Also known as Kolguyev Island; Pechora Basin

Where: Arkhangelsk, Russian Federation (69.3° N, 49.9° E: paleocoordinates 41.8° N, 25.7° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Charkabozh Formation, Olenekian (251.2 - 247.2 Ma)

• Lower Triassic, Charkabozhskaya Svita, usually correlated with the Induan or Lower Olenekian. Biostratigraphic data points to a Olenekian rather than to an Induan age (Novikov & Orlov, 1992).
