I’m not sure you understood my reply. I was playing devils advocate for the most part. The entire argument being presented is still operating on the assumption that crude oil is just old dinosaur bones. Or something? I guess I don’t know why anyone would think that the forces and processes involved with how this stuff forms would leave all the calcium from animal bones right there in the mix, unless it’s still a misunderstanding. This stuff was comprised almost entirely of plant life anyways, not things that had bones.
