Having said that, a far more in depth paper on the whole Nigersaurus skeleton arrived in 2007. At the moment, lots of specimens uncovered by other paleontologists are under examination and even more facts will emerge since the research will go on.
It lived in the riparian habitat, and its diet plan in all probability consisted of soft vegetation, such as ferns, horsetails, and angiosperms. It is One of the more widespread fossil vertebrates found in the region, and shared its habitat with other dinosaurian megaherbivores, along with large theropods and crocodylomorphs.
Nigersaurus is believed to have lived in significant herds and could possibly have migrated above extensive distances in quest of foodstuff.
The continues to be of Nigersaurus were originally explained by Taquet in 1976 as belonging into a dicraeosaurid, but in 1999 Sereno and colleagues reclassified it like a rebbachisaurid diplodocoid.[four] These scientists speculated that considering the fact that limited necks and small dimensions was recognised among the basal diplodocoids, it may well indicate these were being ancestral features of the team.
Nigersaurus is believed to behave very like other herbivore sauropods. They had likely invested most in their time in cling-Pet dog positions and grazing lower-lying vegetation.
” Our first week in the field continues to be magnificent! Outstanding discoveries appear to be watching for us close to every dune. On our 1st day, we uncovered bones with the very long-necked dinosaur Nigersaurus. Nigersaurus, you may perhaps try to remember, we named for bones gathered on the final expedition below a few yrs in the past.
Nigersaurus was named after the West African state in which its fossils were being found: the Republic of Niger. All through this creature’s time, the landscape (now Component of the Sahara Desert) is believed to are coated with forests and braided rivers.
Nigersaurus also bears signs of lower-angle tooth-to-tooth don on The within on the maxillary crowns, which indicates that jaw motion was restricted to precise up-and-down motions. Worn teeth through the lower jaw have not still been discovered, but They are really expected to show opposing tooth-to-tooth use. A chance to increase their heads effectively over the bottom doesn't always imply they browsed on goods there, and the small neck of Nigersaurus would have restricted the browsing variety in comparison with other diplodocoids.[3]
It experienced a large muzzle filled with much more than 500 teeth, which were changed at a rapid level: all around each fourteen days. The jaws may have borne a keratinous sheath. Contrary to other tetrapods, the tooth-bearing bones of its jaws were rotated transversely relative to the remainder of the skull, so that each one of its teeth had been Situated far on the front.

Nigersaurus and its closest relations are grouped inside the subfamily Rebbachisaurinae (formerly considered grouped in the eponymous Nigersaurinae) on the loved ones what dinosaur has 500 teeth Rebbachisauridae, which is Portion of the sauropod superfamily Diplodocoidea. Nigersaurus was possibly a browser, and fed with its head near the ground. The area of its Mind that detected smell was underdeveloped, Though its brain dimensions was comparable to that of other dinosaurs.
Feeding on like that can be tough in your dental well being Unless of course you have a syteady offer of alternative teeth. Nigersaurus have to have worn out its tooth crowns in a rapid-fireplace rate.
The dinosaur's vertebrae was stuffed with air pockets similar to These of birds, Hence the dinosaur was likely rather mild, in addition. Its brain was with regard to the measurement of the walnut, that's kind of common for sauropods, Sereno suggests.
Its brief neck would have also been an adaptation to this floor-amount feeding habits, as it would not have been in a position to reach substantial into trees like Various other sauropods.
