Explanation:
<span>Answer: Far smaller and far slower social changes in earlier periods triggered civil wars, rebellions, and violent intellectual and spiritual crises. The extreme social transformations of this century have caused hardly any stir. They have proceeded with a minimum of friction, with a minimum of upheavals, and, indeed, with a minimum of attention from scholars, politicians, the press, and the public. To be sure, this century of ours may well have been the cruelest and most violent in history, with its world and civil wars, its mass tortures, ethnic cleansings, genocides, and holocausts. But all these killings, all these horrors inflicted on the human race by this century's murderous "charismatics," hindsight clearly shows, were just that: senseless killings, senseless horrors, "sound and fury, signifying nothing." Hitler, Stalin, and Mao, the three evil geniuses of this century, destroyed. They created nothing.</span>
It varies depending on the environment where it fossils and the type of organism:
1-Conservation of organs without modification or with discrete modifications (recrystallization). Is the usual case of hard parts (shells, bones, teeth, calcareous algae ...), and exceptionally soft parts in very particular conditions: ahem. mammoths conserved in icy soils of siberia or in hydrocarbons (ozokerites) north of the Carpathians, insects included in fossil resins (baltic amber).
2-Conservation of organs after their replacement by a different subject preserbando its structure with more or less detail. (It is a process called metasomatism) ahem. silicification of trunks of trees, vertebrate bones or the pyritization of ammonites.
3-Conservation in the form of mold of the organism, internal or external to it. It is often the case of ammonites, shells or conches.
The fossilization process is said to start at 100ºC and pressures above 1Kb (kilobar). Conyeva an exchange of atoms, between the original organism and the matter that surrounds it. They are called fossiligenetic processes. Some of the processes are: carbonation, silicification, phosphatization, pyritization, dissolution.
