The Houcheng Formation is a geological formation in Hebei, China whose strata date back to the Upper Middle Jurassic. The lithology primarily consists of sandstone and conglomerate deposited in fluvial, alluvial fan and fan delta conditions, with interbeds of volcanic rocks. [1] Dinosaur remains are among the fossils that have been recovered from the formation. [2]

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

Xuanhuaceratops is a genus of dinosaur from the Late Jurassic Period. The genus was in 2006 dated to the Tithonian, 150.8-145.5 million years ago. A member of the family Chaoyangsauridae, it was one of the earliest ceratopsians. The fossils were found in the Houcheng Formation of Hebei Province, northeastern China.

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

Szechuanosaurus is an extinct genus of carnivorous theropod dinosaur from the Late Jurassic. Fossils referred to the genus have been found in China, Asia in the Oxfordian-?Tithonian. Its type species is based on several undiagnostic teeth from the Kuangyuan Series. Additional possible specimens of Szechuanosaurus were also reported from the Kalaza Formation, also located in China.

Monkonosaurus is a dubious genus of herbivorous stegosaurian dinosaur from the Late Jurassic/Early Cretaceous-aged Loe-ein Formation of Tibet. Some sources place it as alive during the Oxfordian - Albian stages, around 163 - 100 million years ago, although Monkonosaurus was probably only alive during the Late Jurassic, making it among the earliest known stegosaurs along with Chungkingosaurus and Bashanosaurus.

<span class="mw-page-title-main">Chaoyangsauridae</span> Family of ceratopsian dinosaurs

Chaoyangsauridae is a family of ceratopsian dinosaurs. They are among the earliest known marginocephalian dinosaurs, with remains dating to about 160 million years ago, during the Late Jurassic period. Members of this group had sharp beaks for snipping off leaves to eat, and a very small frill.

The Lufeng Formation is a Lower Jurassic sedimentary rock formation found in Yunnan, China. It has two units: the lower Dull Purplish Beds/Shawan Member are of Hettangian age, and Dark Red Beds/Zhangjia'ao Member are of Sinemurian age. It is known for its fossils of early dinosaurs. The Dull Purplish Beds have yielded the possible therizinosaur Eshanosaurus, the possible theropod Lukousaurus, and the "prosauropods" "Gyposaurus" sinensis, Lufengosaurus, Jingshanosaurus, and Yunnanosaurus. Dinosaurs discovered in the Dark Red Beds include the theropod Sinosaurus triassicus, the "prosauropods" "Gyposaurus", Lufengosaurus, and Yunnanosaurus, indeterminate remains of sauropods, and the early armored dinosaurs Bienosaurus and Tatisaurus.

<span class="mw-page-title-main">Inferior Oolite</span>

The Inferior Oolite is a sequence of Jurassic age sedimentary rocks in Europe. It was deposited during the Middle Jurassic. The Inferior Oolite Group as more recently defined is a Jurassic lithostratigraphic group in southern and eastern England. It has been variously known in the past as the Under Oolite, the Inferior Oolite, the Inferior Oolite Series and the Redbourne Group.

The Chuanjie Formation, is a geological formation in Yunnan, China. It dates back to the Middle Jurassic. It was formerly referred to as being the lower member of the "Upper Lufeng" as opposed to the underlying "Lower Lufeng" now referred to as the Lufeng Formation. Tracks of theropods and sauropods, as well as thyreophorans are known from the formation.

The Penglaizhen Formation, is a geological formation in Sichuan, China. It was formerly thought to be Late Jurassic in age. However, the underlying Suining Formation has been dated to the Mid Cretaceous, so the formation must be this age or later However a subsequent study suggested that the dates for the formation had been altered by geologic processes, and there dating the Suining Formation to the around the Jurassic Cretaceous boundary about 145 Ma, which means that Penglaizhen Formation is likely Early Cretaceous in age. Dinosaur remains are among the fossils that have been recovered from the formation.

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 Shishugou Formation is a geological formation in Xinjiang, China.

The Kalaza Formation is a geological formation in Xinjiang, China whose strata date back to the Late Jurassic. There is some confusion with the stratigraphy of this unit, as the term is used for sediments of equivalent age in both the Junggar Basin and the Turpan Basin. Dinosaur remains are among the fossils that have been recovered from formation.

The Minhe Formation is a geological formation in northwestern China, whose strata date back to the Late Cretaceous period.

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.

The Xiaoyan Formation is a geological formation in Anhui, China whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. It overlies the older Qiyunshan Formation which it forms the Huangshan Basin with, and was deposited between the Campanian and Maastrichtian stages.

The Kugitang Formation or Group is an Oxfordian geologic formation in Tajikistan and Uzbekistan and a geologic group in Turkmenistan. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.

The Lianmuqin Formation, also transcribed as Lianmugin Formation, and Lianmuxin Formation, is an Early Cretaceous geologic formation composed of "interbedded red green and yellow variegated mudstones and siltstones". Dinosaur remains have been recovered from it.

The Toutunhe Formation is a Late Jurassic geological formation in China, specifically dating to the Oxfordian and Kimmeridgian stages. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The lower portion of the formation consists of grey to reddish mudstone with medium to coarse grained cross bedded sandstone, while the upper portion consists primarily of brown-red-purple mudstone, interbedded with fine to medium grained laminated sandstone.

The Kurek Formation is a late Oxfordian geologic formation of the Kugitang Svita in Turkmenistan and Uzbekistan. Fossil sauropod tracks have been reported from the formation.

The Zhenzhuchong Formation is an Early Jurassic geologic formation in China. Plesiosaur remains are among the fossils that have been recovered from its strata. Remains of the prosauropod Lufengosaurus huenei have been recovered from this formation As well as dinosaur footprints.

The Zhiluo Formation is a geological formation in China, it is also alternatively considered a geological group under the name Zhiluo Group. It dates to the Middle Jurassic. It consists of sandstone, mudstone and siltstone of varying colours. It has received scientific attention for its uranium ore bodies present in the lower part of the formation. Fossil theropod tracks have been reported from the formation. These were described from two footprints found in Jiaoping Coal Mine by C. C. Young in 1966 as Shensipus tungchuanensis. These were in 2015 suggested to belong to Anomoepus. The dinosaur Lingwulong has been suggested to have come from the strata of this formation, previously having been attributed to the underlying Yanan Formation.
