Polystrate Trees

Polystrate Trees. Crossing several rock strata are trees preserved as well at their tops as at their bottoms. These fossil trees bridge an evolutionary imagined time span of millions of years, that would preclude their “in place” growth and fossilisation.

Question: Was this tree standing unweathered for millions of years while strata was slowly deposited all around it?

Answer: No! The sediment and tree were moved into place at the same time. Slow deposition of rock (uniformity)would not allow a tree to be fossilised before it would rot and fall over.
