Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there. Many of the entries in this list are considered Lagerstätten (sedimentary deposits that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues).
Archaeocursor (meaning "old runner") is an extinct genus of basal ornithischian dinosaurs from the Early Jurassic Ziliujing Formation of China. The genus contains a single species, A. asiaticus, known from a single femur. Archaeocursor represents the oldest and most basal ornithischian described from Asia.
The Yanliao Biota comes from outcrops north of the Han Mountains, in the northeast of the People's Republic of China.The most important site is near Daohugou Village in Inner Mongolia, but fossils and outcrops are also found in neighbouring Liaoning Province and Heibei Province.
The Ziliujing Formation is a geological formation in China, It is Early Jurassic in age. It is part of the stratigraphy of the Sichuan Basin.The dinosaur Gongxianosaurus and indeterminate theropod material are known from the Dongyuemiao Member of the formation, as well as dinosaur footprints, Zizhongosaurus and indeterminate prosauropods from the Da'anzhai Member.

The Yixian Formation (simplified Chinese: 义县组; traditional Chinese: 義縣組; pinyin: Yìxiàn zǔ) is a geological formation in Jinzhou, Liaoning, People's Republic of China, that spans about 1.6 million years during the early Cretaceous period (Barremian-Aptian stage). It is known for its fossils, listed below.
Archaeamphora longicervia is a fossil plant species, the only member of the hypothetical genus Archaeamphora. Fossil material assigned to this taxon originates from the Yixian Formation of northeastern China , dated to the Early Cretaceous (around 143 to 101 million years ago ).
Some scientists have argued that the Jehol Biota evolved directly from the preceding Daohugou Biota without any strongly defined division. However, the absolute dating of the Daohugou beds has been the subject of divergent opinion: in 2006, Wang et al. [3] found an overall similarity between the fossil animals found in the Daohugou Beds and the "Jehol Biota" from the Yixian Formation.
The Shaximiao Formation (simplified Chinese: 沙溪庙组; traditional Chinese: 沙溪廟組 / 沙溪廟層; pinyin: Shāxīmiào zǔ) is a Middle to Late Jurassic aged geological formation in Sichuan, China, most notable for the wealth of dinosaurs fossils that have been excavated from its strata.
