   Sammanfattning : The only relatively undisturbed Ordovician to Middle Devonian sequence in the Bohemian Massif is preserved in the central parts of the Prague Basin. This part stretches c. 35 km from Prague in the north towards Zelkovice in the southwest. During Ordovician and Silurian times this area is thought to have been a part of the northern Gondwana margin. LÄS MER
