"The amount of dinosaur carcases needed to create the Saudi Gawar (sp?) oil field would have needed to be about 9-miles high, 9-miles wide, and 9-miles long according to one study I read, and that kind of clinched it for me."
You really find this a compelling argument? Dinosaurs existed for 160 million years. With 5280 feet per mile, that's about 920 cubic feet of dinosaur carcass per year. A brachiosaur was about 85 ft long and 40 ft tall. Conservatively, that's just a couple brachiosaur carcasses per year.
Nevertheless, the argument itself is actually just a straw man. No theory says that oil comes from dinosaur carcasses; its plankton and small marine organisms, which are superabundant.
Note that the 9x9x9 cubic miles of living organisms is small when compared to other large scale natural remnants of living organisms. Coral reefs, for example, cover about 284,300 square kilometers of the earth's surface.
