West Quarry, Mokra, Czech Rep., collection from quadrat IV25, bed 20A (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 25, from the upper part of bed 20A 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; pyritic, shelly/skeletal grainstone

• 'shallow carbonate ramp with abundant reef dwelling fauna...have the character of reef banks.' 'northern margin of Devonian back-arc or related basins'
• 'biosparite limestone, the insoluble residue contains a larger amount of pyrite framboides; sulfides and organic matter are often free from oxidation.'

Size classes: mesofossils, microfossils

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

• '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.
