Hadrosaurs from China and Russia + K/Pg boundary stuff in Global Geology



From: Ben Creisler

This recent issue of Global Geology apparently has not been mentioned on
the DML yet. It contains a series of articles about the K/Pg boundary in
northern China and Russia near the border region--it includes an article
about hadrosaurs.

Here's the full ref for the hadrosaur paper (no page numbers or doi for
now):

Recent advances on study of hadrosaurid dinosaurs in Heilongjiang (Amur)

Four main dinosaur-bearing sites have been investigated in latest
Cretaceous deposits from the Amur/Heilongjiang Region: Jiayin and Wulaga in
China (Yuliangze Formation),Blagoveschensk and Kundur in Russia (Udurchukan
Formation). More than 90% of the bones discovered in these localities
belong to hollowcrested lambeosaurine hadrosaurids: Charonosaurus
jiayinensis at Jiayin, Amurosaurus riabinini at Blagoveschensk, Olorotitan
arharensis at Kundur,and Sahaliyania elunchunorum at Wulaga. Flat-headed
hadrosaurine hadrosaurids are much less numerous,but appear well
diversified as well: Kerberosaurus manakini at Blagoveschensk, Wulagasaurus
dongi at Wulaga,and a new genus at Kundur. Theropods are represented by
shed teeth and isolated bones; isolated scutes and teeth discovered at
Kundur are tentatively attributed to nodosaurids. Palynological studies
suggest that these sites are probably synchronous with the Lancian
vertebrate localities of western North America,which represent the youngest
dinosaur faunas in this area. However,the latest Cretaceous dinosaur
assemblages are completely different in the Amur/Heilongjiang region
(lambeosaurines abundant,ceratopsids absent) and in western North America
(ceratopsids abundant,lambeosaurines extremely rare or absent). This
probably reflects some kind of geographical barrier between both areas by
Maastrichtian time rather than strong differences in palaeoecological
conditions.
