Agree. I have said for years that there could not possibly be enough plants and dinosaurs that died to create the billions and billions of oil that exist today.
Every day we consume 19 million barrels of oil, every single day!
How many brontosauruses is that?
No appreciable amount of oil has come from dinosaurs, which like a deer on the side of the highway, were scavenged by the buzzards, fire ants, worms, and the like of their day. Oil comes primarily from algae, which lives in the photic zones of the oceans. When it dies, it falls to the bottom. Only under certain conditions is the water anoxic (lacking oxygen) so that the buzzard’s equivalent on the bottom of the ocean don’t consume the organic matter. It takes millions of years for a significant amount of material to accumulate and then be buried to around 10,000’ deep for catagenesis to take place.
