Oyster reef on building roads in Přímětice near Znojmo (Southern Moravia)

The paper describes the discovery of oyster reef which was uncovered during the construction of the ring road in Znojmo-Přímětice. A solid layer composed of oyster shells were found after the removal of quaternary sediments in the position above kaolinized granite. Fossils form 60 m long and 3–4 m wide belt. Thickness of the layer is up to 60 cm. Based on paleontological finds (Ostrea sp. and Crassostrea sp., Pirenella moravica Hörnes) layers were assigned to Eggenburgian age. We also received new informatik about the deposition of sediments and their deployment along the coast.
