When something fossilizes, it becomes a fossil, meaning it leaves an impression in the Earth that far outlives the organism. Fossils are remnants left in rock of a living creature: the remnants have been petrified over many years and they leave an impression of what the animal was like.

Fossils are defined as the remains or traces of organisms that died more than 10,000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10,000 years.
