Apparently, the 40 or 50 [depending upon source] million year old mummified wood found on Axel Heiberg Island still “contains all its organic matter”, “can still be burned” and is “so well preserved that it is difficult to distinguish from present-day samples”.
The eastern part is hilly, with local plains.
It was on this side of the island that large tree stumps were discovered in 1985.
The stumps have since been dated at 40 million years old, evidence that the Far North was at that time much warmer and wetter.
This “Fossil Forest” is not petrified but contains all its organic matter, making it a unique glimpse into an ancient ecosystem.
The stumps, logs, seeds, cones and leaves are in some cases so well preserved that it is difficult to distinguish them from present-day samples.
