Diplodocimorpha
Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like ''Supersaurus'', ''Diplodocus'', ''Apatosaurus'', and ''Amphicoelias''. Most had very long necks and long, whip-like tails; however, one family (the dicraeosaurids) are the only known sauropods to have re-evolved a short neck, presumably an adaptation for feeding low to the ground. This adaptation was taken to the extreme in the highly specialized sauropod ''Brachytrachelopan''. A study of snout shape and dental microwear in diplodocoids showed that the square snouts, large proportion of pits, and fine subparallel scratches in ''Apatosaurus'', ''Diplodocus'', ''Nigersaurus'', and ''Rebbachisaurus'' suggest ground-height nonselective browsing; the narrow snouts of ''Dicraeosaurus'', ''Suuwassea'', and ''Tornieria'' and the coarse scratches and gouges on the teeth of ''Dicraeosaurus'' suggest mid-height selective browsing in those taxa.John A.

Limaysaurus Tessonei
''Limaysaurus'' ("Limay lizard") is a genus represented by a single species of Rebbachisauridae, rebbachisaurid Sauropoda, sauropod dinosaurs, which lived during the mid-Cretaceous period, about 99.6 to 94 million years ago, in the Cenomanian, in what is now South America (northwestern Patagonia and northeastern Brazil). Discovery ''Limaysaurus'' includes a single type species, ''Limaysaurus tessonei'', which was originally referred to the genus ''Rebbachisaurus'' as ''Rebbachisaurus tessonei'', an African species, by Jorge O. Calvo, Jorge Calvo and Leonardo Salgado in 1995.Calvo, J. O. and Salgado, L. (1995).''Rebbachisaurus tessonei'' sp. nov. A new sauropod from the Albian-Cenomanian of Argentina; new evidence on the origin of the Diplodocidae" ''Gaia'', 11: 13-33. However, a generic separation was proposed by Salgado, Alberto Garrido (paleontologist), Alberto Garrido, Sergio Cocca and Juan Cocca, and the genus ''Limaysaurus'' was named in 2004. The generic name is derived fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplocanthosaurus Priscus
''Haplocanthosaurus'' (meaning "simple spined lizard") is a genus of diplodocoid sauropod dinosaur. Two species, ''H. delfsi'' and ''H. priscus'', are known from incomplete fossil skeletons. They lived during the Late Jurassic (Kimmeridgian stage), 155 to 152 million years ago in North America.Turner, C.E. and Peterson, F., (1999).

Amargasaurus
''Amargasaurus'' (; "La Amarga lizard") is a genus of sauropod dinosaur from the Early Cretaceous epoch (geology), epoch (129.4–122.46 Mya (unit), mya) of what is now Argentina. The only known skeleton was discovered in 1984 and is virtually complete, including a fragmentary skull, making ''Amargasaurus'' one of the best-known sauropods of its epoch. ''Amargasaurus'' was first species description, described in 1991 and contains a single known species, ''Amargasaurus cazaui''. It was a large animal, but small for a sauropod, reaching in length. Most distinctively, it sported two parallel rows of tall spines down its neck and back, taller than in any other known sauropod. In life, these spines could have stuck out of the body as solitary structures that supported a keratinous sheath. An alternate hypothesis, now more favored, postulates that they could have formed a scaffold supporting a Neural spine sail, skin sail. They might have been used for display, combat, or defense.

Diplodocus
''Diplodocus'' (, , or ) is an extinct genus of diplodocid sauropod dinosaurs known from the Late Jurassic of North America. The first fossils of ''Diplodocus'' were discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a Neo-Latin term derived from Greek διπλός (''diplos'') "double" and δοκός (''dokos'') "beam", in reference to the double-beamed chevron bones located in the underside of the tail, which were then considered unique. The genus of dinosaurs lived in what is now mid-western North America, at the end of the Jurassic period. It is one of the more common dinosaur fossils found in the middle to upper Morrison Formation, with most specimens being found in rocks between about 151.88 and 149.1 million years ago , during the latest Kimmeridgian Age, although it may have made it into the Tithonian., with at least one specimen (AMNH FR 223) being potentially from among the youngest deposits of the formation.

Cathartesaura Anaerobica
''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 laborator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limaysaurinae
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. Khebbashia is a clade within Rebbachisauridae. P. D. Mannion, P. Upchurch, D. Schwarz and O. Wings. (2019).

Zapalasaurus Bonapartei
''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 () 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. The basin bounds to the wes ..., basal diplodocoids were more diverse than previously thought." ''Zapalasaurus'' is assumed to have a long neck which would have been ...

Dicraeosaurus
''Dicraeosaurus'' (Gr. , ' "bifurcated, double-headed" + Gr. , ' "lizard") is a genus of diplodocoid sauropod dinosaur that lived in what is now Lindi Region, Tanzania during the late Jurassic period. The genus was named for the neural spines on the back of its neck. The first fossil was described by paleontologist Werner Janensch in 1914. Description Unlike most diplodocoids, ''Dicraeosaurus'' had a comparatively large head with a relatively short and wide neck. The neck contained 12 unusually short vertebral column, vertebrae, likely indicating a low-level browser of vegetation no more than off the ground. ''Dicraeosaurus'' also lacked the "whiplash" tail tip typical of diplodocoids. It was smaller than many other diplodocoids, at only in length and , though this still makes it among the larger known members of the family Dicraeosauridae. The genus is notable for the rather tall neural spines protruding from its vertebrae, which it is named for. They were not straight as in ...

Suuwassea
''Suuwassea'' is a genus of Dicraeosauridae, dicraeosaurid sauropod dinosaur found in the Upper Jurassic strata of the Morrison Formation, located in southern Carbon County, Montana, Carbon County, Montana, United States. The fossil remains were recovered in a series of expeditions during a period spanning the years 1999 and 2000 and were described by J.D. Harris and Peter Dodson in 2004. They consist of a disarticulated but associated partial skeleton, including partial vertebral series and limb bones. Etymology Since the fossil was found in an ancestral territory of the Native Americans in the United States, Native American Crow Nation, Crow tribe, the etymology of the generic name is derived from a term in Crow language, their language, ''suuwassa'', “the first thunder heard in spring”. The root ''suu'', meaning “thunder” and ''wassa'', “ancient”, are a nod to the “thunder lizard” moniker often applied to sauropods. The specific descriptor honours the deceased ...
