Sonidosaurus (meaning "Sonid lizard", after Sonid, the large geographical area that includes the type locality [1] ) is a genus of sauropod dinosaur from the Late Cretaceous. It was a titanosaur which lived in what is now Inner Mongolia. The type species, Sonidosaurus saihangaobiensis, was described by Xu, Zhang, Tan, Zhao, and Tan in 2006. It was a small titanosaur, about 9 meters (30 ft) long. [1] It was first discovered in the Iren Dabasu Formation in 2001 in a quarry which would later yield the remains of Gigantoraptor starting in 2005. [2]

Classification

In a 2017 review of Asian titanosaurs, Sonidosaurus was considered a lithostrotian titanosaur, with possible saltasaurid affinities. In particular, it shared with saltasaurids and the Bor Guve titanosaur a posterior centrodiapophyseal lamina on its dorsal vertebrae. [3]

Fusuisaurus is a genus of sauropod dinosaur from the Early Cretaceous of China. Fragmentary postcranial remains of this animal have been discovered in 2001 in the Napai Formation of Guangxi, China and consist of the left ilium, left pubis, anterior caudals, most of the dorsal ribs and distal end of the left femur. This sauropod has been described as a basal titanosauriform.

Saltasauridae is a family of armored herbivorous sauropods from the Upper Cretaceous. They are known from fossils found in South America, Africa, Asia, North America, and Europe. They are characterized by their vertebrae and feet, which are similar to those of Saltasaurus, the first of the group to be discovered and the source of the name. The last and largest of the group and only one found in North America, Alamosaurus, was thirty-four metres in length and one of the last sauropods to go extinct.

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

Gigantoraptor is a genus of large oviraptorosaur dinosaur that lived in Asia during the Late Cretaceous period. It is known from the Iren Dabasu Formation of Inner Mongolia, where the first remains were found in 2005.

The Iren Dabasu Formation is a Late Cretaceous geologic formation in the Iren Nor region of Inner Mongolia. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The formation was first described and defined by Henry Fairfield Osborn in 1922 and it is located in the Iren Nor region of China.

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 Bayin-Gobi Formation is a geological formation in Inner Mongolia, north China, whose strata date back to Albian of the Early Cretaceous period. Dinosaur remains are among the fossils that have been recovered from the formation.

Ruyangosaurus is a genus of titanosauriform sauropod dinosaur recovered from the Early Cretaceous Haoling Formation of China. The type species is R. giganteus, described in 2009 by Lü Junchang et al.

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

Baotianmansaurus is a genus of titanosaur sauropod dinosaur. Its fossils have been found in Upper Cretaceous rocks in Henan, China, within the Gaogou Formation. The type species is B. henanensis, described in 2009. The holotype is 41H III-0200. Remains of the fossils were vertebrae, ribs and scapula fragments. It was probably a close relative of Opisthocoelicaudia and Dongyangosaurus in Saltasauridae.

The Bayan Mandahu Formation is a geological unit of "redbeds" located near the village of Bayan Mandahu in Inner Mongolia and China and dates from the late Cretaceous Period. Laid down in the Campanian, it is dated somewhat uncertainly to between 75 and 71 mya.

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

Xianshanosaurus is a genus of sauropod dinosaur from the Early Cretaceous (Aptian-Albian) of the Ruyang Basin in Henan Province, China. Its type and only species is Xianshanosaurus shijiagouensis. It was described in 2009 by a team of paleontologists led by Lü Junchang. Xianshanosaurus may be a titanosaur, and Daxiatitan may be its closest relative, but its evolutionary relationships remain controversial.

The year 2011 in Archosaur paleontology was eventful. Archosaurs include the only living dinosaur group — birds — and the reptile crocodilians, plus all extinct dinosaurs, extinct crocodilian relatives, and pterosaurs. Archosaur palaeontology is the scientific study of those animals, especially as they existed before the Holocene Epoch began about 11,700 years ago. The year 2011 in paleontology included various significant developments regarding archosaurs.

Zhuchengtitan is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous of Shandong, China. It contains a single species, Z. zangjiazhuangensis, named by Mo Jinyou and colleagues in 2017 from a single humerus. Zhuchengtitan can be identified by the extreme width of the top end of its humerus, as well as the expansion of the deltopectoral crest on its humerus; both of these characteristics indicate that it was likely closely related to Opisthocoelicaudia. However, it differs from the latter by the flatter bottom articulating surface of its humerus. Zhuchengtitan lived in a floodplain environment alongside Shantungosaurus, Zhuchengtyrannus, and Sinoceratops.

Sinankylosaurus is a genus of dinosaur, originally described as an ankylosaur, from the Late Cretaceous Hongtuya Formation of Shandong, China. The genus contains a single species, Sinankylosaurus zhuchengensis, known from a nearly complete right ilium. The describers claim that the discovery of Sinankylosaurus further demonstrates the similarity between dinosaurs of eastern Asia and western North America.

Ruixinia is an extinct genus of somphospondylan titanosauriform dinosaur from the Early Cretaceous (Barremian) Yixian Formation of China. The genus contains a single species, Ruixinia zhangi. The Ruixinia holotype is a partial articulated skeleton with the most complete series of caudal vertebrae known from any Asian titanosauriform.
