There are 2 different types of fossil preservation- preservation with alteration and without. With alteration also has different types. The type of organism you are looking for depends on the how it was preserved.
A Paleontologist is one who studies prehistoric life (Fossil's, organisms etc)
Conservation is an action to conserve something or someone. Preservation are steps that you complete to save something or someone.
Probably the best condition for fossil creation/preservation would be aqueous catastrophism(ie... flood), stratum deposited in rapid succession. Quick coverage of plant or life form would/do present terrific fossils.The answer of 'Quick freezing' is not so likely. I can't think of anywhere there would suddenly be 'flash freezing' upon our planet. Life forms would have a chance to move away from such conditions of cold and plants would die out. Although death within a cold temperature area would lend to good preservation of a life form."Quick Freezing"
yeppers
The fossil records have eroded due to lack of proper preservation.
Permineralization.
Carbon film
(Konservat-Lagerstätten) - fossil deposits where preservation is remarkable because of the unusual quality.
I want to know about compartmentalization in food preservation technique
No. Preservation as a fossil is most likely when the organism is buried quickly. Slow burial gives opportunity for decay and other destructive processes to occur.
fossil rock has to be sedimentary, never igneous nor metamorphic, it contains dead very old plants, creatures any kind..... and that suggests a suitable environment for preservation; quick burial and no air existence also not a very high temperature to keep the shape of the fossil.
preservation viewpoint means the belief that all parts of the environment are equally important no matter how useful they are to humans.
Answer:If you mean in Pokemon, there is no other fossil like it, and it becomes an aerodactyl.
