Dinosaur Genera List corrections #147
Jack McIntosh called about an interesting new dinosaur just published in the C
omptes Rendus of the Academy of Sciences 330: 875-882, Paris (I'll have the
complete citation when the paper arrives in a few days). It's a Late
Maastrichtian lambeosaurine(!) from the Yuliangze Formation of China (don't
yet know where in China this is), and the holotype is a partial skull.
Most--but not all--of the crest is broken off, but what remains resembles the
crest of Parasaurolophus. Besides the holotype skull there is plentiful
disarticulated postcranial material from a bone bed, and a Parasaurolophus-lik
e skeletal reconstruction appears in the paper. This is the first good
lambeosaurine skull to come out of Asia, as far as I can recall.
Here's the name:
Charonosaurus Godefroit, Zan & Jin, 2000
C. jiayinensis Godefroit, Zan & Jin, 2000â
The genus has been added to the Dinosaur Genera List as genus #891, and the
species has been added to the Asian species section of the forthcoming second
printing of Mesozoic Meanderings #3.
In a cladogram in the paper, Charonosaurus appears as the sister group to Para
saurolophus, and these two genera together form a sister group to a clade
comprising Corythosaurus, Hypacrosaurus, and Lambeosaurus. This larger group
is sister to the other hadrosaurines, and so forth.
Miscellaneous correction: One of the authors of the Nanyangosaurus paper from
the previous DGL correction is Lu with an umlaut over the u. This may not
have transmitted correctly to everyone. Lu-umlaut is, I believe, one of the
authors of the Chuanjiesaurus paper, and I have corrected his name with that
genus in the Dinosaur Genera List from simply Lu.
