Dinosaur Genera List update #191

[Dinogeorge@aol.com]

Firstly, I forgot to note in DGL update #190 that Andy Heckert's new genera 
are both ornithischian.

A few days ago a book arrived here from Japanese correspondent from Masahiro 
Tanimoto:

Hu Chengzhi, Cheng Zhengwu, Pang Qiqing & Fang Xiaosi, 2002. Shantungosaurus 
giganteus: [3 front matter] + ii + 139 pp. + 18 plates [in Chinese with 
English abstract; publisher's name not translated: ISBN 7-116-03472-2].

Besides a lengthy and long-awaited osteology of the distinctive giant 
hadrosaurian Shantungosaurus giganteus, it also features the description of a 
new species of tyrannosaurid, Tyrannosaurus zhuchengensis. Material comprises 
a right metatarsal IV 531 mm long and (at least) three teeth found with the 
original Shantungosaurus material and referred to in the original description 
of Shantungosaurus by Hu (1973) as Tyrannosaurus cf. rex. Species name 
derives from Zhucheng County, Shandong Province. Catalogue numbers for these 
specimens are not provided. Because most of the short discussion involves the 
metatarsal, I presume that it's the holotype, and the teeth are referred or 
paratypes. I strongly doubt whether these specimens belong to the same 
individual.

This does not change the Dinosaur Genera List, but I will add the new species 
to the table of Asiatic dinosaurs in the forthcoming second printing of 
Mesozoic Meanderings #3. Not for a moment do I believe this material belongs 
to the genus Tyrannosaurus (a detailed comparison is not available in the 
abstract, but it might be in the Chinese part of the paper); I think it 
should have been referred to the Asiatic genus Tarbosaurus (or to my personal 
choice, Jenghizkhan, should it turn out after all that that genus is valid), 
although it is probably nondiagnostic at the generic level and almost 
certainly nondiagnostic at the species level. (Best would have been 
Tyrannosauridae incertae sedis, but now that we have a species, we need a 
genus to plug it into.) Referral to the North American genus Tyrannosaurus 
might be used to support an Asiatic origin for that genus and is not 
warranted due to the incompleteness of the material.

The book also adds to the literature on other Asiatic hadrosaurians, 
including Tanius sinensis, Tsintaosaurus spinorhinus, Bactrosaurus johnsoni, 
Gilmoreosaurus mongoliensis, Mandschurosaurus amurensis, Jaxartosaurus 
aralensis, and Nipponosaurus sachalinensis (as N. sachaliensis [sic]); eggs; 
and iguanodontians, psittacosaurians and protoceratopids.
