Drusilasaura
''Drusilasaura'' is an extinct genus of possible lognkosaurian titanosaur sauropod dinosaur which lived during the late Cretaceous (Cenomanian-Turonian stage) of Santa Cruz Province of southern Patagonia, Argentina. ''Drusilasaura'' is known from the holotype MPM-PV 2097/1 to 2097/19, a partial skeleton including four dorsal vertebrae, a sacral vertebra, six caudal vertebrae, a left scapula, dorsal rib fragments and other fragments. It was found by palaeontologist Marcelo Tejedor searching fossil mammals, in layers of the Upper Member of the Bajo Barreal Formation, on the María Aike Ranch owned by the Ortiz de Zárate family. A team from the '' Laboratorio de Paleontología de Vertebrados'' of the ''Universidad Nacional de la Patagonia San Juan Bosco'' subsequently collected the remains.Navarrete, C.; Casal, G. & Martínez, R., (2008), "Nuevos materiales de Titanosauridae (Lognkosauria?) de la Formación Bajo Barreal, Cretácico Superior, Santa Cruz, Argentina".

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] |
Bajo Barreal Formation
The Bajo Barreal Formation is a geological formation in the Golfo San Jorge Basin of Chubut and Santa Cruz, Argentina whose strata date back to the Middle Cenomanian to Late Turonian. The formation was first described by Teruggi & Rossetto in 1963.Casal et al., 2016, p.55 The sandstones, claystones, mudstones, conglomerates and tuff were deposited in a fluvial environment. The upper part of formation is laterally equivalent to the Yacimiento El Trébol and Meseta Espinosa Formation and the lower part to the Laguna Palacios, Cañadón Seco and Comodoro Rivadavia Formations. The Bajo Barreal Formation is a reservoir rock in the Golfo San Jorge Basin.Sywan, 2001, p.131 Vertebrate paleofauna Dinosaurs Indeterminate abelisauroids and titanosaurs have been recovered from the formation ;Other fossils Other fossils found in the formation include:Casal, 2016, p.58 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Upper 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 Anta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapula
The scapula (plural scapulae or scapulas), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other. The name derives from the Classical Latin word for trowel or small shovel, which it was thought to resemble. In compound terms, the prefix omo- is used for the shoulder blade in medical terminology. This prefix is derived from ὦμος (ōmos), the Ancient Greek word for shoulder, and is cognate with the Latin , which in Latin signifies either the shoulder or the upper arm bone. The scapula forms the back of the shoulder girdle. In humans, it is a flat bone, roughly triangular in shape, placed on a posterolateral aspect of the thoracic cage. Structure The scapula is a thick, flat bone lying on the thoracic wall that provides an attachment for three groups of muscles: intrin ...

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 ...

Río Deseado
Deseado River () is a river in the Argentine province of Santa Cruz. The name Deseado comes from the English ''Desire'', the name of one of the two ships commanded by John Davis during the Thomas Cavendish expedition of 1592. The source of the river is located as the Fénix River some kilometers north of the Buenos Aires Lake in the northwestern part of the province at the Andes range. Originally, if then flowed into the lake (and the via Rio Baker into the Pacific). In 1898, a canal was built that turned it into today's Rio Deseado, flowing for before reaching the Atlantic Coast. On its way southeast, its water is tapped for irrigation. Its tributaries include the Pinturas River. The river sometimes disappears under the arid terrain, to re-emerge before reaching Puerto Deseado Puerto Deseado, originally called Port Desire, is a city of about 15,000 inhabitants and a fishing port in Patagonia in Santa Cruz Province of Argentina, on the estuary of the Deseado River.

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

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.
