Qianlong Shouhu
''Qianlong shouhu'' (meaning "Guizhou Province dragon") is an extinct species of basal sauropodomorph dinosaur from the Early Jurassic Ziliujing Formation of China. ''Qianlong shouhu'' is the Monotypic taxon, only species in the genus ''Qianlong'', known from partial skeletons of three mature individuals associated with several eggs, some of which contain embryos. These may represent the oldest leathery eggs currently known. Discovery and naming The ''Qianlong'' fossil material was discovered in sediments of the Ziliujing Formation (Zhenzhuchong Member), dated to the Sinemurian age of the Early Jurassic period near Zhuanpo in Pingba District of Anshun City, Guizhou Province, China. The known material includes the holotype (Guizhou Provincial Museum, GZPM VN001), two referred skeletons (GZPM VN002, 003), and five clutches of eggs, some of which contain hatchlings (GZPM VN004–008). The incomplete, partially-joint, articulated holotype specimen includes a partial skull and mandib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Jurassic
The Early Jurassic Epoch (geology), Epoch (in chronostratigraphy corresponding to the Lower Jurassic series (stratigraphy), Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic–Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.7 ±0.8 Ma. Certain rocks of marine origin of this age in Europe are called "Lias Group, Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an England, English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornwall, Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias and Carbonif ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Chuxiongosaurus
''Chuxiongosaurus'' (meaning "Chuxiong lizard") is a genus of basal sauropodomorph dinosaur which lived during the Early Jurassic Period. Fossils of this genus have been found in the Lower Lufeng Formation, Yunnan Province, southern China. Identified from the holotype CMY LT9401 a nearly complete skull (including a lower jaw) with some similarities to ''Thecodontosaurus'', it was described as the "first basal sauropod dinosaur from the Early Jurassic of China," more basal than '' Anchisaurus''. It was named by Lü Junchang, Yoshitsugu Kobayashi, Li Tianguang and Zhong Shimin in 2010, and the type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ... is ''Chuxiongosaurus lufengensis''. It is a possible junior synonym of '' Jingshanosaurus''. References Massopoda Dinosa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xingxiulong
''Xingxiulong'' (meaning "Xingxiu Bridge dragon") is a genus of bipedal massopodan sauropodomorph from the Early Jurassic of China. It contains two species; the type species is ''X. chengi'', described by Wang et al. in 2017 from three specimens, two adults and an immature individual, that collectively constitute a mostly complete skeleton. Adults of this species measured long and tall. A second species, ''X. yueorum'', was described by Chen et al. in 2025 based on a partial articulated postcranial skeleton of an adult individual larger than ''X. chengi''. Phylogenetic analysis suggests that ''Xingxiulong'' is most closely related to its contemporary ''Jingshanosaurus'', although an alternative position outside of both the Sauropodiformes and Massospondylidae is also plausible. Despite their close relationship, ''Xingxiulong'' prominently differs from ''Jingshanosaurus''—and from most basal sauropodomorphs—in having a number of sauropod-like traits. These include a sacrum c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
