What special conditions do fossils need to form?

Answer 1

answ2. Conditions favourable for good preservation of a fossil include:-

. quick burial

. a fine silt cover (Though lignite or similar often contain good fossils)

. little or no decomposition

. stable geological environment - no metamorphism, folding, crushing.

Some good fossils are found to have had their internal structure replaced by mineral solution. Quite common with wood.

Very occasionally, an insect or animal is preserved in an inaccessible environment, such as the tar pits of la Brea, or Baltic Amber.

Wooly Mamoths and similar are not considered fossils.

Fossils are formed by microorganisms decomposing the remains of an animal or plant. These microorganisms need oxygen to respire, so fossils are left when the material is to hard for the microorganisms to decay when there is a lack of oxygen.

Answer 2

When an animal or plant dies, usually the remains are eaten or decompose. On occasion though, they get buried by mud or sediment, and in the right conditions, they harden into fossils.

The bones or original material decay, and water or other things seep into the impression left by the original material. This water and minerals continue to dissolve the original material, replacing it, and then they harden over time.

So, right condition, pressure of the mud on top it is most needed to form a fossil

Answer 3

Basically the remains or remnants of the organism need to be kept safe from outside forces in order to fossilize. This includes scavengers, the weather, and erosion. They need to be covered by sediment as soon as possible.

Answer 4

Well first you need conditions. After that, in the light of the full moon sing a song of hope. The rocks will hear the hope and danced themselfs into fossils.

Answer 5

Fossils often form through a process called fossilization, which requires specific conditions such as quick burial in sediment to protect the remains from decay, and the presence of minerals that can replace the organic material of the organism. Additionally, low oxygen levels can aid in the preservation of fossils by slowing down decomposition.
