Why does everything have to be millions of years. The Mt. St Helens eruption changed the landscape in a day. Lakes were removed, rivers re routed and canyons were dug overnight.
Have you seen the iron hammer that was dug from a coal mine that was supposed to be millions of years old? How about the fossilized "foot" still in a cowboy boot manufactured in the 1950's that was dug out of a stream bed in Texas?
When people buy into this stuff, it just shows a lack of common sense. How many armadillo's remain on the side of the road long enough to be fossilized? It must happen quick to cut off the oxygen, and most likely the covering up is what killed them. If you find an animal that was obviously eaten, then the remains would have had to be covered within a short while after. Also, the covering would have to be several feet thick or made of something like clay or molten rock. Otherwise the organic material would still decay over a relatively short time.
The pictures show that the leaves retain a green color, which would be the result of chlorophyll, a green photosynthetic pigment found in most plants, algae, and cyanobacteria. How can a 300 million year old fossil, or even one a few thousand years old, retain that pigment unless it was somehow preserved almost instantaneously by some catastrophic event?
You are right, of course, but your thesis will never pass “peer review.”
