When: Wodehouseia spinata - Aquilapollenites subtilis pollen zone, Udurchukan Formation (Tsagayan Group), Late/Upper Maastrichtian (70.6 - 65.5 Ma)
• Godefroit et al. (2012): "Udurchukan Formation (Wodehouseia spinata - Aquilapollenites subtilis palynozone), ?Late Maastrichtian, Late Cretaceous"

Environment/lithology: fluvial; gray, green, conglomeratic claystone
•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"
