Abstract: Here we describe a number of mostly isolated bird and non-avian
dinosaur footprints from the Huangyangquan track site in the Lower Cretaceous
Lower Layer of the Tugulu Group near Huangyangquan Reservoir in the Wuerhe
District, Xinjiang Uyghur Autonomous Region, China. Bird footprints at the site
pertain to Koreanaornis dodsoni n. ichnosp.,
Goseongornipes isp., Aquatilavipes isp., and Moguiornipes
robusta n. ichnogen. n. ichnosp. Moguiornipes tracks may be
the products of a bird with lobed feet. These shorebird-morph tracks are the
first solid evidence of birds in the Tugulu Group, and greatly enrich the known
faunal diversity of the Lower Layer of the Tugulu Group. The Huangyangquan avian
ichnofauna is comparable to those of the Jindong Formation, Korea and the Dakota
Formation, USA. Non-avian dinosaur footprints at the site pertain to cf.
Jialingpus isp., Asianopodus isp., and Kayentapus isp. This is the first report
of Jialingpus from Lower Cretaceous strata. The discoveries of Asianopodus isp.
and Kayentapus isp. increase the known ranges of these two ichnogenera.

Abstract: Three sauropod trackways comprise eight tracks that resemble
Brontopodus tracks have been found at the Morong track site in Changdu
Prefecture, Tibet, China. These wide- (or sub-wide)-gauge tracks suggest that
there was a large sauropod, possibly a member of Titanosauriformes, in Changdu
Prefecture during the Early-Middle Jurassic. The sauropod fauna from Changdu
Prefecture, Tibet not only has elements in common with the sauropod fauna from
the Sichuan Basin, but may include more diverse faunal components.

Abstract: Diverse dinosaur (theropod
and sauropod) tracks from the Nanguzhai track locality in Donghai County,
Jiangsu Province, China occur in the Lower Cretaceous Mengtuan Formation. The
locality is subdivided into four adjacent track sites at the same stratigraphic
level. The sites preserve at least three track types pertaining to theropods and
juvenile to adult sauropods. "Backfilled" theropod and sauropod tracks at
Nanguzhai site III are the products of appendage—sediment interactions where the
substrate was fluid and behaved plastically.

Abstract: Diverse non-avian dinosaur (sauropod and ornithopod) and bird
tracks occur in the Lower Cretaceous Yangjiazhuang Formation at the
Zhangzhuhewan village track site in Zhucheng Basin, Shandong Province, China.
Non-avian dinosaur tracks at this tracksite are heavily deformed, having been
registered in waterlogged sediment. Sauropod pes and manus impressions, made by
a slowly advancing track maker, are roughly equal in area. The ornithopod tracks
are of the generalized Iguanodon-hadrosaur morphotype. The bird tracks are
unlike other Mesozoic bird tracks from China, but are similar to the
shorebird-like ichnotaxon Jindongornipes. Of tracks previously reported from the
Laiyang Group, Laiyangpus is of uncertain affinity and its type specimen has
been lost, and Paragrallator is referable to Anchisauripus isp. The new tracks
described herein further increase the known dinosaur diversity in eastern
Shandong Province.

Abstract: Herein we describe a single trackway that pertain to
Menglongipus sinensis ichnogen. et ichnosp. nov. from the Nijiagou track
site in the Chicheng county, Hebei Province, China. The tracks occur in the
Tuchengzi Formation, which spans the Jurassic-Cretaceous boundary. The discovery
of M. sinensis indicates that deinonychosaurians occupied this area
prior to deposition of the Yixian Formation, from which the oldest
deinonychosaur body fossils in the region have been found. The body length (~65
cm) of the M. sinensis track maker is very similar to that estimated for basal
paravians. Additional details are provided about the type Velociraptorichnus
sichuanensis, and the association between dromaeopodid and other
theropod tracks is discussed.

Abstract: Herein we describe three trackways that pertain to
Hadrosauropodus nanxiongensis ichnosp. nov. from the Yangmeikeng
track site in the Nanxiong Basin, Guangdong Province, China. The tracks occur in
the Upper Cretaceous Zhutian Formation. The nearby Gushi track site preserves
trackways attributable to Hadrosauropodus isp. These represent the first
occurrences of hadrosaur footprints in China. These discoveries expand the known
distribution of hadrosaur tracks from North America to China, and provides
evidence for the existence of large hadrosaurs in the Cretaceous of the Nanxiong
Basin. Other previously-described, large, ostensible ornithopod track
occurrences in China are discussed: Sinoichnites is represented only by
an informal “plastotype,” Yangtzepus is attributable to a theropod, and
Iguanodonopus is considered a nomen nudum and its specimens attributable
to Iguanodontipus. New specimens of Jiayinosauropus allow some
redescription of the ichnotaxon, and the unnamed Neixiang footprint is
redescribed.

Abstract: Herein we describe three and one half footprints that pertain
to Grallator isp. from the Lower Cretaceous Yixian Formation, Sihetun,
Liaoning Province, China. This is the first description of dinosaur footprints
from the Yixian Formation. The tracks were left by at least three individual
track makers. It is estimated from the tracks that the body lengths of the track
makers were 1.51 m, which is the average length of known theropods from the
Yixian Formation. The feet of Caudipteryx and Sinosauropteryx were
reconstructed. The former was more similar than the latter to the Grallator
isp. track outlines. Feet capable of registering Grallator morphotype
tracks may therefore have been widely distributed in small-medium sized
theropods (other than dromaeosaurids and troodontids) from the Yixian Formation.

Abstract：Herein described are two footprints that belong to the
new ichnospecies Changpeipus pareschequier ichnosp. nov. from the Lower
Jurassic Lufeng Formation near Yaozhan village, Lufeng County, Yunnan Province,
China. This is the first discovery of dinosaur footprints in the Lufeng
Formation. The ichnogenus Changpeipus is revised after the re-study of
its type specimens. Specimen IVPP V2472 2a, a supposed manus print that is part
of the ichnogenoholotype of Changpeipus carbonicus, is re-studied
herein and assessed as a pes print of a juvenile individual of the
Changpeipus carbonicus track maker. Changpeipus luanpingeris is a
junior synonym of Changpeipus carbonicus. Changpeipus pareschequier
ichnosp. nov. resembles the ichnotaxon Kayentapus. Based on its characteristics,
the footprints were presumably made by a member of the Coelophysoidea from the
Lufeng Formation.

Abstract: The dinosaur footprints
from the Middle Cretaceous Jiaguan Formation of Qijiang County are described.
Some new ichnotaxa,Qijiangpus sinensis ichnogen. et ichnosp. nov. of
Ankylosauria, Wupus agilis ichnogen. et ichnosp. nov. of Theropoda,
Laoyingshanpus torridus ichnogen. et ichnosp. nov. and Caririchnium
lotus ichnosp. nov. of Ornithopoda are erected. Among them, Qijiangpus
sinensis ichnogen. et ichnosp. nov. is the first record trace fossil of
Ankylosauria from China. Caririchnium lotus ichnosp. nov.
provides the evidence of the ontogenic development of Hadrosauroidea.
