Where: Russian Federation (60.0° N, 38.3° E: paleocoordinates 27.3° N, 34.8° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Roadian (272.3 - 268.8 Ma)
• Limestones ("calcaires marneux"), correlated with those at the base of the Permian system at Ustvaga. The correlation would suggest a Kungurian age (base of Murchison's Permian), but the fauna is more typical of the Kazanian.
• group of beds-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified, argillaceous limestone
Size class: macrofossils
