Question

What is Fossils formation?

Answer 1

$\huge \bf{Fossil \: Formation.}$

Fossils are formed layer by layer in a sequence. It is a slow process that is totally dependent on where the organism dies. Generally, fossils are formed from the hard parts of the organism, such as tree, trunks or skull.

Answer 2

Answer:

Fossils are the record of life preserved in monuments of stone. Almost all living organisms can leave fossils, but usually only the hard parts of plants and animals fossilize. Soft internal organs, muscle, and skin rapidly decay and are rarely preserved, but the bones and shells of animals are good candidates for fossilization. Almost no fossil record exists for soft organisms such as jellyfish and worms.

Explanation:

Fossils include the footprints of animals left in soft mud, later to be buried, and turned into stone. In some areas herds of fossilized tracks have been found such as at the Johnson farm in St. George, Utah. One of the more exotic fossils is that of swimming tracks made by animals as they brush against the mud and silt floors of an ocean or lake. Under certain circumstances fossils of animal dung, eggs, and even complete nests with eggs have been preserved in stone.

Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock. As the encased bones decay, minerals seep in replacing the organic material cell by cell in a process called "petrification." Alternatively the bones may completely decay leaving a cast of the organism. The void left behind may then fill with minerals making a stone replica of the organism.
