It's been a long time—66 million years!—since the Cretaceous Period ended in explosive fashion, so there's a lot we don't know about our predecessors atop the food chain, the dinosaurs. Were they hot-blooded or cold-blooded, fast or slow, pack animals or lone hunters? What color were they, and what did they sound like? Could you really use one to make a record player, like the Flintstones did? Luckily, our Jeopardy! correspondent Ken Jennings has just published his seventh Junior Genius Guide, this one all about the dinosaurs! He's here all month to straighten us out on all the Mesozoic misinformation we thought we knew.
The Debunker: Is the Oil in Your Car Made from Dead Dinosaurs?
We call oil, coal, and gas "fossil fuels" because they were produced by the decomposition of animal life from hundreds of millions of years ago. For over eighty years, Sinclair Oil has been playing up this prehistoric connection: using a bright green brontosaurus as its logo, giving away inflatable sauropods to kids, putting talking cartoon dinosaurs in its TV ads, and even calling its premium gas "Dino Supreme." (Now with 15 percent more "Dino"!) Generations of American kids should be forgiven for assuming that the fossil fuels in their plastics and furnaces and gas tanks were actually made of dinosaur fossils.
