Mikulov, Czech Republic — We have been very fortunate with the weather on our long IBA field excursion. Dazzling sunlit days and relatively cool evenings. Above is our first stop of the day — the Sandberg site with Miocene fossils in a loosely-bound sand.
Some of the Jurassic carbonates are exposed as boulders that tumbled down the slopes. This boulder has a surface that was exposed to the Miocene ocean and accumulated round bivalve borings (ichnogenus Gastrochaenolites, which has been seen a lot in this blog).
Another castle! This one very dramatic in its position commanding the confluence of the Morava and Danube rivers. It is the Devin Castle, which was destroyed by Napoleon himself in 1809.
River confluences are so cool. The Morava on the right is joining the Danube.
At this important confluence, at the border between what was Czechoslovakia and Austria during the Cold War, is a moving memorial to the over 400 people shot while trying to escape through the Iron Curtain.
The last stop of the day was the type section of the Hartl Formation (Middle Miocene, Badenian) near Eisenstadt, Austria. It is another loose sand, this time with common brachiopods and some bryozoans. This section is eroded back, forming a cave. The roof will collapse some day.
Tonight we stay in the historic Czech city of Mikulov on the border with Austria.
