Does anyone know much about wood preservation in those kind of conditions; that is subzero conditions, I know the cold can preseve a lot of things, but wouldn't the timber suffer from possible dry rot?
It's a shame no one's answered your thread questions.
Actually because of Global Warming in both the Arctic and Antarctic almost perfectly preserved trees, stumps, forest floor liter (massive amount of it - branches, cones, leaves, needles, twigs, etc) and out right huge burried logs have been found. The wood is NOT fossilized, it's real and still burns with fire. One estimate in one valley on a Canadian island is that over 10,000 trees are buried there in the ground. The largest stump found was over three meters in diameter and the largest log was close to 28 meters long. This area is exactly 1,110 kilometers north of the arctic circle. In both Arctic and Antarctic finds, the reasons given for the extinction is a massive mega-sunami that wipe everything out and changed the climate permanently as we have it today. If you've ever seen photos of the Mt Saint Helens explosion which snapped massive trees like match sticks, then this mega-sunami is described as many times more powerful because it snapped off logs of every tree and buried instantly with mud and debri and flash froze them in time, much like the woolly mammoths who still had lilies and grasses in their mouths Mt. Saint Helens in Washington

[B]On the pic above, notice the two men at the bottom right hand corner to give an idea as to the scale. Undertand also that the trees snapped off like twigs in the arctic location were ancient redwood trees. Meta-Sequoia to be exact which were thought to be extinct because they had only been previously found in fossil areas of North Dakota and other regions, but found once again alive in China after WWII. This type of redwood is deciduous.

In fact in the Arctic islands near northern Greenland they even found an entire beaver dam preserved and the skeletal ramins of a beaver. The wood and large braches used in the beaver dam construction had all the characteristic edge markings of the beaver's teeth cuttings. They even found the remains of a crocodile in the buried pond.
What they can do are Oxygen isotope studies to reveal what the climate was like when these trees were living. So that supposedly old wood should reveal the same. But I'm skeptical of if the whole thing is true anyway. They said they dated the wood around 4,800 years old, but that's around the biblical dating of the deluge. The trees would have been old growth forest trees and at least a couple thousand years older than that. I believe they could if they really wanted to is take the wood to a reputable research lab, stay there with the experiments and testing to make sure no fraud takes place and have a verification from an outside source. But unfortunately with the distrust and bias on both sides, it's really hard to say if any real truth will come out of this in the end.
