According to many fundies, Dinosaur bones were put here by a tricky God to fool unbelieving evolutionists. Yes, I have actually heard more than one of them say this.
I found an interesting item, BTW: Petroleum and Coal are presently thought to have been initiated by plant masses in the Carbonaceous era - this era long preceded all Dinosaurs. The only fossil records of land life back then were things like early amphibians, giant centipedes and dragonflies, and such.
So I will have to remember that when the witnesses tell me that Dinosaurs were put here to make petroleum.
