Where: Amur, Russian Federation (49.1° N, 130.9° E: paleocoordinates 51.4° N, 117.7° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Wodehouseia spinata - Aquilapollenites subtilis pollen zone, Udurchukan Formation (Tsagayan Group), Late/Upper Maastrichtian (70.6 - 66.0 Ma)
• Godefroit et al. (2012): "Udurchukan Formation (Wodehouseia spinata - Aquilapollenites subtilis palynozone), ?Late Maastrichtian, Late Cretaceous"
• group of beds-level stratigraphic resolution
Environment/lithology: fluvial; gray, green, sandy, conglomeratic claystone
•"The fossil-bearing sediments consist of an olive-grey muddy matrix, with dispersed very coarse sand particles and pebbles < 2 cm, and can be described as a clast-poor diamictite (Fig. 9E). The clays are dominantly smectite with some illite and kaolinite. These strata have a pattern of brown-coloured joints, some of which have evolved to minor faults."

•Godefroit et al. (2012): "The greatest part of the dinosaur material from Kundur, including the fossils described in the present paper, are included within massive, unsorted strata representing the deposits of ancient sediment gravity flows that originated from the uplifted areas at the borders of the Zeya-Bureya Basin. These gravity flows assured the concentration of dinosaur bones and carcasses as well as their quick burial. Such taphonomic conditions allowed the preservation of sub-complete hadrosaurid skeletons unearthed at the Kundur site"
