    Glenn's comments about the sheer number of fossils reminded me also of
    some other very simple problems that really do not get expressed enough.
    There have been a number of recent articles in YEC journals that
    emphasize that plant evolution is a serious problem. I've been amazed
    (even more so than usual) at the lack of basic knowledge of the fossil
    record of many of the authors. As Glenn has just pointed out, given
    how much they talk about the fossil record it is remarkable how little
    aware they are of the actually facts of the record. The presence of
    flowering plant macrofossils and pollen is an amazing example of the
    structure of the fossil record. I've copied something I wrote about
    flowering plant fossils for another list last year after attending the
    Botanical Society of America meeting in Madison last summer. Joel Duff

     

    **********************************************

     

    I was thinking about dating methods, flood geology and fossils today as
    I
    attended a bunch of paleobotany (=ancient plants/plant fossils) talks.
    In
    particular there was a highly anticipated pair of talks (well,
    anticipated for
    a bunch of botanists anyway) dealing with some flowering plant fossils
    found in
    the north eastern China. One talk in particular was a preview of a paper
    that
    will come out in one of the top two scientific journal in the world in a
    couple
    of weeks. I suspect the plant fossil will be on the cover. They
    presenter
    from China presented an overview of a set of flowering plant fossils
    found in
    just the last year from the same rock deposit that they are finding the
    feathered dinosaurs in.

    So what do I find so interesting about theses fossils? Well, its
    uniqueness
    is that this particular fossil is said to represent the oldest flowering
    plant
    known in the fossil record. According to the Chinese the rock layers
    these
    fossils have been found are dated (directly by at least 3 different
    radiometric
    methods) to be between 139-141 million years. The next presenter who
    earlier
    found another flowering plant species in rocks several layers above had
    that
    layer dated to 125 million years . This age 139-141 is the oldest report
    of a
    flowering plant in the fossil record anywhere in the world. What is
    really
    interesting is that flowering plant fossils have been reported in rocks
    dated
    to around 120 million years on several other continents but not earlier.
    So
    in the fossil record we have the "sudden" (over several million years)
    of
    flowering plants. Below this point there has never been seen a flowering
    plant
    (alive today we have 300,000 species of flowering plants).

    So relative to the entire geological column what does this mean? If the
    entire
    column is said to cover over 1 billion year then this means that
    flowering
    plant fossils are restricted to the top 10% of the rocks of the column.
    There
    are many places on earth where there rock even at the surface of the
    ground are
    much older than 140 million years so that means all the layers of rock
    below
    the top contain NO flowering plants (eg. I believe the corn fields I'm
    looking
    at here in Wisconsin are right on top of 400 million year dated rocks
    and no
    flowering plant fossils have been identified in Wisconsin, I believe,
    except in
    one areas where there are some younger rocks).

    Back to the fossils, the preservation of these plants was absolutely
    amazing,
    you could see even the veins on the leaves had been preserved in the
    rock. He
    had the entire plant including roots, stem, leaves and the "flower" but
    this is
    not a flower like you might think. This flower consists only of female
    and male
    parts but NO petals and sepals. This is a prediction of the primary
    theory of
    flower evolution now this any many other recently found oldest flowering
    plants
    are upholding this prediction. One other thing I found amazing was the
    second presenter who had described the plant form the higher layer but
    then
    showed a plant found in Germany that looked to me exactly like the same
    plant.
    He showed how they differed only slightly in their leaves (kind of like
    the
    differences between an oak from NA and an oak from Japan would be very
    similar
    but not identical). Now the really amazing part, that fossil from
    Germany has
    been dated to the 120-120 million year range by a different group a
    couple of
    years ago! And again, at that locality in Germany which has been
    thoroughly
    researched there are other flowering plants above it (I might add that
    as you
    go to layers above you get not only more different types of flowering
    plants
    but they also begin to have other more complicated seeds and flowers).

    What are the implication of this? First of all I have always been struck
    by
    the extreme level of order in the fossil record. We look around and see
    mostly
    flowering plants BUT in the fossil record only the very very top of the
    geological record contains ANY flowering plants. You might think that
    maybe
    below a certain point flowering plant parts don't preserve in the
    sediments
    very well but we have places with rocks at very low in the geological
    column
    that are dated between 300-450 million years that contain massive
    amounts of
    plants that we can even see details of individual cell and even details
    of the
    components of cells walls and finer structure than we have in most
    flowering
    plants and yet in these massive rock layers which have been studies
    quite
    thoroughly also not a single flowering plant has ever been seen.

    I can't help but wonder how a noahic flood picked up all the world
    animals and
    plants and deposited them such that not a single flowering plant ended
    up near
    the bottom 9/10 of the sediments that are hypothesized to have been laid
    down
    by that flood. Even more dramatically, flowering plants produce pollen
    grains
    that are distinctive compared to pine tree pollen and fern pollen and
    pollen
    grains and spores can be found in the fossil record back 400 million
    years but
    NO flowering plant pollen grains have been identified in rock layers
    older than
    something like 140 million years (I'll have to look that up when I get
    back,
    could be a bit older) . This is absolutely incredible if there were
    flowering
    plants before the flood (which I think the Bible suggests there were
    though it
    doesn't mention flowers specifically)! How did all these plants get
    picked up
    with the soil get mixed and then settle into 10 km thick layers of rock
    of
    which maybe only the top 500-1000 meters contain any flowering plant
    pollen or
    flowering plant fossils? One could hypothesize that flowering plant
    pollen
    could sort differently than fern pollen but you can test this hypothesis
    at
    home. Simply take some sand, pollen from a pine tree (abundant right now
    in
    some places), spores from a fern, and some pollen from some flowering
    plants
    and mix them up in a jar and let the sand settle. Then take bits of
    sediment
    from various layers and see if the pollens separated from one another?

    Even if this type of sorting could be explained, one has to wonder why
    the
    pollen of flowering plants which is microscopic happen to start showing
    up in
    the fossil record about the same time flowering plants if the fossil
    record is
    simply the result of plants and animals being trapped in the raging
    flood
    waters. One other observation along the same lines, it seems an amazing
    coincidence that the same plant is found to be the oldest flowering
    plant found
    in China and Germany on opposite ends of the world. How could the flood
    waters
    sort this particular plant which certainly wouldn't be the heaviest or
    lightest
    or anything unusual, from all other plants to place it at the lowest
    point of
    all flowering plants in two places of the world?

    To me the pollen and flowering plant appearance where they are in the
    rocks has
    to be the result of a supernatural process IF we grant the
    presupposition of
    the creation scientists that a global flood is responsible for the
    majority of
    the geological column. To me this is as miraculous as Christ rising from
    the
    dead. Now I absolutely believe in a miraculous resurrection but do I
    think
    that pollen miraculously was placed in the fossil record? I don't know.
    Obviously nothing in the Bible directly reveals this but this miracle
    could be
    inferred from Scripture if it can be confidently inferred that the
    entire
    geological column was formed after the creation week in a 6000 year old
    world.
    Here is just another case where I think the creation scientists trying
    to force
    a naturalistic explanation just doesn't work but I can see why many
    would also
    be uncomfortable simply positing everything as a miracle as well.

    Wish I had a great summary and big point to make but I don't so I'll
    just say,
    thanks is you managed to read this far down these ramblings from the
    McDonald's
    in Evansville Wisconsin. My fries are gone so it must be time to hit the
    road
    again. Regards, Joel
