Nigersaurus and its closest family are grouped in the subfamily Rebbachisaurinae (previously considered grouped while in the eponymous Nigersaurinae) of the family members Rebbachisauridae, and that is Portion of the sauropod superfamily Diplodocoidea. Nigersaurus was likely a browser, and fed with its head near the ground. The area of its Mind that detected smell was underdeveloped, although its brain measurement was similar to that of other dinosaurs.
As we carry on to study this intriguing creature, we've been reminded with the intricate and numerous paths that evolution normally takes.
in 1999, following additional and more full remains were being observed and described. The genus identify signifies "Niger reptile", and the specific name honours the French palaeontologist Philippe Taquet, who found the initial stays.
This sauropod (long-necked dinosaur) has an uncommon skull containing as numerous as 500 slender teeth. A significant aim of this expedition is to uncover the rest of this uncommon dinosaur so we will describe it and reconstruct it for everyone to determine.
It lived for the duration of a time if the region was protected in forests and braided rivers, and might have had to watch out for the existence of Sarcosuchus, a large relative of recent crocodiles.
This sauropod (extensive-necked dinosaur) has an uncommon cranium made up of as lots of as 500 slender teeth. A significant objective of the expedition is to locate the remainder of this unusual dinosaur so we can easily describe it and reconstruct it for everybody to find out.
Sauropod dinosaurs, like Nigersaurus, walked on four legs, with a extensive “whiplash tail” and a protracted neck. But in comparison with other sauropods, it was somewhat compact — sitting somewhere concerning an African and Indian elephant in size.
Nigersaurus is very best noted for its unique skull and jaw, which contained somewhere around five hundred slender teeth organized in tightly packed rows. These teeth had been specialised for grazing on reduced-lying vegetation, earning Nigersaurus a hugely effective herbivore.
Nigersaurus also bears indications of minimal-angle tooth-to-tooth have on on The within Nigersaurus in the maxillary crowns, which implies that jaw movement was restricted to precise up-and-down motions. Worn teeth with the reduced jaw have not still been found, but they are predicted to show opposing tooth-to-tooth have on. The chance to elevate their heads nicely earlier mentioned the ground will not always imply they browsed on things there, as well as brief neck of Nigersaurus might have limited the searching vary when compared to other diplodocoids.[three]
The genus Nigersaurus was formally named in 1999 by American paleontologist Paul Sereno and his staff, pursuing the discovery of a lot more complete continues to be that allowed for a detailed description of the species.
Following the iguanodontian Lurdusaurus, Nigersaurus was probably the most various megaherbivore. Other herbivores with the exact same formation include things like Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. Collectively, these compose one of the several associations of megaherbivores having a equilibrium of sauropods and huge ornithopods.
On the basis of microtomography scans of cranium things in the holotype specimen, Sereno and colleagues developed a "prototype" Nigersaurus skull they could study. In addition they manufactured an endocast from the brain and scanned the semicircular canals of its interior ear, which they located being oriented horizontally. In their 2007 study, they mentioned the construction of the occiput in the back of the skull and cervical vertebrae would have confined the upward and downward movement of the neck and the rotation of your cranium.
