Where: Czech Republic (50.0° N, 17.8° E: paleocoordinates 52.6° S, 62.0° E)
• coordinate based on political unit
• outcrop-level geographic resolution
When: Motol Formation, Homerian (430.5 - 427.4 Ma)
• Stage and zone not given. Inference of Homerian stage based on statement that this is stratigraphically above previous level (Homerian), section as a whole is said to be no younger than Homerian, and no faulting is mentioned (but faulting is explicitly mentioned elsewhere in description of this section in cases where older strata overlie younger strata).
• group of beds-level stratigraphic resolution
Environment/lithology: marine; volcaniclastic shale and green limestone
