Fossilization only occurs under the "right" conditions.
For example, if an animal were to die, and you would come back 100 years later, there would be no fossil.
But, if an animal were to be buried rapidly (Flood, mud, sediments, etc) then that animal can turn into a fossil in a relatively short amount of time.
The fossil "record" is not evidence for evolution, but of the Flood.
