Salt Lake in Botswana (IMAGE)
Caption
Hypothetically speaking, large areas of the hyper saline Zechstein Sea and its direct environment could have looked like this, which in the Permian Age was situated about where present day Central Europe is. At the end of the Permian Age the Zechstein Sea was irrevocably disconnected from the open sea and the remaining sections of sea soon dried out after that. As a result the microbial-limited halogenated gases from the Zechstein Sea stopped and vegetation was able to regenerate again. The pink colour of the Zechstein Sea was probably brought about by microbes with an extreme preference for salt, as is the case with salt lakes today. In the background sand dunes can be recognized from a landscape with hardly any water.
