This is roughly correct. There is some reason to suppose that oil
formation is still going on, for instance in the Mississippi Delta.

This seems likely, but I have no basis for certainty on this matter.

I think most economically important oil reserves do date from
Paleozoic times, but I would hesitate to say that oil deposits
in general *always* are that old.

I would place little credance on that "theory" - the guy is pretty
much a crackpot.

forms from the degradation of microplankton when rapidly buried

I disagree here. Folk tales do not fade away on their own. If we
who know do not actively correct these things, they will last
The peace of God be with you.
