Karakavak Fm, Kauk River, Alai Ridge, Kyrgystan (Devonian of Kyrgyzstan)

Where: Kyrgyzstan (39.6° N, 72.8° E: paleocoordinates 3.4° S, 74.5° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Karakavak Formation, Pragian (410.8 - 407.6 Ma)

• formation-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; lithified, silty, calcareous sandstone and lime mudstone
