Mokrá-Western Quarry
Basic information
Sample name: Mokrá-Western Quarry
Reference: M. Ivanov, A. Cernansky, I. Bonilla-Salomon, and A. H. Lujon. 2020. Early Miocene squamate assemblage from the Mokrá-Western Quarry (Czech Republic) and its palaeobiogeographical and palaeoenvironmental implications. Geodiversitas 42(20):343-376 [ER 4063]
Geography
Country: Czech Republic
Coordinate: 49.27° N, 16.73° E
Coordinate basis: estimated from map
Time interval: Early Miocene
Zone: MN4
Geography comments: "The Mokrá open-cast limestone mine is located about 12 km ENE of the city of Brno on the Mokrá Plateau in the southern part of the Drahany Upland (Moravia, Czech Republic)"
Environment
Lithology: claystone
Taphonomic context: fissure fill
Habitat comments: "Both karst fissures filled with unstratified non-calcareous sandy-clays were developed within the strongly karstified Vilémovice Limestone at the floor 380 m a.s.l. Osteological material was freely dispersed in the sediment"
Methods
Life forms: lizards,snakes
Sampling methods: screenwash
Sample size: 368 specimens
Sampling comments: "The sandy-clays from these two fissures (altogether 7.5 m3, about 13 tons) were first treated by H2O2 in aqueous solution with optimum concentration corresponding approximately to a 1 (H2O2 30 %):100 (H2O) ratio. After dissolving the clayey component, we washed sediments in sieves of 2 mm, 1 mm, and 0.5 mm mesh size."
