Zuoyun Formation (Shanxi)

The Zuoyun Formation is an Early Cretaceous (estimated Albian) [1] geologic formation in Shanxi Province, China. [2] Dinosaur fossils attributable to the genus level are known from this formation. [1] During the Early Cretaceous, the Zuoyun area was generally dominated by an arid subtropical environment. There was irregular alternation of arid and humid climate, during which catastrophic flooding resulted in thick proluvial fan conglomerate-mudstone deposits. [3]

<i>Micropachycephalosaurus</i> Extinct genus of dinosaurs

Micropachycephalosaurus is an extinct genus of basal marginocephalian dinosaur containing only the type species, Micropachycephalosaurus hongtuyanensis. It lived in China during the Late Cretaceous (Campanian) and was found in the Jiangjunding Formation.

<i>Tianzhenosaurus</i> Extinct genus of dinosaurs

Tianzhenosaurus is a monospecific genus of ankylosaurid dinosaur from the Shanxi Province that lived during the Late Cretaceous in what is now the Huiquanpu Formation. Tianzhenosaurus may represent a junior synonym of Saichania, an ankylosaurine known from the Barun Goyot and Nemegt Formation.

<span class="mw-page-title-main">Stegosauria</span> Extinct clade of dinosaurs

Stegosauria is a group of herbivorous ornithischian dinosaurs that lived during the Jurassic and early Cretaceous periods. Stegosaurian fossils have been found mostly in the Northern Hemisphere, predominantly in what is now North America, Europe, Africa, South America and Asia. Their geographical origins are unclear; the earliest unequivocal stegosaurian, Bashanosaurus primitivus, was found in the Bathonian Shaximiao Formation of China.

Shanxia is a monospecific genus of ankylosaurid dinosaur from the Shanxi Province that lived during the Late Cretaceous in what is now the Huiquanpu Formation. Shanxia may possibly represent a junior synonym of Tianzhenosaurus, an ankylosaurine also known from the Huiquanpu Formation of China.

Jiutaisaurus is a genus of sauropod dinosaur from the Quantou Formation of Jilin, China. Jiutaisaurus was a sauropod which lived during the Cretaceous. The type species, Jiutaisaurus xidiensis, was described by Wu et al. in 2006, and is based on eighteen vertebrae. It probably lived alongside Changchunsaurus and Helioceratops.

The Xīnmínbǎo Group is a group of geological formations in north central China. They occur across a large depression between the Altai Mountains of Mongolia to the north and the Qilian mountains of the Qinghai Plateau to the south, in the Gōngpóquán (公婆泉) and Suànjǐngzi (算井子) basins, and also in the neighbouring Jiuquan Basin.

The Tuchengzi Formation is a geological formation in China whose strata span the Tithonian to Berriasian ages. Dinosaur fossils, particularly footprints, have been found from the formation.

The Huiquanpu Formation is a geological formation in Shanxi and Hebei provinces, China, whose strata date back to the Late Cretaceous period. It predominantly consists of purple-red mudstone, with subordinate grey-white sandy conglomerates.

<i>Yunganglong</i> Genus of dinosaurs

Yunganglong is an extinct genus of basal hadrosauroid dinosaur known from the early Late Cretaceous lower Zhumapu Formation of Zuoyun County, Shanxi Province of northeastern China. It contains a single species, Yunganglong datongensis.

The Zhumapu Formation is an early Late Cretaceous geologic formation in Shanxi Province, China. The hadrosauroids Yunganglong and Zuoyunlong and the informally named ankylosaur "Jindipelta" have been recovered from this unit.

<i>Zuoyunlong</i> Extinct genus of dinosaurs

Zuoyunlong is an extinct genus of herbivorous ornithischian dinosaur belonging to the Hadrosauroidea, that lived during the Late Cretaceous in the area of present China.

<i>Mongolostegus</i> Extinct genus of dinosaurs

Mongolostegus is a genus of stegosaur from the Early Cretaceous (Aptian-Albian) Dzunbain Formation of Mongolia. The type and only species is M. exspectabilis, known from a single specimen previously under the nomen nudumWuerhosaurus mongoliensis.

Jinbeisaurus is a genus of tyrannosauroid dinosaur from the Upper Cretaceous Huiquanpu Formation from Shanxi Province in China. The type and only species is Jinbeisaurus wangi. It is the first non-avian theropod known from Shanxi. Analysis of the specimen indicates that Jinbeisaurus is more derived than related tyrannosauroids such as Xiongguanlong and phylogenetically more advanced than Suskityrannus, to which it has been compared.

<i>Bashanosaurus</i> Extinct genus of stegosaurian dinosaurs

Bashanosaurus is an extinct genus of stegosaurian dinosaur from the Middle Jurassic Shaximiao Formation of Yunyang County, China. The genus contains a single species, Bashanosaurus primitivus, known from incomplete skeletons belonging to three individuals. It is one of the basalmost stegosaurs, as well as one of the oldest known stegosaurs, along with Adratiklit, Isaberrysaura, and Thyreosaurus.

<i>Yanbeilong</i> Genus of stegosaurian dinosaurs

Yanbeilong is an extinct genus of stegosaurian dinosaur from the Early Cretaceous (Albian) Zuoyun Formation of Shanxi, China. The type and only species is Y. ultimus. It is considered one of the youngest definitive records of the group, alongside Mongolostegus from Mongolia and possible Stegosaurus remains from the Hekou Group of China, both of which date to the Aptian–Albian.
