<i>Eoraptor</i> Extinct genus of dinosaurs

Eoraptor is a genus of small, lightly built, basal sauropodomorph. One of the earliest-known dinosaurs and one of the earliest members of the sauropod family, it lived approximately 231 to 228 million years ago, during the Late Triassic in Western Gondwana, in the region that is now northwestern Argentina. The type and only species, Eoraptor lunensis, was first described in 1993, and is known from an almost complete and well-preserved skeleton and several fragmentary ones. Eoraptor had multiple tooth shapes, which suggests that it was omnivorous.Eoraptor was 1.5 feet tall and 3 feet long.

<span class="mw-page-title-main">Tetanurae</span> Clade containing most theropod dinosaurs

Tetanurae is a clade that includes most theropod dinosaurs, including megalosauroids, allosauroids, tyrannosauroids, ornithomimosaurs, compsognathids and maniraptorans. Tetanurans are defined as all theropods more closely related to modern birds than to Ceratosaurus and contain the majority of predatory dinosaur diversity. Tetanurae likely diverged from its sister group, Ceratosauria, during the late Triassic. Tetanurae first appeared in the fossil record by the Early Jurassic about 190 mya and by the Middle Jurassic had become globally distributed.

<i>Neuquenraptor</i> Extinct genus of dinosaurs

Neuquenraptor is a genus of dromaeosaurid theropod dinosaurs that lived in South America during the Late Cretaceous in what is now the Portezuelo Formation of Argentina. It is one of the first dromaeosaurids found in the Southern Hemisphere.

<i>Megaraptor</i> Extinct genus of dinosaurs

Megaraptor is a genus of large theropod dinosaur that lived in the ages of the Late Cretaceous. Its fossils have been discovered in the Patagonian Portezuelo Formation of Argentina, South America. Initially thought to have been a giant dromaeosaur-like coelurosaur, it was classified as a neovenatorid allosauroid in previous phylogenies, but more recent phylogeny and discoveries of related megaraptoran genera has placed it as either a basal tyrannosauroid or a basal coelurosaur with some studies still considering it a neovenatorid.

Unenlagia is a genus of dromaeosaurid theropod dinosaur that lived in South America during the Late Cretaceous period. The genus Unenlagia has been assigned two species: U. comahuensis, the type species described by Novas and Puerta in 1997, and U. paynemili, described by Calvo et al. in 2004.

The Huincul Formation is a geologic formation of Late Cretaceous age of the Neuquén Basin that outcrops in the Mendoza, Río Negro and Neuquén Provinces of northern Patagonia, Argentina. It is the second formation in the Río Limay Subgroup, the oldest subgroup within the Neuquén Group. Formerly that subgroup was treated as a formation, and the Huincul Formation was known as the Huincul Member.

<i>Orkoraptor</i> Extinct genus of dinosaurs

Orkoraptor is a genus of medium-sized megaraptoran theropod dinosaur from the late Cretaceous Period of Argentina. It is known from incomplete fossil remains including parts of the skull, teeth, tail vertebrae, and a partial tibia. The specialized teeth resemble those of some maniraptoriform theropods, namely the deinonychosaurs and compsognathids. This and other anatomical features led the authors who described it to suggest that it was a maniraptoran coelurosaur. However, subsequent studies found it to be a megaraptoran. Found in the Cerro Fortaleza Formation of Southern Patagonia, it is one of the southernmost carnivorous dinosaurs known from South America.

<span class="mw-page-title-main">Megaraptora</span> Extinct clade of dinosaurs

Megaraptora is a clade of carnivorous tetanuran theropod dinosaurs with controversial relations to other theropods. Its derived members, the Megaraptoridae are noted for their large hand claws and robust forelimbs, which are usually reduced in size in other large theropods.

<span class="mw-page-title-main">Chorrillo Formation</span>

The Chorrillo Formation, also named as Chorillo Formation, is a Maastrichtian geologic formation in southern Patagonia, Argentina. The formation is more than 50 metres (160 ft) thick and underlies the Calafate Formation and rests on top of the La Irene Formation.

<i>Austrocheirus</i> Genus of reptiles (fossil)

Austrocheirus is an extinct genus of theropod dinosaur, possibly a neoceratosaurian, which existed during the Late Cretaceous period. It was named and described by Martin Ezcurra, Federico Agnolin and Fernando Novas in 2010. It contains the type species Austrocheirus isasii. The generic name means "southern hand". The specific epithet honours discoverer and preparator Marcelo Pablo Isasi.

<i>Chilesaurus</i> Extinct genus of dinosaur

Chilesaurus is an extinct genus of herbivorous dinosaur. The type and only known species so far is Chilesaurus diegosuarezi. Chilesaurus lived about 145 million years ago (Mya) in the Late Jurassic period of Chile. Showing a combination of traits from theropods, ornithischians, and sauropodomorphs, this genus has far-reaching implications for the evolution of dinosaurs, such as whether the traditional saurischian-ornithischian split is superior or inferior to the proposed group Ornithoscelida.

<span class="mw-page-title-main">Timeline of ceratosaur research</span>

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.

<span class="mw-page-title-main">Toqui Formation</span> Geologic formation in the Aysén Region, Chile

The Toqui Formation is a geological formation in the Aysén Region of southern Chile. It has been dated to the Tithonian stage of the Late Jurassic by uranium–lead dating of zircons, providing an age of 147 ± 0.1 Ma. It consists of an sequence of clastic sedimentary sandstones and conglomerates, interbedded with volcanic tuffs and ignimbrite. The dinosaurs Chilesaurus and indeterminate diplodocids and the mesoeucrocodylian Burkesuchus are known from the formation. The formation was deposited in a fluvio-deltaic environment.

<i>Overoraptor</i> Extinct genus of dinosaurs

Overoraptor is a genus of paravian theropod dinosaurs, which was closely related to Rahonavis, from the Late Cretaceous (Cenomanian) Huincul Formation of Gondwana, present-day Argentina. It includes one species, Overoraptor chimentoi.

<i>Burkesuchus</i> Extinct genus of reptiles

Burkesuchus is an extinct genus of basal neosuchians from the Upper Jurassic (Tithonian)-aged Toqui Formation of southern Chile. The genus is currently represented by a single species B. mallingrandensis, named and described in 2021 on the basis of the holotype and additional referred specimens. Burkesuchus mallingrandensis was noticeably small being around an estimated 70 cm in length. The cranium is dorsoventrally depressed and transversely wide posteriorly and distinguished by a posteroventrally flexed wing-like squamosal. Burkesuchus was a small carnivore likely on invertebrates animals such as insects, crustaceans and may had feed on small aquatic vertebrates like fish. B. mallingrandensis did not have the ability to feed on large prey items or tear large chunks of meat like modern day crocodiles do. The holotype SQO.PV 17700, consist of a cervical neural arch, partial neurocranium, four dorsal vertebrae, right scapula, a right coracoid, right humerus, a ulna, left ischium, distal end of the right femur, one cervical and two dorsal osteoderms. The paratype SQO.PV 17701 fossil remains consist of a nearly complete right femur, two doral vertebrae and one dorsal osteoderm. The fossils was discovered in 2014 but was described as a new genus and species on July 23, 2021.

Kookne is a prehistoric bird genus from the Late Cretaceous. Known from a coracoid, the remains of the only known species Kookne yeutensis were found in rocks from the Late Cretaceous (Maastrichtian) Chorrillo Formation of Santa Cruz, Argentina.
