Dromaeosauripus is an ichnogenus that has been attributed to dromaeosaurs. [1] Dromaeosauripus footprints have been found at Dinosaur Ridge in the United States, Bito Island Tracksite in South Korea's Bito Island, and the Hekou Group in China. [2]
In 2012, D. yongjingensis was described from tracks in the Hekou Group. [2] D. yongjingensis shows prominent toe and heel pads. Heel pads are apparently absent in other Dromaeosauripus, probably due to behavior, preservation, and/or substrate consistency.
Huanghetitan, is a genus of sauropod dinosaur from the early Cretaceous Period. It was a basal titanosauriform which lived in what is now Gansu, China.
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 basal sauropod Sanpasaurus is known from the Maanshan Member. An unnamed stegosaur and the pliosauroid plesiosaur Sinopliosaurus are also known from this formation but they were found an indeterminate member. An unnamed teleosaurid known from a complete skull has also been found in the formation, pending a formal description. The deposition environment during the Da'anzhai Member in the lower Toarcian is thought to have been that of a giant freshwater lake encompassing the whole of the Sichuan basin, around 3 times larger than Lake Superior, coeval with the Toarcian Oceanic Anoxic Event around 183 Ma.
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 Tugulu Group is a geological Group in Xinjiang, China whose strata date back to the Early Cretaceous. Dinosaur skeletal remains and footprints are among the fossils that have been recovered from the formation.
Daxiatitan is a genus of sauropod dinosaur known from the Lower Cretaceous of Gansu, China. Its type and only species is Daxiatitan binglingi. It is known from a single partial skeleton consisting of most of the neck and back vertebrae, two tail vertebrae, a shoulder blade, and a thigh bone. At the time of its discovery in 2008, Daxiatitan was regarded as potentially the largest known dinosaur from China.
The Haman Formation is an Early Cretaceous geological formation in South Korea. It has been dated to the Albian, with an estimated maximum depositional age of 105.4 ± 0.4 Ma. The deposit is known for its tracks, including those of dinosaurs, pterosaurs and birds. It overlies the Silla Conglomerate which overlies the Chilgok Formation. It is laterally equivalent to the Sagog Formation.
The Hekou Group is a geological group in Gansu Province, China. It is Early Cretaceous in age. Many dinosaur fossils have been recovered from the Hekou Group, including iguanodonts, large sauropods, and armored dinosaurs. Fossil eggs are rare, but one oogenus, Polyclonoolithus, was discovered in the Hekou Group. Extensive fossil tracks belonging to pterosaurs and dinosaurs have also been described. The group spans the Valanginian to Albian and can be subdivided into four formations.
Xiongguanlong is an extinct genus of tyrannosauroid theropod from the Early Cretaceous period of what is now China. The type and only species is X. baimoensis. The generic name comes from Jiayuguan City and the Mandarin word "long" which means dragon. The specific epithet, "baimoensis" is a latinization of the Mandarin word for "white ghost" in reference to one of the geological features of the type locality.
Caririchnium is an ichnogenus of ornithopod dinosaur footprint, belonging to either derived iguanodonts or basal hadrosauroids. It includes the species Caririchnium lotus from Lower Cretaceous Jiaguan Formation and C. protohadrosaurichnos from Upper Cretaceous Woodbine Formation. Specimens are also known from the Lower Cretaceous El Castellar Formation and Camarillas Formations.
Deltapodus is an ichnogenus of footprint produced by a stegosaurian dinosaur According to the main Stegosauria article:
Yongjinglong is an extinct genus of titanosauriform sauropod dinosaur known from the Early Cretaceous of Lanzhou-Minhe Basin of Gansu Province, China. It contains a single species, Yongjinglong datangi.
The Jingchuan Formation is a Barremian geologic formation in China. Various dinosaur fossils and tracks have been reported from the formation.
The Hekou Formation is a Cretaceous geologic formation in China. Pterosaur fossils have been recovered from the formation. It is a unit of the Guifeng Group and dates to the Late Cretaceous. An unnamed large hadrosaurid is also known from the formation.
Polyclonoolithus is an oogenus of fossil dinosaur egg. It is from the Early Cretaceous of Gansu, China. They have distinctive, branching eggshell units, which may represent the original form of spheroolithids.
Xunmenglong is a genus of compsognathid theropod dinosaur from the Huajiying Formation from Hebei Province in China. The type and only species is Xunmenglong yinliangis. The holotype material consists of a pelvis, tail base and hindlimbs that had previously been part of a chimera containing three different animals. The animal is described as being the smallest known member of Compsognathidae, being about the size of the sub-adult Scipionyx holotype specimen or approximately 0.5 meters in length.
Jingmai Kathleen O'Connor is a paleontologist who works as a curator at the Field Museum.
The Shengjinkou Formation is an Early Cretaceous (Aptian)-aged Konservat-Lagerstätte composed of "interbedded red green and yellow variegated mudstones and siltstones" that is part of the larger Tugulu Group of China. Dinosaur and pterosaur remains have been recovered from the formation.
Datai is an extinct genus of ankylosaurid dinosaur from the Late Cretaceous Zhoutian Formation of Jiangxi Province, China. The genus contains a single species, D. yingliangis, which is known from the articulated skulls and partial skeletons of two individuals.
The Zhoutian Formation is a geological formation in Jiangxi, China. It has been dated to the late Cretaceous period, at about 96–90 Ma. Abundant egg fossils are known from the formation, in addition to dinosaurs such as Datai and Gandititan. Invertebrate and plant fossils have also been described from the Zhoutian Formation.
