Rewaconodon Indicus
''Rewaconodon'' is an extinct genus of dromatheriid cynodonts which existed in India during the upper Triassic period. It is known from two species: ''R. tikiensis'' and ''R. indicus'', both of which were found in the Tiki Formation. Other, undescribed species In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named.

Dromatheriid
Dromatheriidae is an extinct family of prozostrodontian cynodonts, closely related to mammals. Members of the family are known from the Late Triassic (Carnian to Rhaetian) of India, Europe and North America. Apart from a few jaw fragments, dromatheriids are mainly known from their sectorial (flesh-slicing) postcanine teeth. The teeth were fairly typical among early prozostrodontians, as they were labiolingually compressed (flattened sideways), with a single root and crown hosting a longitudinal row of sharp cusps. Dromatheriids in particular have a very narrow and symmetrical crown (when seen from above) without a prominent cingulum (a ridge or array of cuspules adjacent to the main cusps). Dromatheriid teeth on average have four main cusps, though some have as few as two ('' Dromatherium'') or three ('' Tricuspes''), or as many as six ('' Inditherium'', '' Pseudotriconodon''). Although the teeth have a single root, a vertical furrow on each side of the root appears to be a tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynodont
Cynodontia () is a clade of eutheriodont therapsids that first appeared in the Late Permian (approximately 260 Megaannum, mya), and extensively diversified after the PermianāTriassic extinction event. Mammals are cynodonts, as are their extinct ancestors and close relatives (Mammaliaformes), having evolved from advanced probainognathian cynodonts during the Late Triassic. Non-mammalian cynodonts occupied a variety of ecological niches, both as carnivores and as herbivores. Following the emergence of mammals, most other cynodont lines went extinct, with the last known non-mammaliaform cynodont group, the Tritylodontidae, having its youngest records in the Early Cretaceous. Description Early cynodonts have many of the skeletal characteristics of mammals. The teeth were fully differentiated and the braincase bulged at the back of the head. Outside of some Crown group, crown-group mammals (notably the therians), all cynodonts probably laid eggs. The temporal fenestrae#Fenestra ...

India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...

Triassic
The Triassic ( ; sometimes symbolized š) is a geologic period and system which spans 50.5 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.4 Mya. The Triassic is the first and shortest period of the Mesozoic Era and the seventh period of the Phanerozoic Eon. 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 PermianāTriassic 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiki Formation
The Tiki Formation is a Late Triassic (Carnian to Norian) geologic Formation (geology), formation in Madhya Pradesh, northern India. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. Phytosaur remains attributable to the genus ''Volcanosuchus'' have also been found in the Tiki Formation.Chatterjee, 1978 The genera ''Tikiodon'', ''Tikitherium'' and ''Tikisuchus'' and species ''Rewaconodon, Rewaconodon tikiensis'', ''Hyperodapedon, Hyperodapedon tikiensis'' and ''Parvodus, Parvodus tikiensis'' have been named after the Tiki Formation. Paleobiota Cynodonts Reptiles Teeth similar to ''Galtonia'', ''Protecovasaurus'', and ''Azendohsaurus'' are known from the formation. Claws similar to Shuvosauridae, shuvosaurids and Dinosaur, dinosaurs have also been reported, though their exact identification is questionable.

Annals Of Carnegie Museum
''Annals of Carnegie Museum'' is a peer-reviewed academic journal published by the Carnegie Museum of Natural History. It was established in 1901 by the Board of Trustees of the Carnegie Institute. The journal is distributed both in print and online. The museum's Office of Scientific Publications also publishes the '' Bulletin of Carnegie Museum of Natural History'' and '' Special Publications of Carnegie Museum''. The journal is abstracted and indexed in the Science Citation Index, Scopus, Biosis, and GEOBASE. According to the ''Journal Citation Reports'', the journal has a 2014 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a type of journal ranking. Journals with higher impact factor values are considered more prestigious or important within their field.

Undescribed Species
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a ''nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp.", but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
