Limb product as well as a scapula observed close by had been also referred to the exact same specimen. These fossils are housed for the Countrywide Museum of Niger.
Having said that, a more specific paper on The complete Nigersaurus skeleton came in 2007. At this time, numerous specimens learned by other paleontologists are less than assessment and more facts will arise as the analysis will keep on.
Initial discoveries of Nigersaurus fossils date again towards the nineteen sixties, nevertheless it was not till the nineteen seventies that additional complete stays ended up uncovered. These remains had been formally analyzed and explained by paleontologist Paul Sereno and his workforce in 1999.
A 2009 review with the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was capable to feed Along with the downturned head and neck posture proposed with the 2007 examine, but contested this was the habitual posture of your animal.

In 2019, Mannion and colleagues identified that considering the fact that Nigersaurus was identified for being the sister taxon of all other nigersaurines in certain studies, a Rebbachisaurinae clade may well not automatically consist of Nigersaurus itself (together with the undeniable fact that the position of Rebbachisaurus could transform in potential 500 teeth dinosaur analyses), and supported the continued use on the name Nigersaurinae around Rebbachisaurinae for all rebbachisaurids a lot more intently connected with Nigersaurus than to Limaysaurus.
lived in what is currently Niger about a hundred and fifteen to 105 million several years back, throughout the Aptian and Albian ages on the mid-Cretaceous. It probable lived in habitats dominated by inland floodplains (a riparian zone).
Quite a few Nigersaurus specimens gathered by French and American expeditions continue being being explained.[nine] Teeth comparable to Those people of Nigersaurus are located to the Isle of Wight As well as in Brazil, however it is unknown whether they belonged to family members of this taxon, or to titanosaurs, whose stays are located in the vicinity.

The Nigersaurus, with its staggering five hundred teeth, presents a fascinating distinction to its dinosaur family, Specifically other sauropods. In contrast to its cousins with less, thicker teeth, the Nigersaurus’s slender, pencil-like teeth ended up uniquely tailored for snipping smooth vegetation, a stark big difference in the robust teeth of sauropods like Brachiosaurus, which were probable created to handle more durable plants.
We are closing in on that goal speedy for the reason that we arrived on a skeleton a couple of days later on! This skeleton is lying on its side with the tail curved upward. The curve of your spine measures about fifteen ft.
Nigersaurus didn't exhibit precisely the same modifications witnessed inside the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing functions. The decrease jaw was L-shaped and divided to the subcylindrical transverse ramus, which contained the teeth, as well as the back ramus, which was additional lightweight and was The situation for the vast majority of muscle mass attachments. It was unique in which the tooth row expanded to the edges with the plane of the most crucial ramus in the decreased jaw.
