Answer: A fossil is defined as the wreckage or trace of an organism that died more than 10,000 years ago. Therefore, by definition, the minimum time it takes to create a fossil is 10,000 years.
What are the three things needed for a fossil to form?
There are three prerequisites that must be met before storing organic matter. (1) Organisms must contain hard parts such as bones, teeth, cartilage, and shells. (2) Organic matter needs to be quickly buried in an oxygen-free environment protected from scavengers.
Why is it difficult for fossils to form?
In order for an organism to become a fossil, it must not be decomposed or eaten. .. The sooner an organism is buried, the less it rots and the more likely it is to be preserved. Hard parts of living things such as bones, shells and teeth are more likely to become fossils than soft parts.
