Uberabatitan
''Uberabatitan'' (meaning "Uberaba titan", in reference to where it was found) is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous of Brazil. It is known from bones including neck, back, and tail vertebrae, pelvic bones, and limb bones. These fossils were found in the uppermost portion of the Maastrichtian-age Serra da Galga Formation of the Bauru Group, in Uberaba, Minas Gerais. The type species, described by Salgado and Carvalho in 2008, is ''U. ribeiroi''. To date, it is the most recent titanosaur from Bauru Group rocks; other titanosaurs from the Bauru Group, including ''Baurutitan'' and '' Trigonosaurus'', come from lower (thus older) levels. Like other sauropods, ''Uberabatitan'' would have been a large quadrupedal herbivore A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet.

Austroposeidon
''Austroposeidon'' is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Presidente Prudente Formation of Brazil. It contains one species, ''Austroposeidon magnificus'' (meaning "Magnificent Southern Poseidon"). Discovery and naming ''Austroposeidon'' is known from a single specimen, MCT 1628-R, which consists of portions of the cervical (neck), dorsal (back), and sacral (hip) vertebrae (including a cervical rib and one complete dorsal vertebra). The specimen was discovered in the Campanian-Maastrichtian Presidente Prudente Formation of the Bauru Group by palaeontologist Llewellyn Ivor Price in 1953, but the remains were not described until 2016. The animal was likely preserved by a crevasse splay on a floodplain, judging by the fine sandstone that the specimen was found in. Unfortunately, the site where the specimen was recovered has now been lost to urban development. The genus name combines ''austro'' ("southern", as in South America, from Latin ''Auster'', ...

Titanosaur
Titanosaurs (or titanosaurians; members of the group Titanosauria) were a diverse group of sauropod dinosaurs, including genera from all seven continents. The titanosaurs were the last surviving group of long-necked sauropods, with taxa still thriving at the time of the extinction event at the end of the Cretaceous. This group includes some of the largest land animals known to have ever existed, such as ''Patagotitan''—estimated at long with a weight of —and the comparably-sized ''Argentinosaurus'' and ''Puertasaurus'' from the same region. The group's name alludes to the mythological Titans of ancient Greek mythology, via the type genus (now considered a '' nomen dubium)'' ''Titanosaurus''. Together with the brachiosaurids and relatives, titanosaurs make up the larger sauropod clade Titanosauriformes. Titanosaurs have long been a poorly-known group, and the relationships between titanosaur species are still not well-understood. Description Titanosauria have the largest ...

Lognkosauria
Lognkosauria is a clade of giant long-necked sauropod dinosaurs within the clade Titanosauria. It includes some of the largest and heaviest dinosaurs known. Description Lognkosaurians can be distinguished from other titanosaurs by the wide and unusually thick cervical rib loops on their neck vertebrae, their extremely robust neck neural spines, the relatively narrow neural canal, and their huge vaulted neural arches. They also had very wide dorsal vertebrae with wing-like side processes, and extremely wide rib cages. Their dorsal side processes are also fairly in-line with the level of the neural canal, instead of being attached further up the neural arch as in lithostrotians. Skull material from ''Malawisaurus'', the sister taxon to Lognkosauria, indicates that lognkosaurians at least began with the big-nosed, rounded head shape of earlier titanosaurs and more basal macronarians. Classification Lognkosauria was defined as the clade encompassing the most recent common ancestor o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Herbivore
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material. A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This flora is made up of cellulose-digesting protozoans or bacteria. Etymology Herbivore is the anglicized form of a modern Latin coinage, ''herbivora'', cited in Charles Lyell's 1830 ''Principles of Geology''.J.A. Simpson and E.S.C. Weiner, eds. (2000) ''The Oxford English Dictionary'', vol. 8, p. 155. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. ''Herbivora'' is derived from Latin ''herba' ...

Isisaurus
''Isisaurus'' (named after the Indian Statistical Institute) is a genus of titanosaurian dinosaur from the Late Cretaceous Lameta Formation of India. The genus contains a single species, ''Isisaurus colberti''. Discovery and Naming The type specimen of ''Isisaurus colberti'', ISI R 335/1-65, was originally described and named as ''Titanosaurus colberti'' by Sohan Lal Jain and Saswati Bandyopadhyay in 1997. The specific name honours Edwin Harris Colbert. In 2003, the fossils were designated as belonging to its own genus by Wilson and Upchurch. The generic name, "''Isisaurus''," combines a reference to the Indian Statistical Institute (ISI) with the Greek "saurus," meaning "lizard." It had a short, vertically directed neck and long forelimbs, making it considerably different from other sauropods. The humerus is 148 centimetres long. ''Isisaurus'' is known from better remains than many other titanosaurs that were known at the time of its description. Much of its postcranial ske ...

Quetecsaurus
''Quetecsaurus'' (meaning "fire lizard", from the Milcayac word "quetec") is a genus of titanosaurian sauropod dinosaur known from the Late Cretaceous of the southern Mendoza Province, western Argentina. It contains a single species, ''Quetecsaurus rusconii''. Discovery ''Quetecsaurus'' was first described and named by Bernardo González Riga and Leonardo Ortiz David in 2014. The type species is ''Quetecsaurus rusconii''. It is known solely from the holotype, a partial skeleton found in close association that includes a postorbital, teeth, the atlas, a rear cervical vertebra, an incomplete dorsal vertebra, a rear caudal centrum, dorsal ribs, a coracoid, five metacarpals and fragments of a humerus, radius and ulna. The holotype was collected from red mudstones of the Cerro Lisandro Formation, Neuquén Basin, dating to the middle or late Turonian stage of the Late Cretaceous. The specimen represents the first sauropod with well preserved materials from this formation. Descri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Futalognkosaurus
''Futalognkosaurus'' ( ; meaning "giant chief lizard") is a genus of titanosaurian dinosaur. The herbivorous ''Futalognkosaurus'' lived approximately 87 million years ago in the Portezuelo Formation, in what is now Argentina, of the Coniacian stage of the late Cretaceous Period. The fish and fossilized leaf debris on the site, together with other dinosaur remains, suggest a warm tropical climate in Patagonia during this period. Discovery Fossils of ''Futalognkosaurus'' were found in the Neuquén province of Argentina in 2000, and were scientifically described in 2007, alongside sauropods, ''Megaraptor'', ''Unenlagia'', iguanodonts, peirosaurids, and pterosaurs. The holotype was found near the margins of a river. The holotype was hypothesised to have been washed into the river after its death. Due to its giant size the carcass likely acted as a barrier, altering thr colurse of the river around it, lasting long enough for fish and bivalves to live in ir, and eventually creating an ...

Mendozasaurus
''Mendozasaurus'' is a genus of titanosaurian sauropod dinosaur. It was a member of Titanosauria, which were massive sauropods that were common on the southern landmasses during the Cretaceous. It is represented by several partial skeletons from a single locality within the Coniacian (lower Upper Cretaceous) Sierra Barrosa Formation in the south of Mendoza Province, northern Neuquén Basin, Argentina. The type species, ''Mendozasaurus neguyelap'', was described by Argentine paleontologist Bernardo Javier González Riga in 2003. ''Mendozasaurus'' is the first dinosaur named from Mendoza Province, Argentina, for which it was named. Description This species belonged to the discovered clade Lognkosauria, a transitional group of titanosaurs which included the gigantic '' Futalognkosaurus'' and ''Puertasaurus''. Like both of these animals, ''Mendozasaurus'' had a long neck with very wide cervical neural spines. Holtz estimated its length at . In 2010 Gregory S. Paul estimated ''Men ...

Puertasaurus
''Puertasaurus'' is a genus of sauropod dinosaur that lived in South America during the Late Cretaceous Period. It is known from a single specimen recovered from sedimentary rocks of the Cerro Fortaleza Formation in southwestern Patagonia, Argentina, which probably is Campanian or Maastrichtian in age. The only species is ''Puertasaurus reuili''. Described by the paleontologist Fernando Novas and colleagues in 2005, it was named in honor of Pablo Puerta and Santiago Reuil, who discovered and prepared the specimen. It consists of four well-preserved vertebrae, including one cervical, one dorsal, and two caudal vertebrae. ''Puertasaurus'' is a member of Titanosauria, the dominant group of sauropods during the Cretaceous. ''Puertasaurus'' was a very large animal. Its size is difficult to estimate due to the scarcity of its remains, but current estimates place it around long and in mass. The largest of the four preserved bones is the dorsal vertebra, which at wide is the broa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
