For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

What are the conditions required for a plant or animal to become fossilized?
The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition. This does make the fossil record biased because animals with soft bodies are less likely to form fossils.
What are 3 requirements to become a fossil?
There are three prerequisites that must be met before organic material can be preserved: (1) Organisms must contain hard parts such as bones, teeth, cartilage, or shells. (2) The organic material must be buried quickly in an oxygen-free environment protected from scavengers.
What two conditions are necessary for fossil preservation?
Three conditions are required for the preservation of plant fossils: 1) Removing the material from oxygen-rich environment of aerobic decay; 2) Introducing the fossil to the sedimentary rock record (a.k.a., burial); and 3) “Fixing” the organic material to retard anaerobic decay, oxidation or other physical or chemical ...
What conditions favor the formation of fossils?
Two conditions that favor the preservation of an organism as a fossil are RAPID BURIAL and HARD PARTS.
Why extinct plants and animals were not fossilized?
Because of the specialized and rare conditions required for a biological structure to fossilize, many important species or groups may never leave fossils at all. Even if they do leave fossils, humans may never find them—for example, if they are buried under hundreds of feet of ice in Antarctica.
Which condition would increase the likelihood of an animal's remains being fossilized?
For a soft-bodied animal to be fossilized, its body must be protected from decomposition. The body is usually exposed to air and water with a lot of oxygen, so it decomposes rapidly. The animal is likely to be fossilized only if it is buried soon after it dies (or when it is buried alive!).
How do plants become fossils?
Three common methods of fossilization are compression, impression, and molding or casting. Compression fossils are often formed in water, where heavy sediment flattens leaves or other plant parts. The weight of the sediment squeezes out water present in the plant tissue, leaving only a thin film of tissue.
How might I become a fossil?
However, if you want your remains to become a fossil that lasts for millions of years, then you really want minerals to seep through your bones and replace them with harder substances. This process, known as 'permineralisation', is what typically creates a fully-fledged fossil. It can take millions of years.
Which of the following conditions makes fossils more likely?
Hard parts like bones are the most likely to be preserved. It is much harder to preserve soft parts or the organism. The presence of Calcium carbonate which can come from broken and dissolved sea shells acts as a preservative.
How come fossils animals or plants haven't been eaten by other animals?
Fossils take millions of years to make. 6. Why weren't fossilised animals or plants eaten by other animals? They were buried under mud or sand.
How many ways are there for an organism to become a fossil once it is buried?
Fossilization is a very rare process. The chances of becoming a fossil are enhanced by quick burial and the presence of hard parts, such as bones or shells. Fossils form in five ways: by preservation of the remains, permineralization, molds and casts, replacement, and compression.
Do all fossils come from animals that are extinct?
(2) Most fossils are the remains of extinct organisms; that is, they belong to species that are no longer living anywhere on Earth. (3) The kinds of fossils found in rocks of different ages differ because life on Earth has changed through time.
How are animals fossilized?
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.
Can anything become fossilized?
The Likelihood of Fossilization
Bones, teeth, shells, and other hard body parts can be fairly easily preserved as fossils. However, they might become broken, worn, or even dissolved before they are buried by sediment. The soft bodies of organisms, on the other hand, are relatively hard to preserve.
What is the most important step to becoming a fossil Why?
The first step in becoming a fossil is death. Natural causes, such as predation or disasters could have killed creatures that lived long ago (just as it happens today). The second step involves the animal being buried in sediment, preventing it from being eaten by scavengers or decomposed by bacteria.
How do you become a fossil step by step?
Four stages of fossilisation
Stage 1: A dinosaur dies and is buried before the remains are completely destroyed. Stage 2: Over time, layers of sediment build up and press down on the buried remains. Stage 3: Dissolved minerals, transported by ground-waters in the sediment, fill tiny spaces in the bones.
