I never saw pictures of upside down trees but have seen standing trees fossilized. My only explanation is they got covered up quickly or the wood was really rot resistant LOL. It doesnt take that much covering to cover bones and I never said exactly how much covering is the perfect recipe.They could have been ;laying horizontally at first and then got heaved up by some catastrophic force.

Mount Saint Helen is proof that tree's can be fossilized it a short period of time.
Bud not necessarily from a flood.
In this case it was a volcanic eruption.

Were the trees upside down in several different layers of material?

We know

I don't believe so .
My guess its multy layers of polly straight trees would be a result of the Great flood.
Or Noah's flood as those believing in the Biblical story including myself know it as.

Speaking of petrified trees. Over 75,000 square miles of Washington, Oregon, and Idaho were flooded with many (hundreds) of very fluid lava flows in what is known as "the Columbia river basalt flows". These flows occurred between about 6 million and 17 million years ago. Sometimes the periods between flows was thousands and thousands of years. This allowed entire ecosystems to become established between the different flow periods.

Sandwiched between these flows are fossils of animals and plants that are distinctly different from each other. Some have animals that include animals like rhinoceros, however there are no dinosaur fossils, so these flows occurred after they became extinct.

One particular flow covered what had been a large rather swampy ecosystem, there were layers of ginkgo trees that got fossilized between two of these basalt lava flows. You can visit what is called the Ginkgo Petrified Forest, it's pretty interesting.

Geology is very complex, and there is no "one size fits all" answer to what we observe in all these different examples.

Interesting stuff.

very interesting

In the first picture you can see some of the different flows of Columbia river basalt. Some flows occurred in fairly rapid succession, and other flows occurred with thousands of years between the flows, which allowed different ecosystems to become established.
The second picture is of some petrified logs that were between one of the periods of lava flows.

There is unrefuted evidence of a great flood(s) coming across these basalt flows about 15,000 years ago. They are called the Bretz floods, or the Missoula floods. Some people believe this may have been the "Great Flood", possibly, however I think it was more localized, but who knows"? Regardless, it was rather recent in geological time, and definitely after the extinction of dinosaurs as is evidenced by the lack of dinosaur fossils between the various lava flows.
So, if you believe this was the "Great Flood", which it may have been. There were apparently no dinosaurs at the time of Noah.

I think you have a sample size problem with that conclusion. To infer the absence of fossilized dinosaurs on that one tiny area of earth, in those snapshots of time, proves there was no living dinosaurs left on earth is a huge overreach. I have no idea if there were living dinosaurs at the time of Noah. But that is not evidence one way or the other.

You are right, it's just one piece of the puzzle.
Like I said, there is no one size fits all answer to some of these questions.

Waggler, do you believe the scientists are correct when they claim dinosaurs went extinct at the end of the Cretaceous period..~65 million years ago according to them?

^^^^
Generally speaking yes, I'm not sure about the exact dates. However, they died out well before the flood.

One theory.

I believe the Bible, just run the numbers of men's ages in the genealogies and you get the age of the world. If you are interested in Creation and learning more about it, even if you don't believe in it, watch "Answers In Genesis" on YouTube.

^^^^^
Just curious if you have evervlistened to John Lennox on the subject.
