This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

An Entire Tree
It's a amazing what can turn up when resurfacing a road. A complete fossilised tree has been found on the Greek island of Lesbos (https://www.theguardian.com/world/2021/feb/25/unique-petrified-tree-up-to-20m-years-old-found-intact-in-lesbos). The 20 million year old fossil, is almost 20m long with all its roots, branches and leaves. The tree had been buried in ash after one of the many volcanic eruptions in this area. The most interesting thing about the fossil is that it is completely different from the species now dominating the island. This tree was clearly a species adapted to hotter climates.
