Ningxiapus, new ornithopod ichnogenus from China; Jehol biota lists (free pdfs in Chinese)



From: Ben Creisler

The new issue of the Chinese edition of Global Geology has been out
online for a few weeks. I finally found a version that can be
downloaded for free to get the English titles and abstracts.

Papers can be downloaded by clicking on underlined "PDF".

The pdfs are high resolution and download very slowly. Saving by
right-clicking and renaming seems to be slightly faster than
downloading by left-clicking.


In addition to the paper about Xinjiangtitan (already posted on the
DML a few weeks back with a link to Oliver Wings' website (the second
paper listed at the link above)), the issue has two other
dinosaur-related papers in Chinese:


FIRST PAPER LISTED:

ZONG Li-Yi,Lü Jun-Chang,WEN Wan-Cheng,YANG Qing & WAN Yang (2013)
Discovery of dinosaur footprints from Ningxia and its significance.
Global Geology (Chinese Edition) 32(3): 427-436

The first discovery of dinosaur footprints from Guyuan of Ningxia is
briefly reported. These dinosaur footprints include the ornithopod and
the sauropod dinosaur footprints. All of them are found in the Early
Cretaceous deposits of Liwaxia Formation. The ornithopod dinosaur
footprint is named as Ningxiapus liupanshanensis ichnogen. et
inchnosp. nov. It is characterized by the ratio of length to width 1.
22,the first toe slender,shorter than the fourth toe,the angle between
the second and the third toes 35°,and the angle between the third and
fourth 45° also. The sauropod dinosaur preserved their tracks also.
Their manus and footprints are 36 cm and 15 cm long respectively,
which implies that they were left by mid-sized sauropod dinosaurs. The
discovery of these footprints provides important information on
reconstruction of paleobiogeography and paleoecology,and the discovery
is very significant for searching of the dinosaur bones from this area
in the near future.

THIRD PAPER LISTED:

ZHANG Li-Jun (2013)
Main geological background during the evolution of Jehol Biota from
western Liaoning.
Global Geology (Chinese Edition) 32(3): 447-462
doi: 10. 3969 /j. issn. 1004-5589. 2013. 03. 003

Combining with the new data obtained from the fossils for recent
years, the author summarizes the distribution and composition of the
Jehol Biota from western Liaoning, makes clear on the evolutionary
sequences of the biota in several main basins, and analyzes the
evolution and geological background of the fossils vertebrates in
several main basins in this region. From the vertebrate evolution, the
author has recognized the radiation, convergence and complex evolution
in type. During the Yixian Formation stage,the specific formation
events were in existence due to the geographic isolation,and at the
Jiufotang Formation stage, the radiation of the pterosaurs and birds
is possibly related to the ecological isolation, which was mainly due
to the differentiation in feeding. The evolution of the Jehol Biota is
probably as a results of a cooperative action including indigenous
species outer immigrating, the alien species' invasion, the extinction
of some species after geographic isolation, and some population in
radiation, and complex evolution, which were all co-evolved in a
similar geological background. The volcanic rocks of the uppermost
Yixian Formation were passing the stratigraphic boundary with entering
the beginning of the Jiufotang Formation stage.
