Also known as Blagoveshchensk

Where: Amur, Russian Federation (50.3° N, 127.5° E: paleocoordinates 52.0° N, 113.8° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Udurchukan Formation (Tsagayan Group), Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• Wodehousia spinata-Aquilapollenities subtilis palynozone; lower part of group, Unit 2 of formation

• "deposition in fluvial or alluvial palaeoenvironment", interpreted as debris flows
• "green-coloured claystones with a considerable amount of dispersed granules. A basal pebble lag with a maximum clast size of 20 cm occurs at the base of these sediments."; "green-to-brown massive claystones...The clays are dominantly smectite with some illite and kaolinite. No bioturbation or paleosol development beyond inceptisols...matrix-supported clasts..."
