Does anyone still believe oil comes from dead dinosaurs?

Not necessarily from dead dinosaurs, but definitely from dead marine plants.

oil is the by product of organic matter, from animals and plant matter from over thousands of years.... so yes dinosaurs, and other critters, and plant matter

Yep wannabe Muslim I do

no

oil comes from trees

No way - Then where did the Flintstones get oil ?

Oil formed from the remains of marine plants and animals that lived millions of years ago, even before the dinosaurs. The tiny organisms fell to the bottom of the sea. Bacterial decomposition of the plants and animals removed most of the oxygen, nitrogen, phosphorus and sulfur from the matter, leaving behind a sludge made up mainly of carbon and hydrogen. As the oxygen was removed from the detritus, decomposition slowed. Over time the remains became covered by layers upon layers of sand and silt. As the depth of the sediment reached or exceeded 10,000 feet, pressure and heat changed the remaining compounds into the hydrocarbons and other organic compounds that form crude oil and natural gas.

The type of petroleum formed by the plankton layer depended largely on how much pressure and heat were applied. Low temperatures (caused by lower pressure) resulted in a thick material, such as asphalt. Higher temperatures produced a lighter petroleum. Ongoing heat could produce gas, though if the temperature exceeded 500°F, the organic matter was destroyed and neither oil nor gas was produced.

It seems more logical than oil coming from living dinosaurs.

I believe that is a common misconception, but we know that it comes from earlier life, most likely along the lines of single celled plant life.

The larger concern should be that it has stored carbon for millions of years, keeping it out of the carbon cycle and our usage of it releases this corbon into the atmosphere when there is no natural capacity to remove it. This results in two very bad things, higher global temperatures and ocean acidification.

No one who has looked into it closely believes that. As it turns out, oil derives from ancient fossilized organic materials, such as zooplankton and algae. Vast amounts of these remains settled to sea or lake bottoms where they were covered in stagnant water (water with no dissolved oxygen) or sediments such as mud and silt faster than they could decompose aerobically. Approximately 1 m below this sediment water oxygen concentration was low, below 0.1 mg/l, and anoxic conditions existed. Temperatures also remained constant.

As further layers settled to the sea or lake bed, intense heat and pressure built up in the lower regions. This process caused the organic matter to change, first into a waxy material known as kerogen, found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons via a process known as catagenesis. Formation of petroleum occurs from hydrocarbon pyrolysis in a variety of mainly endothermic reactions at high temperature or pressure, or both.

That's where oil actually comes from. Were you aware of that?

I thought so, when I was a kid. But then I learned how to change the oil in my car and I found out that oil comes from the autoparts store.
