Dinosaur Genera List corrections #177



The dinosaur deluge of 2001 continues!

The following email concerning three new dinosaur papers in the latest issue 
of Vertebrata PalAsiatica, slightly edited, arrived from Kazuo Takahashi on 
November 15:

NEW MATERIAL OF MAMENCHISAURUS HOCHUANENSIS FROM ZIGONG, SICHUAN
YE Yong, OUYANG Hui, FU Qian-Ming
VERTEBRATA PALASIATICA Vol.39 No.4 pp. 266-271
from Abstract
The new material shows that the posterior caudals are fused with each other 
and are expanded and cockscomb-shaped, which differ distinctly from the 
hammer-shaped tail of Shunosaurus and Omeisaurus.


A LONG-NECKED THERIZINOSAUROID DINOSAUR FROM THE UPPER CRETACEOUS IREN DABASU 
FORMATION OF NEI MONGOL, PEOPLE'S REPUBLIC OF CHINA
VERTEBRATA PALASIATICA Vol.39 No.4 pp. 282-290
ZHANG Xiao-Hong, XU Xing, Pual SERENO, KUANG Xue-Wen & TAN Li
Abstract
Two partial skeltons are described from the Upper Cretaceous Iren Dabasu 
formation of Nei Mongol that represent a new therizinosauroid theropod. 
Neimongosaurus yangi gen. et sp. nov. , is the first therizinosauroid to 
preserve most of the axial column and nearly all of the long bones of a 
single individual. Distinctive characteristics of the new species include 
anterior caudal vertebrae with a circular fossa under the transverse precess, 
radius with a prominent biceps tuberosity, proximal pedal phalanges with well 
developed heels, tibia with an extremely long fibular crest that is much 
longer than the half length of the tibia, lateral surface of preacetabular 
precess twisted to face dorsally, and caudal vertebrae with widely divergent 
prezygapophyses. Neimongosaurus displays a few characters that are not 
reported in other therizinosauroids but do occur in some advanced 
maniraptorians, such as highly pneumatized vertebra and derived sholder 
girdle. Particularly the elongated neck and shortened tail previde further 
evidence for a close relationship between therizinosauroids and 
oviraptorosaurs.


A NEW SAUROPOD DINOSAUR OF CRETACEOUS FROM JIANGSHAN, ZHEJIANG PROVINCE
TANG Feng, KANG Xi-Min, JIN Xing-Sheng, WEI Feng & WU Wei-Tang
VERTEBRATA PALASIATICA Vol.39 No.4 pp. 272-281

Summary
The specimen described herein represents a new genus and species 
Jiangshanosaurus lixianensis of sauropod referable to the Titanosauridae. The 
specimen was collected by Wei Feng, Wu Wei-Tang and Kang Xi-Min in Jiangshan, 
Zhjiang allegedly from the lower part of Jinhua formation in Albian (105Ma) 
horizon. The prezerved part is fairly complete. Compared to the sauropod 
skeletons in China and other nations from Late Jurassic and Cretaceous, the 
diagnosis of scapulocorcoid and vertebrae of the new genus is most similar to 
those of Titanosauridae, especially Alamosaurus.
 The new fossil is described as the Titanosauridae for the first time in
China, and prevides new material for studying the evolution and
distribution of Cretaceous Sauropoda, Titanosauridae in China.

Accordingly, we add genera #928 and 929 to the Dinosaur Genera List:

Jiangshanosaurus Tang, Kang, Jin, Wei & Wu, 2001
Neimongosaurus Zhang, Xu, Sereno, Kuang & Tan, 2001

And the following species entries will be added to the list of Asiatic 
dinosaurs in the second printing of Mesozoic Meanderings #3:

Jiangshanosaurus Tang, Kang, Jin, Wei & Wu, 2001
    J. lixianensis Tang, Kang, Jin, Wei & Wu, 2001â

Neimongosaurus Zhang, Xu, Sereno, Kuang & Tan, 2001
    N. yangi Zhang, Xu, Sereno, Kuang & Tan, 2001â

After having reviewed quite a few emails on the subject, I have decided upon 
nomen ex dissertatione ("name from dissertation") as the best Latinized 
notation for a name used in a dissertation that is publicly available from an 
agency such as University Microfilms International. As I realized from the 
outset, nomen dissertatio is not the best notation, and I have changed it 
everywhere in the Dinosaur Genera List. I will also add nomen ex dissertatione
 to the notations in Mesozoic Meanderings #3.

I should also note the name

Jobaria tenerensis J. A. Wilson, 2000 [nomen ex dissertatione] will be added 
as a synonym of Jobaria tiguidensis in Mesozoic Meanderings #3 second 
printing. I recently purchased a copy of Jeff Wilson's 1999 dissertation from 
UMI, and this is what he called it there.
