Stratigraphic resolution:group of beds
Stratigraphy comments: Godefroit et al. (2012): "Udurchukan Formation (Wodehouseia spinata - Aquilapollenites subtilis palynozone), ?Late Maastrichtian, Late Cretaceous"
Lithology and environment
Primary lithology:gray,green sandy,conglomeratic claystone
Includes fossils?Y
Lithology description: "grayish green clays with gravel inclusions...The bone beds are mixtites by genesis." "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"
Environment:fluvial indet.
