West Quarry, Mokra, Czech Rep., collection from quadrat II10 lower part of bed 5 (Devonian to of Czech Republic)

Where: Moravia, Czech Republic (49.2° N, 16.8° E: paleocoordinates 17.7° S, 25.3° E)

• coordinate based on political unit

• small collection-level geographic resolution

When: Macocha Formation, Frasnian to Frasnian (382.7 - 358.9 Ma)

• This is quadrant 10, from bed 5 and stratigraphic interval II.

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; framestone and claystone

• 'shallow carbonate ramp with abundant reef dwelling fauna...have the character of reef banks.' 'northern margin of Devonian back-arc or related basins'
• 'framestones built of complicated sheets of corals and, in parts, stromatoporoids. The intercoral spaces are filled with carbonate claystones or micritic limestones with Moravamminidae indet. and rarely Umbellina sp. Depressions at the top of the framestone layer are often filled with coquina of thin-walled smooth brachiopods (unidentified broken valves).'

Size classes: mesofossils, microfossils

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

Taxonomic list

• 'Abundance is the number of individuals for solitary organisms or the number of colonies for clonal organisms.' Paper also gives occupied area for each taxon, and estimates skeletal mass produced per year and biomass produced per year -- I have reported abundance values.
