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."
