Talenkauen
''Talenkauen'' is a genus of Basal (phylogenetics), basal iguanodont dinosaur from the Campanian or Maastrichtian age of the Late Cretaceous Cerro Fortaleza Formation, formerly known as the Pari Aike Formation of Patagonian Lake Viedma, in the Magallanes Basin, Austral Basin of Santa Cruz Province (Argentina), Santa Cruz, Argentina. It is holotype, based on Museo Padre Molina, MPM-10001A, a partial articulated skeleton missing the rear part of the skull, the tail, and the hands. The type species, type and only species is ''Talenkauen santacrucensis''. Discovery and naming One among a string of discoveries of ornithopods in South America, following taxa such as ''Gasparinisaura'' and ''Anabisetia'', the specimen that would become ''Talenkauen'' was collected in February 2000 and would later be described and named in a short 2004 paper by Fernando E. Novas and colleagues. It was discovered on Los Hornos Hill on the coast of Viedma Lake, in the Santa Cruz Province (Argentina), Sant ...

Cerro Fortaleza Formation
The Cerro Fortaleza Formation, in older literature described as Pari Aike Formation, is a Late Cretaceous geologic formation of Campanian to Maastrichtian age (although it has formerly been reported to be Cenomanian to Santonian) of the Austral Basin in southern Patagonia, Argentina. Description The sandstones of the formation were deposited in a fluvial environment. The formation has an estimated thickness of and overlies the Anita Formation, while it is overlain by the La Irene Formation. These formations are considered Campanian and Maastrichtian in age, respectively, making the Cerro Fortaleza Formation aged between them. Paleobiota The giant titanosaurs '' Puertasaurus'' and '' Dreadnoughtus'', the megaraptoran '' Orkoraptor'', the berthasaurid '' Austrocheirus isasii'', and the ornithopod ''Talenkauen'' have been recovered from the formation alongside turtles and crocodiles.

Gasparinisaura
''Gasparinisaura'' (meaning "Gasparini's lizard") is a genus of herbivorous ornithopod dinosaur from the Late Cretaceous. The first fossils of ''Gasparinisaura'' were found in 1992 near Cinco Saltos in Río Negro Province, Argentina. The type species, ''Gasparinisaura cincosaltensis'', was named and described in 1996 by Rodolfo Coria and Leonardo Salgado. The generic name honors Argentine palaeontologist Zulma Brandoni de Gasparini. The specific name (zoology), specific name refers to Cinco Saltos.Coria, R. A., and L. Salgado. (1996). "A basal iguanodontian (Ornithischia: Ornithopoda) from the Late Cretaceous of South America". ''Journal of Vertebrate Paleontology'' 16: 445–457 Discovery The holotype, MUCPv-208, was uncovered in 1992 in a layer of the Anacleto Formation, dating from the early Campanian, about 83 million years old. It consists of a partial skeleton with skull, lacking much of the vertebral column. The paratype is MUCPv-212, a tail with lower hindlimb elements. ...

Anabisetia
''Anabisetia'' ( ) is a genus of ornithopod dinosaur from the Late Cretaceous Period of Patagonia, South America. It was a small bipedal herbivore, around long. Discovery Argentine paleontologists Rodolfo Coria and Jorge Orlando Calvo named ''Anabisetia'' in 2002. The generic name honors the late Ana Maria Biset, an influential archeologist from Neuquén Province in Argentina, where the remains of this animal were found. The one named species is called ''A. saldiviai'', after Roberto Saldivia Blanco, a local farmer who had discovered the fossils in 1985 and brought them to the attention of science in 1993.Coria, R.A. & Calvo, J.O. 2002.

Iguanodont
Ornithopoda () is a clade of ornithischian dinosaurs, called ornithopods (). They represent one of the most successful groups of herbivore, herbivorous dinosaurs during the Cretaceous. The most primitive members of the group were bipedal and relatively small-sized, while advanced members of the subgroup Iguanodontia became quadrupedal and developed large body size. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex of diversity and ecological dominance in the Hadrosauridae, hadrosaurids (colloquially known as 'duck-bills'), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non-aves, avian dinosaurs. Members are known worldwide. History of research In 1870, Thomas Henry Huxley listed Iguanodontidae (coined by Edward Drinker Cope a year earlier) ...

Viedma Lake
Viedma Lake (, ) is a Patagonian lake in the province of Santa Cruz, Argentina, situated near its border with Chile. Measuring approximately 50 miles (80 kilometers) in length, it is a major elongated trough lake formed from melting glacial ice. Viedma Lake is the second largest perennial lake located entirely within Argentina."Principal Lagos de la Republica Argentina", http://www.ign.gob.ar/NuestrasActividades/Geografia/DatosArgentina/Lagos, accessed 20 Jul 2018. Note that this list does not include an area figure for the large but seasonal Mar Chiquita. The name of the lake comes from the Spanish explorer Antonio de Viedma, who in 1783 reached its shores, being the first European to do so. The town of El Chaltén and the Andes peaks Cerro Torre and Fitz-Roy lie in the proximity of Lake Viedma. Lake Viedma is fed primarily by the Viedma Glacier at its western end. The Viedma Glacier measures 3 miles (5 kilometers) wide at its terminus at Lake Viedma. The brown landscape i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mata Amarilla Formation
The Mata Amarilla Formation is a List of fossiliferous stratigraphic units of Argentina, fossiliferous formation of the Magallanes Basin, Austral Basin in southern Patagonia, Argentina. The formation consists of sediments deposited during the Cenomanian, Middle Cenomanian, dated to 96.94 to 95.52 Ma. The middle section of the formation was previously considered to be the Pari Aike Formation. The Mata Amarilla Formation has provided many fossil vertebrates, among which dinosaurs, fish and turtles, as well as fossil insects, flora and molluscs. Age The middle section of the Mata Amarilla Formation has widely been regarded as Maastrichtian in age, but recent dating of a lava tuff layer shows that it dates back to 96.2 ± 0.7 Ma, during the Cenomanian.Varela et al., 2012 Description The Austral (or Magallanes) Basin, is located on the southwestern end of the South American Plate and it is bordered to the south by the Scotia Plate covering an area of approximately .

Aonikenk
Tehuelche (''Aoniken, Inaquen, Gunua-Kena, Gununa-Kena'') is one of the Chonan languages of Patagonia. Its speakers, the Tehuelche people, were nomadic hunters who occupied territory in present-day Chile, north of Tierra del Fuego and south of the Mapuche people. It is also known as ''Aonekkenk'' or ''Aonekko ʼaʼien'' (). The decline of the language started with the Mapuche invasion in the north, that was then followed by the occupation of Patagonia by the Argentine and Chilean states and state-facilitated genocide. Tehuelche was considerably influenced by other languages and cultures, in particular Mapudungun (the language of the Mapuche). This allowed the transference of morpho-syntactic elements into Tehuelche. During the 19th and 20th centuries, Spanish became the dominant language as Argentina and Chile gained independence, and Spanish-speaking settlers took possession of Patagonia. Because of these factors the language began dying out. In 1983/84 there were 29 speakers, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campanian
The Campanian is the fifth of six ages of the Late Cretaceous epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campanian spans the time from 83.6 (± 0.2) to 72.1 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian. The Campanian was an age when a worldwide sea level rise covered many coastal areas. The morphology of some of these areas has been preserved: it is an unconformity beneath a cover of marine sedimentary rocks. Etymology The Campanian was introduced in scientific literature by Henri Coquand in 1857. It is named after the French village of Champagne in the department of Charente-Maritime. The original type locality was a series of outcrops near the village of Aubeterre-sur-Dronne in the same region. Definition The base of the Campanian Stage is defined as a place in the stratigraphic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryosaurus
''Dryosaurus'' ( , meaning 'tree lizard', Greek ' () meaning 'tree, oak' and () meaning 'lizard', (the name reflects the forested habitat, not a vague oak-leaf shape of its cheek teeth as is sometimes assumed) is a genus of an ornithopod dinosaur that lived in the Late Jurassic period. It was an iguanodont (formerly classified as a hypsilophodont). Fossils have been found in the western United States and were first discovered in the late 19th century. '' Valdosaurus canaliculatus'' and '' Dysalotosaurus lettowvorbecki'' were both formerly considered to represent species of ''Dryosaurus''. Description Based on known specimens, ''Dryosaurus'' has been estimated to have reached up to long and to have weighed up to . However, as no known adult specimens of the genus have been found, the adult size remains unknown. In 2018, the largest specimen (CM 1949) was concluded to be from another species; revising the identity of this specimen put the previous research on size and growth i ...
