The nickname "dinosaur with five hundred teeth" arises from Nigersaurus's exclusive dental battery. Its jaw held close to five hundred slender teeth, organized in tightly packed rows, and these teeth were being frequently changed in the course of its daily life.
Only by bringing with each other vegetation from across the world and a range of modern environments can a dinosaur-age scene be recreated. A number of the plants, like ginkgos, glance almost similar to their extinct ancestors; some, like the conifer Araucaria, had been the dominant trees on the forests one hundred ten million decades ago.

It lived through a time when the area was covered in forests and braided rivers, and would have needed to watch out for the existence of Sarcosuchus, an enormous relative of recent crocodiles.
in 1999, soon after further and a lot more full stays were being discovered and explained. The genus name indicates "Niger reptile", and the particular title honours the French palaeontologist Philippe Taquet, who found out the first stays.
On the basis of microtomography scans of cranium aspects from the holotype specimen, Sereno and colleagues established a "prototype" Nigersaurus skull they might analyze. In addition they produced an endocast of the brain and scanned the semicircular canals of its interior what dinosaur has 500 teeth ear, which they observed to become oriented horizontally. Within their 2007 review, they stated the construction of the occiput behind the skull and cervical vertebrae might have minimal the upward and downward movement on the neck as well as rotation in the cranium.
In 2019, Mannion and colleagues identified that due to the fact Nigersaurus was identified to generally be the sister taxon of all other nigersaurines in a few scientific studies, a Rebbachisaurinae clade may well not automatically include Nigersaurus alone (as well as the indisputable fact that the place of Rebbachisaurus could change in long run analyses), and supported the continued use on the identify Nigersaurinae above Rebbachisaurinae for all rebbachisaurids extra closely linked to Nigersaurus than to Limaysaurus.
For instance, its fossils suggest that it had a wide, deep ribcage which will have allowed it to take in huge amounts of air, facilitating its respiratory and supplying the oxygen it needed to sustain its large system.
Nigersaurus had issue in holding their head upward or horizontally. So taking in leaves and other areas of extensive Trees was not possible for them.
The restricted knowledge of the genus was the results of very poor preservation of its remains, which occurs with the fragile and highly pneumatic construction (stuffed with air spaces linked to air sacs) of your cranium and skeleton, subsequently resulting in disarticulation of the fossils. A few of the skull fossils had been so slim that a robust light beam was seen by way of them. Thus, no intact skulls or articulated skeletons are found, and these specimens signify essentially the most comprehensive identified rebbachisaurid stays.[3][one]
Nigersaurus is thought to own lived in what is currently present day-day Niger, Africa, consequently its title. It had been very first found within the early 2000s by a group of paleontologists led by Paul Sereno.
Nigersaurus was named and explained in additional depth by Sereno and colleagues only in 1999, determined by stays of recently discovered people. The identical write-up also named Jobaria, Yet another sauropod from Niger. The genus name Nigersaurus ("Niger reptile") is a reference towards the country where it absolutely was found, and the particular name taqueti honours Taquet, who was the very first to organise large-scale palaeontological expeditions to Niger.
