Huiquanpu 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. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, Asia)."

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Datonglong Tianzhenensis
''Datonglong tianzhenensis'' is an herbivorous ornithischian dinosaur belonging to the Hadrosauroidea, which lived in the Late Cretaceous period in present-day China. It is the type species of the genus ''Datonglong''. Discovery and naming In 2008, a team from the Shanxi Museum of Geological and Mineral Science and Technology in the Kangdailiang quarry in Shanxi discovered the jaw of a Euornithopoda, euornithopod. In 2016, the species ''Datonglong tianzhenensis'' was named and described by Xu Shicha, You Hailu, Wang Jiawei, Wang Suozhu, Yi Jian, and Jia Lei. The generic name refers to the city of Datong and the Chinese word ''long'' (龍), which means “dragon”. The specific name refers to its origins in Tianzhen, Tianzhen county. ''Datonglong'' was one of eighteen dinosaur taxa from 2015 to be described in open access or free-to-read journals. Description The holotype, SXMG V 00005, consists of a portion of the lower jaw with some preserved teeth. The fossil was found in a ...
