To be fossilised it can take anywhere from a few decades to a couple of years.
Dead organisms that were living million / billion/S of years ago.

3 to 4 years undergrad, then 3 or 4 years of Medical school, and then 2 years if you want practice with a surgeon or PhD.
The amount of time it takes for fossils to form is 12,000 years and 1.2 million years. Some scientists have stated that it can take 200 years for some fossils to form.
Bones can continue to repair themselves as long as the person or animal is alive. After death, the bones and teeth are almost always the most persistent body structures. Undamaged bones can persist for thousands or even millions of years if they are preserved from chemical breakdown (as in tar, ice, or similar substances). Many ancient bones became petrified or fossilized through the introduction of minerals into the bone, and can also persist for a very long period of time.
The fossil remains of dinosaur bones come in a different forms. Most have been petrified with calcium, yielding a stony texture and appearance. Agatized bones were petrified with silica or quartz, which gives the bones a glassy and colorful look.
Petrified Wood Mountain is significant in geological history because it contains a large deposit of petrified wood, which is fossilized wood that has turned into stone over millions of years. This fossilized wood provides valuable information about ancient forests and climate conditions, helping scientists understand the Earth's history and evolution. Additionally, the presence of petrified wood in this mountain indicates past volcanic activity and the process of petrification, shedding light on the geological processes that have shaped the landscape over time.
The tar pits, which yielded many fossilized dinosaur bones many years ago.
True
If you meant 'petrified' - Some examples could be :- Jack was petrified with fear - The petrified tree was over 10,000 years old
the petrified trees of the petrified forest date back to?
True
When an organism dies, it can become buried in sediment which helps protect it from decay. Over time, minerals from the surrounding environment can seep into the organism's tissues, gradually replacing them and forming a fossil. The process of fossilization can take millions of years.
Firstly, your premise is incorrect in that oil is not a product of fossilized bones, and even if it were true, "millions of years" ... the question kind of answers itself, doesn't it?reply to answer:No sir you need to do a little more research before you respond. Oil is a product of dead animals, and organic undersea plant life that has been under the earth for millions of years. That question was asked and answered prior to my question. Now if those bones were a product of compression and heat under the Earths surface why is there no oil under cemeteries?
By being petrified over millions of years.
Animals with bones or shells can be found many years because these structures are hard and durable, making them resistant to decay. Fossilization processes can also preserve these structures over long periods of time, allowing them to be discovered by researchers many years later.
