Re: [Geology2] Re: World's Largest Extinction Explained by World's Largest Volcanic Eruption

My goof.... you are right.... I got my oil and coal switched in the head..... hey, I'm 40 now and it's going to happen more frequently.

Yes, coal is swampy land stuff mostly while OIL is marine-based..... sorry about that Dean and thanks Schmartz99 for clearing my head up.
