Kannemeyeriiformes
Kannemeyeriiformes is a group of large-bodied Triassic dicynodonts. As a clade, Kannemeyeriiformes has been defined to include the species ''Kannemeyeria simocephalus'' and all dicynodonts more closely related to it than to the species '' Lystrosaurus murrayi''. Evolutionary history Despite being the most species-rich group of dicynodonts in the Triassic Period, kannemeyeriiforms exhibit much less diversity in terms of their anatomy and ecological roles than the dicynodonts from the Permian Period. Lystrosauridae is thought to be the most closely related group (sister taxon) to Kannemeyeriiformes, and since the earliest lystrosaurids are known from the Late Permian, the divergence of these two groups must have occurred at least as far back as this time, implying that a long ghost lineage must exist. Although no kannemeyeriiforms have been found in the Late Permian yet, the recent discovery of ''Sungeodon'' helps fill a gap in the early fossil record of the group by showing that k ...

Dicynodont
Dicynodontia is an extinct clade of anomodonts, an extinct type of non-mammalian therapsid. Dicynodonts were herbivorous animals with a pair of tusks, hence their name, which means 'two dog tooth'. Members of the group possessed a horny, typically toothless beak, unique amongst all synapsids. Dicynodonts first appeared in Southern Pangaea during the mid-Permian, ca. 270–260 million years ago, and became globally distributed and the dominant herbivorous animals in the Late Permian, ca. 260–252 Mya. They were devastated by the end-Permian Extinction that wiped out most other therapsids ca. 252 Mya. They rebounded during the Triassic but died out towards the end of that period. They were the most successful and diverse of the non-mammalian therapsids, with over 70 genera known, varying from rat-sized burrowers to elephant-sized browsers. Characteristics The dicynodont skull is highly specialised, light but strong, with the synapsid temporal openings at the rear of the skull ...

Anisian
In the geologic timescale, the Anisian is the lower stage or earliest age of the Middle Triassic series or epoch and lasted from million years ago until million years ago. The Anisian Age succeeds the Olenekian Age (part of the Lower Triassic Epoch) and precedes the Ladinian Age. Stratigraphic definitions The stage and its name were established by Austrian geologists Wilhelm Heinrich Waagen and Carl Diener in 1895. The name comes from ''Anisus'', the Latin name of the river Enns. The original type locality is at Großreifling in the Austrian state of Styria. The base of the Anisian Stage (also the base of the Middle Triassic series) is sometimes laid at the first appearance of conodont species '' Chiosella timorensis'' in the stratigraphic record. Other stratigraphers prefer to use the base of magnetic chronozone MT1n. There is no accepted global reference profile for the base, but one ( GSSP or golden spike) was proposed at a flank of the mountain Deşli Caira in the Roman ...

Geological Museum Of China
The Geological Museum of China (), built in 1916, is a geological museum, boasting 200 thousand specimens. This museum is located in the Xisi area of Beijing and opened on October 1, 1959. It is the earliest geological scientific museum of China. At present, the Geological Museum of China has more than 100,000 geological specimens. Many of them are precious items reputed as "National Treasures", such as "the Giant Shandong Dinosaur"('' Shantungosaurus'') fossil, the most complete dinosaur fossils extant in the world excavated from Liaoning; the fossils of primitive birds that were found in the west of Liaoning Province, which has the essential values to the research on birds of the area; the teeth fossils of Yunnan Yuanmou Man, which shifts the appearance of human beings in China to a much more earlier time; the stoneware, stone pearls, bone needles and bone decoration unearthed from the site of the Upper Cave man at Zhoukoudian in Beijing; a cinnabar crystal of 237 grams that ...

Kelamayi Formation
Karamay is a prefecture-level city in the north of the Xinjiang Uyghur Autonomous Region, People's Republic of China. The name of the city comes from the Uyghur language and means "black oil", referring to the oil fields near the city. Karamay was the site of one of the worst disasters in modern Chinese history, the 1994 Karamay fire, when 324 people, including 288 school children, lost their lives in a cinema fire on 8 December 1994. Karamay is an exclave of Tacheng Prefecture. History Subdivisions Karamay City has jurisdiction over four districts ( zh, s=区, p=qū, labels=no). They are not contiguous as Dushanzi District is located south of the Lanxin Railway and forms an exclave, separated from the rest of Karamay City by Kuytun City. Together with Kuytun City, Karamay City forms an enclave surrounded on all sides by Tacheng Prefecture. Geography Karamay is located in the northwest of the Dzungarian basin, with an average elevation of . Its administrative area ranges i ...

Triassic Synapsids Of Asia
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Fossils Of China
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...
