Rebbachisaurinae
Rebbachisaurinae is a subfamily within the family Rebbachisauridae, defined to include '' Rebbachisaurus garasbae'' and exclude ''Limaysaurus tessonei''. It was first proposed as a rank by Jose Bonaparte in 1995, to include ''Rebbachisaurus''. Some phylogenies however, include ''Rebbachisaurus'' in a clade with ''Limaysaurus'', and thus the subfamily was not used. In 2015, a phylogenetic analysis was conducted, and it found ''Rebbachisaurus'' instead to be closer to ''Nigersaurus ''Nigersaurus'' is a genus of rebbachisaurid sauropod dinosaur that lived during the middle Cretaceous period, about 115 to 105 million years ago.

Nigersaurus
''Nigersaurus'' is a genus of rebbachisaurid sauropod dinosaur that lived during the middle Cretaceous period, about 115 to 105 million years ago. It was discovered in the Elrhaz Formation in an area called Gadoufaoua, in Niger. Fossils of this dinosaur were first described in 1976, but it was only named ''Nigersaurus taqueti'' in 1999, after further and more complete remains were found and described. The genus name means "Niger reptile", and the specific name honours the palaeontologist Philippe Taquet, who discovered the first remains. Small for a sauropod, ''Nigersaurus'' was about long, and had a short neck. It weighed around , comparable to a modern elephant. Its skull was very specialised for feeding, with large fenestrae and thin bones. It had a wide muzzle filled with more than 500 teeth, which were replaced at a rapid rate: around every 14 days. The jaws may have borne a keratinous sheath. Unlike other tetrapods, the tooth-bearing bones of its jaws were rotated tra ...

Tataouinea
''Tataouinea'' is an extinct genus of sauropod dinosaur in the subfamily Rebbachisaurinae of Rebbachisauridae which lived in the Early Cretaceous of Tunisia. Only one species, ''T. hannibalis'', is known. Discovery and naming The first known elements of the holotype were discovered in the Aïn el Guettar Formation in 2011 by Aldo Luigi Bacchetta, but he was unable to excavate the specimen until 2012. The remains were subsequently studied by Federico Fanti, Andrea Cau, Mohsen Hassine and Michela Contessi. The genus was named in 2013. The name refers to the Tataouine Governatorate, Tunisia, and Hannibal. In 2015 more material of the holotype specimen was uncovered after the initial description were analysed. These included additional tail vertebrae. Description Its bones were extensively pneumatic, providing strong support for the theory that sauropods had birdlike respiratory systems. Key characteristics of its vertebral morphology show that ''Tatouinea'' was a rebbac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rebbachisaurus Garasbae
''Rebbachisaurus'' (meaning " Aït Rebbach lizard") is a genus of sauropod dinosaur of the superfamily Diplodocoidea, that lived during the Late Cretaceous period in Africa and possibly also South America about 99-97 million years ago. Remains attributed to ''Rebbachisaurus'' have been found in Morocco, Niger, Algeria, Tunisia and possibly also Argentina (if ''Rayososaurus'' is the same animal as ''Rebbachisaurus''), although only the Moroccan remains can be referred to the genus without doubt. The discovery of ''Rayososaurus'', a South American sauropod nearly identical to ''Rebbachisaurus'' which may have actually have been the same animal as ''Rebbachisaurus'', supports the theory that there was still a land connection between Africa and South America during the Early Cretaceous, long after it was commonly thought the two continents had separated.Bonaparte, J.

Rebbachisaurids
Rebbachisauridae is a family of sauropod dinosaurs known from fragmentary fossil remains from the Cretaceous of South America, Africa, North America, Europe and possibly Central Asia. Taxonomy In 1990 sauropod specialist Jack McIntosh included the first known rebbachisaurid genus, the giant North African sauropod ''Rebbachisaurus'', in the family Diplodocidae, subfamily Dicraeosaurinae, on the basis of skeletal details. With the discovery in subsequent years of a number of additional genera, it was realised that ''Rebbachisaurus'' and its relatives constituted a distinct group of dinosaurs. In 1997 the Argentine paleontologist José Bonaparte described the family Rebbachisauridae, and in 2011 Whitlock defined two new subfamilies within the group: Nigersaurinae and Limaysaurinae. The cladogram of the Rebbachisauridae according to Carballido ''et al.'' (2012) is shown below: Cladogram after Fanti ''et al.'', 2015. Evolutionary relationships and characteristics Although al ...

Comahuesaurus
''Comahuesaurus'' (meaning "Comahue lizard") is a genus of sauropod dinosaur of the family Rebbachisauridae. It was found in the Lohan Cura Formation, in Argentina and lived during the Early Cretaceous, Aptian to Albian. The type species is ''C. windhauseni'', named by Carballido and colleagues in 2012. It had originally been assigned to ''Limaysaurus'' by Salgado ''et al.'' (2004), but was later assigned its own genus based on the presence of diagnostic characters in the caudal centra, pubis and ischium. ''Comahuesaurus'' is known from abundant material compared to other rebbachisaurids; 37 caudal vertebrae, three fragmentary dorsal vertebrae and multiple appendicular elements, including a right humerus, pubis, ischium and a 113 cm long left femur. In their phylogenetic analysis, Carballido ''et al.'' (2012) placed ''Comahuesaurus'' in an intermediate position between basal rebbachisaurids such as '' Histriasaurus'' and the derived clade formed by subfamilies Rebbachisaurin ...

Zapalasaurus
''Zapalasaurus'' is a genus of sauropod dinosaur described by Leonardo Salgado, Ismar de Souza Carvalho and Alberto Garrido in 2006. It was named after the city of Zapala, which is approximately away from where the holotype was discovered. The type species, ''Zapalasaurus bonapartei'', was found in the La Amarga Formation of the Neuquén Basin, Neuquén Province, Argentina. It was a diplodocoid, a long-necked herbivore, and it lived during the Early Cretaceous. The authors conclude from examining the skeleton that "The record of ''Zapalasaurus bonapartei'' shows that, at least in the Neuquén Basin Neuquén Basin ( es, Cuenca Neuquina) is a sedimentary basin covering most of Neuquén Province in Argentina. The basin originated in the Jurassic and developed through alternating continental and marine conditions well into the Tertiary.

Limaysaurus
''Limaysaurus'' ("Limay lizard") is a genus represented by a single species of rebbachisaurid sauropod dinosaurs, which lived during the mid-Cretaceous period, about 99.6 to 97 million years ago, in the Cenomanian, in what is now South America (northwestern Patagonia). Description ''Limaysaurus'' was a medium-sized sauropod. Gregory S. Paul in 2010 estimated its length at fifteen meters (50 ft) and its weight at seven tonnes.Paul, G.S., 2010, ''The Princeton Field Guide to Dinosaurs'', Princeton University Press, pp. 186 and 208. The neural spines on its back were very tall. The neural spines of the cervical and dorsal vertebrae are not V-shaped but they have a simple and straight form like an I. Its teeth were curved, unlike those of ''Diplodocus'' which were pencil-shaped. Another distinct characteristic of this sauropod is its phylogenetic relationship to ''Rebbachisaurus'' from Morocco. This discovery supports the theory that there was a land bridge connecting South America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathartesaura
''Cathartesaura'' is a genus of rebbachisaurid sauropod dinosaur hailing from the Late Cretaceous strata of the Huincul Formation, at the "La Buitrera" locality, in the Neuquén Basin of Río Negro Province, Argentina. The fossil remains, described by Gallina and Apesteguía in 2005, consist of a partial skeleton including vertebrae and limb bones. These were found at the base of the formation, which spans the Cenomanian and Coniacian epochs, in mudstone and sandstone levels. Etymology The generic name is composed of ''Cathartes'', the New World vulture genus and ''-saura'', feminine declination of the Greek term ''sauros'', "lizard". It also implies the juxtaposition of the components of the scientific name of the turkey vulture, ''Cathartes aura'', whose Spanish name, "''buitre''", named the locality where the fossil was found due to the abundance of such birds there. The specific epithet honors the Argentinian adhesive company Anaeróbicos for providing field and laboratory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
