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 spo ...

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 Spheroolithidae, Spheroolithids, in the case of Coralloidoolithus, ''"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 uniq ...

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 gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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).

Upper Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent 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, Austral ...

Henan
Henan; alternatively Honan is a province in Central China. Henan is home to many heritage sites, including Yinxu, the ruins of the final capital of the Shang dynasty () and the Shaolin Temple. Four of the historical capitals of China, Luoyang, Anyang, Kaifeng and Zhengzhou, are in Henan. While the province's name means 'south of the river', approximately a quarter of the province lies north of the Yellow River. With an area of , Henan covers a large part of the fertile and densely populated North China Plain. Its neighboring provinces are Shaanxi, Shanxi, Hebei, Shandong, Anhui, and Hubei. Henan is China's third-most populous province and the most populous among inland provinces, with a population of over 99 million as of 2020. It is also the world's seventh-most populous administrative division; if it were a country by itself, Henan would be the 17th-most populous in the world, behind Egypt and Vietnam. People from Henan often suffer from regional discrimination ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gobi Desert
The Gobi Desert (, , ; ) is a large, cold desert and grassland region in North China and southern Mongolia. It is the sixth-largest desert in the world. The name of the desert comes from the Mongolian word ''gobi'', used to refer to all of the waterless regions in the Mongolian Plateau; in Chinese, ''gobi'' is used to refer to rocky, semi-deserts such as the Gobi itself rather than sandy deserts. 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). Its area is approximately . 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 Pla ...
