I've a computer in pieces - so just an intermittent connection - I've consequently only skimmed this topic.

There weren't trees around to fossilise - not as we know them. They were ferns - and are known as tree ferns. They produced the coal deposits which underlie northern england. They look like trees, as fossils. Ancient people knew about them and we have speculated here previosly as to what their beliefs may have cartegorised them as. I've a broken axe head that has been chipped from a fossilised bit of tree fern, which is recorded, so it's nothing new. Just a different scale. An amber is technically a fossil too - we know that was made into beads.

Getting conventional archaeologists to accept anything different is a task for masochists, perhaps.
