Beipiaosaurus
''Beipiaosaurus'' is a genus of therizinosauroid theropod dinosaurs that lived in Asia during the Early Cretaceous in the Yixian Formation. The first remains were found in 1996 and formally described in 1999. Before the discovery of '' Yutyrannus'', they were among the heaviest dinosaurs known from direct evidence to be feathered. ''Beipiaosaurus'' is known from three reported specimens preserving numerous impressions of feather structures that allowed to determine the feathering color which turned out to be brownish. They were relatively small-sized therizinosaurs, measuring long and weighing about in contrast to the advanced and giant ''Segnosaurus'' or ''Therizinosaurus''. The necks of ''Beipiaosaurus'' were shorter than in most therizinosaurs, whose are characterized by elongated necks adapted for high-browsing. Also, their feet configuration differs from therizinosaurids, having a generic three-toed pes instead of four as seen in other members. The exact classification ...

Therizinosauroidea
Therizinosaurs (once called segnosaurs) were large herbivorous theropod dinosaurs whose fossils have been found across the Early to Late Cretaceous deposits in Asia and North America. Various features of the forelimbs, skull and pelvis unite these finds as both theropods and maniraptorans, close relatives to birds. The name of the representative genus, '' Therizinosaurus'', is derived from the Greek (, 'to reap' or 'scythe')Translated paper and (, 'lizard'). The older representative, ''Segnosaurus'', is derived from the ('slow') and the Greek . History of research [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Segnosaurus
''Segnosaurus'' is a genus of therizinosaurid dinosaur that lived in what is now southeastern Mongolia during the Late Cretaceous, about 102–86 million years ago. Multiple incomplete but well-preserved specimens were discovered in the Gobi Desert in the 1970s, and in 1979 the genus and species ''Segnosaurus galbinensis'' were named. The generic name ''Segnosaurus'' means "slow lizard" and the specific name ''galbinensis'' refers to the Galbin region. The known material of this dinosaur includes the lower jaw, neck and tail vertebrae, the pelvis, shoulder girdle, and limb bones. Parts of the specimens have gone missing or become damaged since they were collected. ''Segnosaurus'' was a large-bodied therizinosaur that is estimated to have been about long and to have weighed about . It would have been bipedal, with the trunk of its body tilted upwards. The head was small with a beak at the tip of the jaws, and the neck was long and slender. The lower jaw was down-turned at t ...

Therizinosaurus
''Therizinosaurus'' (; meaning 'scythe lizard') is a genus of very large therizinosaurid that lived in Asia during the Late Cretaceous period in what is now the Nemegt Formation around 70 million years ago. It contains a single species, ''Therizinosaurus cheloniformis''. The first remains of ''Therizinosaurus'' were found in 1948 by a Mongolian field expedition at the Gobi Desert and later described by Evgeny Maleev in 1954. The genus is only known from a few bones, including gigantic manual unguals (claw bones), from which it gets its name, and additional findings comprising fore and hindlimb elements that have been discovered during the 1960s–1980s. ''Therizinosaurus'' was a colossal therizinosaurid that could grow up to long and tall, and weigh possibly over . Like other therizinosaurids, it would have been a slow-moving, long-necked, high browser equipped with a rhamphotheca (horny beak) and a wide torso for food processing. Its forelimbs were particularly robust and had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xu Xing (paleontologist)
Xu Xing (; born July 1969) is a Chinese paleontologist who has named more dinosaurs than any other living paleontologist. Such dinosaurs include the Jurassic ceratopsian '' Yinlong'', the Jurassic tyrannosauroid ''Guanlong'', the large oviraptorosaur ''Gigantoraptor'', and the troodontid ''Mei''. Biography Xing was born in Xinjiang, China, in 1969. A graduate from the department of geology of Peking University, he is currently a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences in Beijing. He had originally planned to become an economist. However, he was assigned to the department of geology by the Chinese authorities. He graduated in 1995, and claims inspiration from Roy Chapman Andrews Roy Chapman Andrews (January 26, 1884 – March 11, 1960) was an American explorer, adventurer and naturalist who became the director of the American Museum of Natural History.

Yutyrannus
''Yutyrannus'' (meaning "feathered tyrant") is a genus of proceratosaurid tyrannosauroid dinosaur which contains a single known species, ''Yutyrannus huali''. This species lived during the early Cretaceous period in what is now northeastern China. Three fossils of ''Yutyrannus huali'' —all found in the rock beds of Liaoning Province— are currently the largest-known carnivorous dinosaur specimens that preserve direct evidence of feathers. Discovery and naming ''Yutyrannus huali'' was named and scientifically described in 2012 by Xu Xing ''et al.'' The name is derived from Mandarin Chinese ''yǔ'' (羽, "feather") and Latinised Greek ''tyrannos'' (τύραννος, "tyrant"), a reference to its classification as a feathered member of the Tyrannosauroidea. The specific name consists of the Mandarin ''huáli'' (华丽 simplified, 華麗 traditional, "beautiful"), in reference to the perceived beauty of the plumage. ''Yutyrannus'' is known from three nearly complete fossi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yixian Formation
The Yixian Formation (; formerly transcribed as Yihsien Formation) is a geological formation in Jinzhou, Liaoning, People's Republic of China, that spans the late Barremian and early Aptian stages of the Early Cretaceous. It is known for its exquisitely preserved fossils, and is mainly composed of basalts interspersed with siliciclastic sediments. History Japanese occupation The potential importance of the Yixian Formation was initially recognized during the time the Empire of Japan occupied China's Rehe ("Jehol") Province after the First battle of Hopei in 1933. Many Japanese scientists had noticed fossil remains of extinct fish and reptiles, possibly the champsosaurs. These initial fossil discoveries made by Japanese scientists vanished once World War II ended in 1945. Chinese rediscovery By 1949, when administration of the area passed to the Chinese Communist Party and its leader Mao Zedong, the fossils of Yixian were studied only by Chinese scientists. It was no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
