ROFLMAO.
Corsi CLEARLY does not mean plankton whe he says "vegetation" in this most recent article, when you look at his previous work.
Here's a previous article of his posted on FR:
http://www.freerepublic.com/focus/f-news/1527613/posts
"The problem is that according to conventional "Fossil-Fuel" theory, dinosaur fossils and ancient forests are supposed to be found in sedimentary rock, not bedrock.... If oil is found where no dinosaurs or ancient forests ever were, then the "Fossil-Fuel" theory may end up having been a fiction all along."
Corsi clearly LITERALLY thinks that the mainstream Fossil Fuel theory he's attacking holds that oil comes from dinosaurs and ancient forests. It's very clear he's completely unaware of what the ACTUAL mainstream fossil fuel theory is and has been for decades upon decades.
It's simply fact that Corsi is an incompetent imbecile who has written a book in a scientific field where he hasn't actually read anything by people that know anything about the field; he's attacking a straw-man non-existent "fossil fuel" theory he got from cartoons.
I tried to avoid big words in the above as much as I could for you; you may want to read slowly, but I think you'll get it eventually.
Actually there is a second possibility; that Corsi isn't a moron, and that he actually DOES know about the actual Fossil Fuel theory of petroleum generation, but he's simply deliberately lying about it and mistrepresenting it because he thinks it makes his arguments sound better to the scientifically uneducated audience of WingNutDaily.
They are animals.
