Coralloidoolithus
''Coralloidoolithus'' is an oogenus of dinosaur egg from the Tiantai Basin in Zhejiang Province, containing a single known oospecies ''C. shizuiwanensis''. Formerly, it was classified in the oogenus '' Paraspheroolithus''; however, it was considered sufficiently different to be classified in its own genus. ''C. shizuiwanensis'' is similar to ''Stalicoolithus'', leading to their classification in the same family, Stalicoolithidae.Wang Q, Wang X L, Zhao Z K, and Jiang Y G. (2012).A new oofamily of dinosaur egg from the Upper Cretaceous of Tiantai Basin, Zhejiang Province, and its mechanism of eggshell formation Chinese Science Bulletin. 57: 3740-3747. doi: 10.1007/s11434-012-5353-2 History Xixia County was first excavated for fossils by a Geological Team of the Henan Geological Bureau in 1974. Fossils continued to be excavated there, but were not extensively studied until 1994 when Fang ''et al.'' received funding from the National Natural Science Foundation of China. Under this ...

Stalicoolithidae
Stalicoolithidae is an oofamily of fossil eggs.Wang Q, Wang X L, Zhao Z K, and Jiang Y G.

Jin, J.K. O'Conner, M. Wang, and J. Xie. (2015). "A new egg with avian egg shape from the Upper Cretaceous of Zhejiang Province, China." ''Historical Biology'' 27(5):595-602. or as Spheroolithids, in the case of ''"Paraspheroolithus" shizuiwanensis'' and '' Shixingoolithus''. Description Stalicoolithids are distinguished from other oofamilies by several characteristics. Most significantly, they have secondary eggshell units in the outer zone, and three distinct subzones of the columnar layer. They have a unique mix of developmental characteristics, giving ...

Oogenus
Egg fossils are the fossilized remains of eggs laid by ancient animals. As evidence of the physiological processes of an animal, egg fossils are considered a type of trace fossil. Under rare circumstances a fossil egg may preserve the remains of the once- developing embryo inside, in which case it also contains body fossils. A wide variety of different animal groups laid eggs that are now preserved in the fossil record beginning in the Paleozoic. Examples include invertebrates like ammonoids as well as vertebrates like fishes, possible amphibians, and reptiles. The latter group includes the many dinosaur eggs that have been recovered from Mesozoic strata. Since the organism responsible for laying any given egg fossil is frequently unknown, scientists classify eggs using a parallel system of taxonomy separate from but modeled after the Linnaean system. This "parataxonomy" is called ''veterovata''. History The first named oospecies was '' Oolithes bathonicae'', a name given provisi ...

Shixingoolithus
''Shixingoolithus'' is an oogenus of dinosaur egg from the Cretaceous of Nanxiong, China.Z. Zhao, J. Ye, H. Li, Z. Zhao, and Z. Yan. 1991. Extinction of the dinosaurs across the Cretaceous-Tertiary boundary in Nanxiong Basin, Guangdong Province. Vertebrata PalAsiatica 29(1):1-20Carpenter, K. 1999. Eggs, Nests, and Baby Dinosaurs: A Look at Dinosaur Reproduction (Life of the Past). Indiana University Press, Bloomington, Indiana. Description ''Shixingoolithus'' eggs are nearly spherical, and about 12 cm in diameter, with a shell thickness of 2.3-2.6 mm. The shell is made up of tall, prismatic units, and has narrow, irregular pore canals. Its cone layer (mammillae) is approximately a fourth of the shell thickness.Zhao, Z.K. (1994).

Zhejiang
Zhejiang ( or , ; , also romanized as Chekiang) is an eastern, coastal province of the People's Republic of China. Its capital and largest city is Hangzhou, and other notable cities include Ningbo and Wenzhou. Zhejiang is bordered by Jiangsu and Shanghai to the north, Anhui to the northwest, Jiangxi to the west and Fujian to the south. To the east is the East China Sea, beyond which lies the Ryukyu Islands. The population of Zhejiang stands at 64.6 million, the 8th highest among China. It has been called 'the backbone of China' due to being a major driving force in the Chinese economy and being the birthplace of several notable persons, including the Chinese Nationalist leader Chiang Kai-shek and entrepreneur Jack Ma. Zhejiang consists of 90 counties (incl. county-level cities and districts). The area of Zhejiang was controlled by the Kingdom of Yue during the Spring and Autumn period. The Qin Empire later annexed it in 222 BC. Under the late Ming dynasty and the Qing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Cretaceous
The Late Cretaceous (100.5–66 Ma) is the younger of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Australia and Anta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henan
Henan (; or ; ; alternatively Honan) is a landlocked province of China, in the central part of the country. Henan is often referred to as Zhongyuan or Zhongzhou (), which literally means "central plain" or "midland", although the name is also applied to the entirety of China proper. Henan is a birthplace of Han Chinese civilization, with over 3,200 years of recorded history and remained China's cultural, economic and political center until approximately 1,000 years ago. Henan Province is home to many heritage sites, including the ruins of Shang dynasty capital city Yin and the Shaolin Temple. Four of the Eight Great Ancient Capitals of China, Luoyang, Anyang, Kaifeng and Zhengzhou, are in Henan. The practice of tai chi also began here in Chen Jia Gou Village (Chen style), as did the later Yang and Wu styles. Although the name of the province () means "south of the ellowriver.", approximately a quarter of the province lies north of the Yellow River, also known as the Hu ...

Gobi Desert
The Gobi Desert (Chinese: 戈壁 (沙漠), Mongolian: Говь (ᠭᠣᠪᠢ)) () is a large desert or brushland region in East Asia, and is the sixth largest desert in the world. Geography The Gobi measures from southwest to northeast and from north to south. The desert is widest in the west, along the line joining the Lake Bosten and the Lop Nor (87°–89° east). In 2007, it occupied an arc of land in area. In its broadest definition, the Gobi includes the long stretch of desert extending from the foot of the Pamirs (77° east) to the Greater Khingan Mountains, 116–118° east, on the border of Manchuria; and from the foothills of the Altay, Sayan, and Yablonoi mountain ranges on the north to the Kunlun, Altyn-Tagh, and Qilian mountain ranges, which form the northern edges of the Tibetan Plateau, on the south. A relatively large area on the east side of the Greater Khingan range, between the upper waters of the Songhua (Sungari) and the upper waters of the Liao-h ...
