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.
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.
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.
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.
The wood in the Petrified Forest became petrified through a process called permineralization. When trees fell and were buried under sediment, mineral-rich water seeped in, replacing the organic material cell by cell. Over millions of years, the silica and other minerals crystallized, turning the wood into stone while preserving its original structure and appearance. This process results in the colorful, fossilized logs seen today.
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.
A petrified tree has turned into a fossilized form of wood through a process called permineralization. During this process, minerals in groundwater seep into the tree's organic material, replacing it and preserving its structure over millions of years. The result is a hard, stone-like substance that retains the original details of the tree, often displaying intricate patterns and colors. Petrified wood is commonly found in sedimentary rock formations and can be used for decorative purposes or studied for insights into ancient ecosystems.
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?
