Conchidium biloculare asiaticum Community, Early Ludlow, W Pribalkhash Region (Silurian of Kazakhstan)

Where: Kazakhstan (47.0° N, 75.0° E: paleocoordinates 7.9° S, 68.7° E)

• coordinate based on political unit

• basin-level geographic resolution

When: Ludlow (427.4 - 423.0 Ma)

Environment/lithology: marine; limestone

• "The brachiopods are most commonly disarticulated...indicating a high level of turbulence. This is a typical, maximum stage of development (climax stage), Late Silurian reef community."
• "Commonly occurs in massive, light colored, organogenic, brecciated limestone. "
