The large theropod track (length 58 cm) here described, from Maastrichtian
deposits of the Nanxiong Basin, is best attributed to a tyrannosaurid,
probably an animal roughly the size of Qianzhousaurus, which is possibly
the trackmaker based on the current body-fossil record of the region.

Ambopteryx represents exciting confirmation that at least some
scansoriopterygids were equipped with a membranous type of wing otherwise
unknown among dinosaurs, and throws new light on the anatomy and even the
digestive physiology of this most enigmatic, distinctive and short-lived
group of theropods.

The record of land tetrapods of the Cerro del Pueblo Formation (Late
Cretaceous, Campanian), in Coahuila, includes turtles, pterosaurs,
dinosaurs, and crocodyliforms. This last group is represented only by
goniopholidids, indeterminate eusuchians, and Brachychampsa montana. In
this work we report the first crocodyliform remains from La Parrita
locality,Cerro del Pueblo Formation, based on one isolated tooth,
vertebrae, and osteoderms. The association of crocodyliforms, turtles,
dinosaurs, and charophyte oogonia provide evidence for stagnant to fluvial
environments on a delta plain with tropical climate for the Cerro del
Pueblo Formation during the Late Cretaceous.

Recently, a vertebrate assemblage of the Jehol Biota has been reported from
the Early Cretaceous Hengtongshan Formation of Xingling Town, Meihekou
City, Jilin Province, China. It is dominated by the fishes Lycoptera and
Sinamia and the sinemydid turtle Ordosemys. Here, we describe the turtle
specimens and referral to Ordosemys liaoxiensis, otherwise known from the
older Yixian Formation of the Jehol Biota. It is characterized by a
subcircular shell, wide vertebral scales, well-developed plastral
fenestrae, and a major contribution from the xiphiplastra to enclose the
hypo-xiphiplastral fenestra. As the first Mesozoic turtle of Jilin
Province, this record represents the first tetrapod to indicate the
presence of the Jehol Biota in the region. Given the geographic and
temporal distance from the Yixian Formation, future collections from the
Hengtongshan Formation have good potential for evaluating spatiotemporal
patterns of the Jehol Biota.

Through the 1:50000 regional geological survey, a new nothosaur fossil site
was discovered in Guojiawan area, southwestern Guizhou Province. Based on
the field section measurement,the short-distance burial characteristics of
the fossils were analyzed in detail,and the age was considered to be Middle
Triassic Anisian Stage according to the regional geological mapping and
fossil data. Combined with the distribution and the paleogeographic
characteristics of the Anisian Stage biotas in the west of Guizhou Province
and its adjacent areas, the authors analyzed the possible source. The
result shows that Guojiawan area was the possible living place of the
nothosaur. The discovery of the nothosaur and its age provides new material
and evidence for the evolution and migration of Triassic Marine reptiles,
and hence has important scientific significance.
