No, dumb ass, nor has any scientist ever said that. It was produced from single celled life buried in organic sediment.

ORGANIC ORIGINS OF PETROLEUM
Petroleum is a naturally occurring substance consisting of organic compounds in the form of gas, liquid, or semisolid. Organic compounds are carbon molecules that are bound to hydrogen (e.g., hydrocarbons) and to a lesser extent sulfur, oxygen, or nitrogen. The simplest of these compounds is methane with one carbon atom bound to four hydrogen atoms (Figure 1). Asphaltenes are the most complex with more than 136 carbon atoms bound to more than 167 hydrogen atoms, 3 nitrogen atoms, 2 oxygen atoms, and 2 sulfur atoms (Figure 1). Petroleum gas is referred to as natural gas, which should not be confused with the abbreviated term used to describe the refined fuel "gasoline". Natural gas consists predominantly of simple hydrocarbons with only one to five carbon atoms (i.e., methane to pentane, respectively, Figure 1). Liquid petroleum is referred to as crude oil and consists of a wide range of more complex hydrocarbons and minor quantities of asphaltenes (Figure 1). Semisolid petroleum is tar, which is dominated by larger complex hydrocarbons and asphaltenes (Figure 1).
Figure 1. Some examples of organic compounds in petroleum, from the simplest (methane) to the most complex (asphaltene).
Petroleum formation takes place in sedimentary basins, which are areas where the Earth's crust subsides and sediments accumulate within the resulting depression. As the sedimentary basin continues to subside, sediment accumulations continue to fill the depression. This results in a thickening sequence of sediment layers in which the lower sediment layers eventually solidify into sedimentary rocks as they experience greater pressures and temperatures with burial depth. The sediment layers that accumulate vary in character because the sources and depositional settings of the sediments change through geologic time as the sedimentary basin subsides and fills. It is critical to petroleum formation that at some time during the accumulation of sediments at least one of the sediment layers contains the remains of deceased plants or microorganisms. Throughout geologic time, the world oceans have expanded and receded over the Earth’s land surfaces and contributed sediment layers to subsiding sedimentary basins. Development of stagnant water conditions in some of the expanded oceans caused the bottom waters to be depleted in oxygen (anoxic), which allowed portions of decaying plankton (e.g., algae, copepods, bacteria, and archaea) that originally lived in the upper oxygen-bearing (oxic) waters to be preserved as a sediment layer enriched in organic matter (Figure 2). Swamps and marshes may also develop marginal to oceans overlying subsiding basins. In these depositional settings, sediment layers enriched in decaying land plants (e.g., trees, shrubs, and grasses) may occur.
As these organic-rich sediment layers are buried by deposition of overlying sediments in the subsiding basin, the sediments are compressed and eventually lithified into rocks referred to as black shale, bituminous limestone, or coal. Methane producing microorganisms referred to as methanogens may thrive under certain favorable conditions within the organic-rich sediment layer during its early burial. These microorganisms consume portions of the organic matter as a food source and generate methane as a byproduct. This methane, which is typically the main hydrocarbon in natural gas, has a distinct neutron deficiency in its carbon nuclei (i.e., carbon isotopes), which allows microbial natural gas (a.k.a., biogenic gas) to be readily distinguished from methane generated by thermal processes (a.k.a., thermogenic gas) later in a basin's subsidence history. The microbial methane may remain in the organic-rich layer or it may bubble up into the overlying sediment layers and escape into the ocean waters or atmosphere. If impermeable sediment layers, called seals, hinder the upward migration of microbial gas, the gas may collect in underlying porous sediments, called reservoirs (Figure 3).

If you think about it, dinosaurs must have lived on Saturn's moon Titan for a billion years before they migrated to Earth. The surface temperature on Titan is a couple of hundred degrees below zero so it would have taken an extra billion years to transform the dinosaurs into fossil fuels there.
I also wonder why intelligent life hasn't "evolved" on Titan either. It has sunlight, a liquid medium and gobs of raw materials. Does the force of "Evolution" not reach all the way out to Titan?

Nobody has to do that, is it is not the same type of oil. Which you might know, if your lazy ass had read a single word of the article this thread is about.

Coal and oil are not methane and ethane, genius.

So you weren't referring to the above article that did discuss methane?

LOL Stupid ass. Look at the short video with Richard Alley explaining how coal and oil are formed. The plants that form oil are single celled organisms. LOL

I never said that dinosaurs were the source of oil, although the source was millions of years of decaying vegetation.
