Vinice Formation (Ordovician of Czech Republic)

Where: Prague, Czech Republic (50.0° N, 14.0° E: paleocoordinates 59.0° S, 79.5° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Vinice Formation, Berounian (457.9 - 449.8 Ma)

• Listed as Middle Berounian, BA4 Deanaspis-Aegiromena community

• group of beds-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, silty, sandy claystone

• The "bimodal" mixture of sand and shale may indicate proximity to shoreline, in which case this may be too shallow for inclusion, but presence of silt argues against this; "ill-aerated, soft-bottom environment below wave base". Oxygen levels reduced
• Claystones with a variable admixture of silt and sand

Size classes: macrofossils, mesofossils
