Budňanská skála, Geological formation near Karlštejn, Czech Republic
The rock exposure spans across the southern slopes of Javorka, featuring natural layers of limestone and shale that reveal marine sedimentary structures.
During the 24th International Geological Congress in Montreal in 1972, scientists designated this site as an auxiliary international stratotype for the Silurian-Devonian boundary.
The location has attracted Czech geologists since the 19th century, with researchers documenting extensive collections of marine fossils and conducting detailed stratigraphic studies.
Visitors can access the formation from the road between Karlštejn and Srbsko, with collection of samples limited to fallen debris along the roadside.
The rock layers contain fossilized remains of ancient marine life, including large lily cup specimens from the genus Scyphocrinites, along with cephalopods and bivalves.
