Rebbachisaurus
''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.

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 Ameri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diplodocoidea
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. ...

Albert-Félix De Lapparent
Albert-Félix de Lapparent (1905–1975) was a French palaeontologist. He was also a Sulpician priest. He undertook a number of fossil-hunting explorations in the Sahara desert. He contributed greatly to our knowledge of dinosaurs and other prehistoric creatures. In 1986, José Bonaparte José Fernando Bonaparte (14 June 1928 – 18 February 2020) was an Argentine paleontologist who discovered a plethora of South American dinosaurs and mentored a new generation of Argentine paleontologists . One of the best-known Argentine paleo ... named the dinosaur '' Lapparentosaurus'' in his honour. Dinosaurs named by Lapparent were '' Inosaurus tedreftensis'' (Lapparent, 1960) and '' Lusitanosaurus liassicus'' (Lapparent and Zbyszewski, 1957). New species of known genera are also credited to him. In alphabetical order, they are: '' Apatosaurus alenquerensis'' (Lapparent and Zbyszewski, 1957), '' Astrodon pusillus'' (Lapparent and Zbyszewski, 1957), '' Brachiosaurus atalaiensis '' (Lappare ...

Tiourarén Formation
The Tiourarén Formation is a geological formation in the Agadez Region of Niger whose strata were originally thought to be Early Cretaceous. However, re-interpretation of the sediments showed that they are probably Middle Jurassic (Bathonian) in age.Rauhut and Lopez-Arbarello (2009).

Continental Intercalaire
The Continental intercalaire, sometimes referred to as the Continental intercalaire Formation, is a term applied to Cretaceous strata in Northern Africa. It is the largest single stratum found in Africa to date, being between thick in some places. Fossils, including dinosaurs, have been recovered from this formation. Weishampel, David B; et al. (2004). "Dinosaur distribution (Early Cretaceous, Africa)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 571-573. . The Continental intercalaire stretches from Algeria, Tunisia and Niger in the west to Egypt and Sudan in the east.

Aoufous Formation
The Aoufous Formation is a geological formation that contains some of the vertebrate assemblage of the Kem Kem Group, of Late Cretaceous date.Cavin et al., 2010, p.391Dal Sasso, C., Maganuco, S., Buffetaut, E., Mendez, M.A., 2005. New information on the skull of the enigmatic theropod ''Spinosaurus'', with remarks on its size and affinities. Journal of Vertebrate Paleontology 25 (4), 888–896. Two other formations comprise the Kem Kem beds: the underlying Ifezouane Formation and the overlying Akrabou Formation. Description The Aoufous Formation was first reported by Dubar (1948) as part of the “Sillon Preafricain”. Dubar described it from a lithological point of view as consisting mainly of clay-sandstones and green marls with gypsum. Dubar dated the sediments to the Albian / Cenomanian stages. Later, Sereno et al. (1996) reported an informal division of the Kem Kem Beds: a lower red sandstone unit ("''gres infrecenomanien''") and an upper marley unit ("''marne versicolo ...

Rayososaurus
''Rayososaurus'' is a genus of plant-eating sauropod dinosaur of the superfamily Diplodocoidea. It was found in the Candeleros Formation, but was named ''Rayososaurus'' after the Rayoso Member, which later has been elevated to the older Rayoso Formation. The formations are located in the Neuquén Basin of northern Patagonia, Argentina. ''Rayososaurus'' lived during the Cenomanian epoch of the Late Cretaceous, about 99 to 96 million years ago.L. M.

Maraapunisaurus Compar
''Maraapunisaurus'' is a genus of sauropod dinosaur from the Late Jurassic Morrison Formation of western North America. It is known only from what has sometimes been estimated to be the largest dinosaur specimen ever discovered, originally named ''Amphicoelias fragillimus''. Based on surviving descriptions of a single fossil bone, scientists have produced numerous size estimates over the years; the largest estimate ''M. fragillimus'' to have been the longest known animal at in length and with a mass of . However, because the only fossil remains were lost at some point after being studied and described in the 1870s, evidence survived only in contemporary drawings and field notes. More recent studies have made a number of suggestions regarding the possibility of such an animal. One analysis of the surviving evidence, and the biological plausibility of such a large land animal, has suggested that the enormous size of this animal were over-estimates due partly to typographical error ...
