Plateau

Plateau


This is a macro of the previous shroom. The cracking patterns reminded me of the geography lesson about continents drifting apart but used to be one whole large island called the pangea.



Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. For example, fossils of the therapsid Lystrosaurus have been found in Gandu, South Africa, India and Australia, alongside members of the Glossopteris flora, whose distribution would have ranged from the polar circle to the equator if the continents would have been in their present position; similarly, the freshwater reptile Mesosaurus has only been found in localized regions of the coasts of Brazil and West-Africa.[5]

Additional evidence for Pangaea is found in the geology of adjacent continents, including matching geological trends between the eastern coast of South America and the western coast of Africa.

Just passing through.

Beautiful shot! Very dramatic lighting too (though I suppose it's probably natural lighting).
