Moldotau Range, Karakichi River (Cambrian to of Kyrgyzstan)

Where: Kyrgyzstan (41.9° N, 74.7° E: paleocoordinates 1.8° S, 97.2° E)

• coordinate estimated from map

When: Karadzhorga Formation, Mayan to Mayan (504.5 - 485.4 Ma)

• In the Moldotau range, central Tien Shan, late Middle - early Cambrian lingulate brachipods are known currently only from a single fossil locality (127-9)

• bed-level stratigraphic resolution

Environment/lithology: marginal marine; siliciclastic sediments

• The Middle-Upper Cambrian deposits here are fine clastic sediments and tuffs of the Karadzhorga Formation, with a total thickness of about 150m. This formation sits on andesitic volcanic rocks and tuffs of the Karaarcha Formation and is overlain unconformably by Lower Carboniferous strata.

Size classes: macrofossils, mesofossils

Preservation: cast
