West Quarry, Mokra, Czech Rep., collection from quadrat I3, bed 0 (Devonian of Czech Republic)

Where: Moravia, Czech Republic (49.2° N, 16.8° E: paleocoordinates 20.9° S, 29.4° E)

• coordinate based on political unit

• small collection-level geographic resolution

When: Macocha Formation, Frasnian (382.7 - 372.2 Ma)

• This is quadrant 3, from bed 0 and stratigraphic interval I.

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; intraclastic, shelly/skeletal wackestone

• 'shallow carbonate ramp with abundant reef dwelling fauna...have the character of reef banks.' 'northern margin of Devonian back-arc or related basins'
• 'biomicritic limestone with transitions into biointramicrite with fine horizontal bedding. At the base, there is a thin biosparite layer, in the upward direction micrite prevails. In the uppermost part, the rock passes into biosparite.'

Size classes: mesofossils, microfossils

Collection methods: '4 meter squared quadrants were reconstructed from paleo-sea floor fragments.'
