When people say “fossil fuels” they think of fossils, which makes them think of dinosaurs, which makes them think fossil fuels are made of dinosaurs. But that is far from truth. Actual dinosaurs make up a teeny, tiny percentage of fossil fuels, which really represent the carbon leftovers of ancient moss and other plant matter. Think of how much biomass you get when you rake leaves a few times a year. Multiply by the earth’s surface, and that by millions of years. If a few lizards found their way into the pile, fine. “May contain dinosaurs.”
