Huinculsaurus
''Huinculsaurus'' (meaning "Huincul Formation lizard") is a genus of noasaurid dinosaur from the Huincul Formation in Neuquén Province, Argentina. The type and only species is ''Huinculsaurus montesi''. It was probably around when fully grown, although this is only speculation since no fully mature specimens are currently known. Discovery and naming ''Huinculsaurus'' is only known from three thoracic and two sacral vertebrae from an immature individual, discovered . It was discovered ten meters away from where the ''Ilokelesia'' holotype was discoveredCoria, R.A.; Salgado, L. & Calvo, J.O.

Elaphrosaurinae
Noasauridae is an extinct family of theropod dinosaurs belonging to the group Ceratosauria. They were closely related to the short-armed Abelisauridae, abelisaurids, although most noasaurids had much more traditional body types generally similar to other theropods. Their heads, on the other hand, had unusual adaptations depending on the subfamily. 'Traditional' noasaurids, sometimes grouped in the subfamily Noasaurinae, had sharp teeth which splayed outwards from a downturned lower jaw. The most complete and well-known example of these kinds of noasaurids was ''Masiakasaurus knopfleri'' from Madagascar. Another group, Elaphrosaurinae, has also been placed within Noasauridae by some studies. Elaphrosaurines developed toothless jaws and herbivorous diets, at least as adults. The most complete and well known elaphrosaurine was ''Limusaurus, Limusaurus inextricabilis''. At least some noasaurids had pneumatised cervical vertebrae.Arthur Souza Brum, Elaine Batista Machado, Diogene ...

Limusaurus
''Limusaurus'' is a genus of theropod dinosaur that lived in what is now China during the Late Jurassic, around 161 to 157 million years ago. The type and only species ''Limusaurus inextricabilis'' was described in 2009 from specimens found in the Upper Shishugou Formation in the Junggar Basin of China. The genus name consists of the Latin words for "mud" and "lizard", and the species name means "impossible to extricate", both referring to these specimens possibly dying after being mired. ''Limusaurus'' was a small, slender animal, about in length and in weight, which had a long neck and legs but very small forelimbs (with reduced first and fourth fingers). It underwent a drastic morphological transformation as it aged: while juveniles were toothed, these teeth were completely lost and replaced by a beak with age. Several of these features were convergently similar to the later ornithomimid theropods as well as the earlier non-dinosaurian shuvosaurids. ''Limusaurus ...

Ilokelesia
''Ilokelesia'' is an extinct genus of abelisaurid theropod,Coria, R.A.; Salgado, L. & Calvo, J.O.

''Ameghiniana'', 28: 405-406. preserved in the layers of the earliest Late Cretaceous of the Huincul Formation, Neuquén Group, located near Plaza Huincul, Neuquén Province, Argentina. The specimen, consisting of very fragmentary elements of the skull and the axial and appendicular skeleton, was described by Rodolfo Coria and Leonardo Salgado in late 1998. Discovery and naming ''Ilokelesia'' is only known from very fragmentary elements of the skull and the axial and appendicular skeleton, discovered in 1991. It was discovered ten meters away from where the holotype of ''Huinculsaurus'' was discovered. The genus was named and described in 1998. Etymology The generic name's etymology is derived from the Mapuche language, ''ilo'' meani ...

Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosau ...

Elaphrosaurus
''Elaphrosaurus'' ( ) is a genus of ceratosaurian theropod dinosaur that lived approximately 154 to 150 million years ago during the Late Jurassic Period in what is now Tanzania in Africa. ''Elaphrosaurus'' was a medium-sized but lightly built member of the group that could grow up to long. Morphologically, this dinosaur is significant in two ways. Firstly, it has a relatively long body but is very shallow-chested for a theropod of its size. Secondly, it has very short hindlimbs in comparison with its body. Phylogenetic analyses indicate that this genus is likely a ceratosaur. Earlier suggestions that it is a late surviving coelophysoid have been examined but generally dismissed. ''Elaphrosaurus'' is currently believed to be a very close relative of ''Limusaurus'', an unusual beaked ceratosaurian which may have been either herbivorous or omnivorous. Discovery The type specimen of ''Elaphrosaurus bambergi'' HMN Gr.S. 38–44 was recovered in the Middle Dinosaur Member of the ...

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 ...
