Zadni Treban, Pernik Beds, Kraluv Dvur Fm. (Ordovician of Czech Republic)

Where: Czech Republic (49.9° N, 14.2° E: paleocoordinates 60.2° S, 74.4° E)

• coordinate estimated from map

When: Proboscisambon trilobite zone, Kraluv Dvur Formation, Kralodvorian (449.5 - 445.6 Ma)

• "uppermost part of Kraluv Dvur Fm., Pernik Beds", in Owens (2004)

• group of beds-level stratigraphic resolution

Environment/lithology: offshore shelf; calcareous claystone

• The bed is currently interpreted as the results of climatic and glacioeustatic changes around the Katian/Hirnantian boundary, followed by Hirnantian glaciomarine deposits
• The ‘Perník bed’ is a richly fossiliferous carbonatic claystone forming the top part of the Králův Dvůr Formation (Štorch and Mergl 1989; see pl. 1, p. 128).

Size classes: macrofossils, mesofossils
