Actually, "expectatus" might be better than "inexpectatus". The Zhuceng fauna
(and other later Late Cretaceous assemblages from
northeastern Asia) is very, very much like typical western North American mesic
(wet) communities of the Campano-Maastrichtian
(Dinosaur Park Formation, Horseshoe Canyon Formation, etc.). There are more
taxa to come that show this as well.
It is important to remember that nearly every general paleogeographic is 100%
WRONG about the Bering Sea region, in creating a
non-existent separation between northeastern Asia and Alaska. Even today there
are no tectonic features separating these units, only
a very shallow ephemeral strait. Geologically--and paleogeographically--Siberia
and Alaska are the same place.
