Beroun, Czech Republic — Today the International Bryozoology Association pre-conference field party visited a fascinating quarry near Chrtníky, Czech Republic. Ordovician diabase is mined here for road gravel and other industrial uses. This rock was uplifted and exposed during the Mesozoic. In the Late Cretaceous, the sea flooded into valleys excised into the diabase, creating long, narrow seaways with steep cliffs of diabase. Cretaceous marine marls filled the valleys, enclosing lots of fossils.
Earlier in the day we explored the Czech city of Olomouc, where we had spent the night. The statuary is magnificent, as seen here in the city square.
We can’t forget what a nightmare this city was, though, for its Jews during World War II. Olomouc was dominated by Germans before and during the war. Almost all the Olomouc Jews were deported to concentration camps, where most were killed. Small plaques like these are set among the cobblestones, marking the former homes of Jews and their deportation dates.
