why aren't flowering plants in the lowest layers?

Mark posed another unanswered question about the geological column, or at least I missed the answer if there was one. Perhaps we can piggyback these two together.The question concerned the worldwide geological layer containing elevated iridium levels, and how that could have happened due to Noah's flood.--Percy

Me and Joe Meert tumbled around it but I think that either Mark24 was confused when he typed up the question or it was something else. (irridium is a heavy element)

I couldn't follow your proposed scenario. Could you explain it again at, say, a 4th grade level? If I can just get a general idea of what the proposed events were and the order that they happened that would be great.--PercyEdited by Percy, : Modify/rerender to get rid of old-style reference to discussion board pages.
