Answer:
It takes millions of years.
Explanation:
As when a dead animal is buried it should reach sedimentary rock
Depending on the size of the animal, skull, or bones you are burying, it will take three months to one year for all the skin and tissue to decompose and just leave the bone(s) behind. Maceration is the process submerging the carcass in water to start a bacterial soup to decompose.
