Living conditions at the time of the deposit of the Koessen formation

The landscape and the underwater world of 200 millions years ago was similar to what you can see today in Hurghada on the Red Sea or in Thailand and on Bali. The location of this small reef 1,880 m above sea level, and 2,000 km north of today’s most northern reef is impressive proof of the impermanence of the Earth’s crust, and the shifting distribution of the continents and oceans.
