Sure, but apparently the chance that it survives 476K year is > 0. That would imply that the chance of finding preserved wood anywhere in [11K .. 476K] is > 0 as well.
Given such a large period with nothing found in it, and given that in this period wood needed to survive considerable less long than 476K, makes me want to look for other explanations.
