West Quarry, Mokra, Czech Rep., collection from quadrat II26, bed 20B (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: Vilemovice Member (Macocha Formation), Frasnian (382.7 - 372.2 Ma)

• This is quadrant 26, from bed 20B and stratigraphic interval IV.

•Conodonts indicating Famennian age are from fissure fills. The reef limestones are of Famennian age (Joachimski pers. comm 2004 and Babek et al. 2007)

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; fine-grained, phosphatic, argillaceous grainstone

• 'shallow carbonate ramp with abundant reef dwelling fauna...have the character of reef banks.' 'northern margin of Devonian back-arc or related basins'
• 'fine-grained biosparite with admixtured micrite and clay. Conodonts and a phosphatic crushed mass of more robust unidentified skeletons are widespread.'

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.
