Coeluroides Largus
''Coeluroides '' ("hollow form") is an extinct genus of theropod dinosaur that lived during the Late Cretaceous Period in what is now India. It is based solely on the holotype caudal vertebrae GSI K27/562, K27/574 and K27/595, discovered in a layer of the Lameta Formation. The type species, ''C. largus'', was described by Friedrich von Huene and Charles Alfred Matley in 1933. When fully grown, ''Coeluroides'' is estimated at long and perhaps in weight, similar to but larger than '' Jubbulpuria''. ''Coeluroides'' was long considered a ''nomen dubium'' because of sparse remains, but a 2004 overview of Indian theropods from the Lameta Formation found it to be probably valid. An SVP 2012 abstract considers it as a possible senior synonym of '' Ornithomimoides''.Wilson. (2012). Small theropod dinosaurs from the Latest Cretaceous of India.

Late 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 Ant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithomimoides
''Ornithomimoides'' ("bird mimic-like") is a dubious genus of theropod dinosaur, from the Late Cretaceous (Maastrichtian stage, sometime between 70 and 66 mya) Lameta Formation of India. Two species have been identified, the type species ''O. mobilis'' and ''O. barasimlensis'', were named by von Huene in 1932 and were described by Matley in 1933 though they are known only from isolated vertebrae. ''O. barasimlensis'' is known from five dorsal vertebrae, and ''O. mobilis'' from four smaller vertebrae, found at the same location. It is possible that, based on two reviews, published in 1999 and 2004 respectively, ''Ornithomimoides'' may have been an abelisaur, which may have measured between and in length.Novas, Agnolin and Bandyopadhyay.

Fossil Taxa Described In 1933
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 ...

Nomina Dubia
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dinosaurs Of India And Madagascar
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among the ...

Ceratosaurs
Ceratosaurs are members of the clade Ceratosauria, a group of dinosaurs defined as all theropods sharing a more recent common ancestor with ''Ceratosaurus'' than with birds. The oldest known ceratosaur, ''Saltriovenator'', dates to the earliest part of the Jurassic, around 199 million years ago. According to the majority of the latest research, Ceratosauria includes three major clades: Ceratosauridae, Noasauridae, and Abelisauridae, found primarily (though not exclusively) in the Southern Hemisphere. Originally, Ceratosauria included the above dinosaurs plus the Late Triassic to Early Jurassic Coelophysoidea and Dilophosauridae, implying a much earlier divergence of ceratosaurs from other theropods. However, most recent studies have shown that coelophysoids and dilophosaurids do not form a natural group with other ceratosaurs, and are excluded from this group. Ceratosauria derives its names from the type species, ''Ceratosaurus nasicornis'', described by O.C. Marsh in 1884. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timeline Of Ceratosaur Research
This timeline of ceratosaur research is a chronological listing of events in the history of paleontology focused on the ceratosaurs, a group of relatively primitive, often horned, predatory theropod dinosaurs that became the apex predators of the southern hemisphere during the Late Cretaceous. The nature and taxonomic composition of the Ceratosauria has been controversial since the group was first distinguished in the late 19th century. In 1884 Othniel Charles Marsh described the new genus and species ''Ceratosaurus nasicornis'' from the Late Jurassic Morrison Formation of the western United States. He felt that it belonged in a new family that he called the Ceratosauridae. He created the new taxon Ceratosauria to include both the Ceratosauridae and the ostrich-like ornithomimids. The idea of the Ceratosauria was soon contested, however. Later that same decade both Lydekker and Marsh's hated rival Edward Drinker Cope argued that the taxon was invalid. The idea of the Cer ...

Friedrich Von Huene
Friedrich von Huene, born Friedrich Richard von Hoinigen, (March 22, 1875 – April 4, 1969) was a German paleontologist who renamed more dinosaurs in the early 20th century than anyone else in Europe. He also made key contributions about various Permo-Carboniferous limbed vertebrates. Biography Huene was born in Tübingen, Kingdom of Württemberg. His discoveries include the skeletons of more than 35 individuals of ''Plateosaurus'' in the famous Trossingen quarry, the early proto-dinosaur ''Saltopus'' in 1910, ''Proceratosaurus'' in 1926, the giant ''Antarctosaurus'' in 1929, and numerous other dinosaurs and fossilized animals like pterosaurs. He also was the first to naming several higher taxa, including Prosauropoda and Sauropodomorpha. In 1941 he found a stone that had petrified wood in it, sadly, He thought that it was a dinosaur. However a couple Polish paleontologists. The “dinosaur” was called the Succinodon He visited the Geopark of Paleorrota in 1928, and the ...

Jubbulpuria
''Jubbulpuria'' ("Jubbulpore one") is the name given to a dubious genus of small dinosaur from the Late Cretaceous of India. The genus was in 1932 named by Friedrich von Huene. The generic name refers to Jabalpur in India, in the vicinity of which the fossils were found. The type species, ''Jubbulpuria tenuis'', was described by Huene and Charles Alfred Matley in 1933.F. v. Huene and C. A. Matley, 1933, "The Cretaceous Saurischia and Ornithischia of the Central Provinces of India", ''Palaeontologica Indica (New Series), Memoirs of the Geological Survey of India'' 21(1): 1-74 The specific name means "slender" in Latin. Its fossil specimens were found by Matley in the Lameta Formation, dating from the Maastrichtian. They consist of two syntypes, GSI K27/614 and GSI K20/612, each being a partial distal caudal vertebra. A third distal tail vertebra, GSI K27/599, has been referred to the species. ''Jubbulpuria'' was a small predator, estimated to have been high, long, and weighing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In 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 species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
