The Mysterious Origin and Supply of Oil.


A so-called fossil fuel, petroleum is believed by most scientists to be the transformed remains of long dead organisms. The majority of petroleum is thought to come from the fossils of plants and tiny marine organisms. Larger animals might contribute to the mix as well.


"Even some of the dinosaurs may have gotten involved in some of this," says William Thomas, a geologists at the University of Kentucky. "[Although] I think it would be quite rare and a very small and insignificant contribution."


But another theory holds that more oil was in Earth from the beginning than what's been produced by dead animals, but that we've yet to tap it.
