|Dawn Redwood (Metasequoia glyptostroboides)|
Here are some of my pictures of the single specimen at the Göteborg Botanical Gardens. It was exciting when I found it there on my first visit ever to the Botanical Gardens. Prior to the visit I had been researching Metasequoia as a result of the uncovered giant trees found at the north pole on Axel Heiberg Island some couple decades back and the studies of not only the tree, but also what the climate was like to have such an incredible forest of these giants along with countless other biodiverse living organisms. There is a large stump field right where the trees actually grew after what was described by some as a mega-tsunami which destroyed life there by snapping the trees off their trunks and burying them under massive amounts of sediment which apparently flash froze. Sounds like a "The Day After Tomorrow" scenario of sorts doesn't it ? They estimate in an area called the Buchanon Lake Formation there are some 10,000+ logs and other debris buried there. But the truly amazing thing is that the evidence of this ancient world is still somewhat fresh. The wood still burns and so would the cones, leaves, twigs and branches they have unearthed as a result of further global warming revealing this treasure. None of this is petrified wood as in other fossils caches. Just extremely well preserved organic matter. I'll post a further references pages on this subject below.

The photo above insists that this is a 50-million-year old tree stump which lies exposed on Axel Heiberg Island, where Nunavut may establish a territorial park. I'm skeptical as to an actual 50 million years old without anything happening to cause decay. But the prevailing ideological philosophy holds the power of the print. Below is a photo of the stump field on the hillside. Notice the lake terracing effects of the gradual receding waters which were no doubt followed by snow and glacial build ups. One can only imagine how such an enormous extinction event not only wiped out all the rich biodiverse ancient life for good, but also entirely changing the weather dynamics permanently which presently prevents a re-occurrence of such life again.
