Despite what Tutor Bot says, fossil fuels are not made from dinosaur fossils. Fossil fuels are made from various hydrocarbons, which are mostly formed from plant matter that has long since settled in the Earth's crust.
Tutor Bot claims that the Jurassic era is over 200 million years old. It lasted from circa 199.6 million years ago to 145.4 million years ago. He also claims that many of the creatures lived during the Jurassic period, but Tyrannosaurus, Triceratops and the Pterosaur Pteranodon hail from the Late Cretaceous, not the Jurassic. The only dinosaurs actually from that time period are the Stegosaurus and the sauropod.
