West Quarry, Mokra, Czech Rep., collection from quadrat I7, bed 3 (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 7, from bed 3 and stratigraphic interval I.

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; shelly/skeletal, sandy grainstone and reef rocks

• 'shallow carbonate ramp with abundant reef dwelling fauna...have the character of reef banks.' 'northern margin of Devonian back-arc or related basins'
• 'biosparite mainly, with larger fragments of stromatoporoids and corals floating within. Certain parts are bound with algae and stromatoporoids. The insoluble residue shows an increased amount of isometric quartz grains, up to 0.5mm in diameter.'

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.
