Eventually, back again in the lab, Sereno needed to ask for a second impression from colleagues who worked on fossil fish and other reptiles ahead of he figured it out.
Head's Up! (It's possible) Due to the fact Nigersaurus ate with its head down, professionals have questioned about its posture. Sereno and his co-authors after argued which the herbivore aimed its facial area and neck downwards — whether it had been feeding or not — as being a issue of routine.
Fossils of this dinosaur had been to start with described in 1976, but it absolutely was only named Nigersaurus taqueti in 1999, right after further more and even more finish remains ended up discovered and explained. The genus title means "Niger reptile", and the precise title honours the palaeontologist Philippe Taquet, who found out the primary remains.
This sauropod (extended-necked dinosaur) has an abnormal skull containing as a lot of as five hundred slender teeth. An important intention of this expedition is to find the rest of this strange dinosaur so we are able to explain it and reconstruct it for everybody to check out.
If accurate, it could starkly contrast with most sauropod reconstructions, exhibiting the animal Keeping its head horizontally.
This intriguing variation showcases the diverse methods dinosaurs designed to prosper in their environments. The Nigersaurus’s swift tooth alternative, occurring just about every fourteen times, is additionally exceptional, placing it besides other sauropods that experienced slower tooth turnover.
Sauropod dinosaurs, like Nigersaurus, walked on 4 legs, by using a long “whiplash tail” and an extended neck. But as compared to other sauropods, it was fairly compact — sitting somewhere involving an African and Indian elephant in sizing.
The secret lies while in the creature’s bones. Experts might have uncovered far more Nigersaurus fossils Should the animal had not experienced such a fragile bone composition. In line with a analyze by Sereno et al. 2007, this creature had an exceptionally light-weight cranium. Most of the bones in Nigersaurus
Many Nigersaurus specimens collected by French and American expeditions continue to be being explained.[9] Teeth much like People of Nigersaurus happen to be observed on the Isle of Wight and in Brazil, but it is not known whether or not they belonged to family of the taxon, or to titanosaurs, whose stays have been located in the vicinity.
Nigersaurus is really a genus of sauropod dinosaurs that lived somewhere around a hundred and fifteen to a hundred and five million a long time back over the Early to Mid-Cretaceous time period. It belonged towards the rebbachisaurids, a subgroup of Diplodocoidea, a clade of very long-necked, herbivorous dinosaurs.

There have been lots of mild, aerated bones — generally related to theropods, like Tyrannosaurus rex, and the birds that evolved from them — And so the researchers assumed that was what they were dealing with.
Nigersaurus was named and explained in additional detail by Sereno and colleagues only in 1999, determined by remains of recently observed people. The identical short article also named Jobaria, another sauropod from Niger. The genus title Nigersaurus ("Niger reptile") can be a reference into the nation the place it absolutely was discovered, and the specific title taqueti honours Taquet, who was the very first to organise big-scale palaeontological expeditions to Niger.
The fragile character with the Nigersaurus’s slender teeth and fragile skull produced excavation and preservation specifically tricky. Nonetheless, these challenges had been satisfied with impressive procedures in fossil Restoration and 3D reconstruction, allowing for scientists to piece together the intricate particulars of its jaw as well as the astonishing variety of Nigersaurus five hundred teeth.
