No, I am neither a geologist nor a botanist, I would be the first to say that my conclusions should be taken with a very great grain of salt. I would bow to Glenn's considerably greater expertise in this matter.
However, you gave us the URL so that we could look at this fossil ourselves and draw our own conclusions. I did exactly that and I'm afraid that I don't see what you imply is obvious. It could be that it's because it's a poor fossil, as Glenn seems to suggest. It could also be because it's not a true fossil at all, just an interpretation based on wishfull thinking. Even experts can be fooled -- have in fact been fooled -- if they believe something strongly enough.
If you wish to convince a non-expert such as myself that you have evidence that some theory is incorrect, you need to present evidence that is obvious even to that expert. This rock does not qualify and in fact only reinforces my feeling you have made a mistake.
