The continues to be of Nigersaurus were being in the beginning explained by Taquet in 1976 as belonging to the dicraeosaurid, but in 1999 Sereno and colleagues reclassified it for a rebbachisaurid diplodocoid.[four] These scientists speculated that since short necks and tiny dimensions was regarded between basal diplodocoids, it could point out these ended up ancestral characteristics of the group.
Via a painstaking course of action, this team was capable of reconstruct The within of Nigersaurus' cranium. That gave them a superb think about the lateral semicircular canal (LSC) of the interior ear, which will help animals continue to keep their balance.
Judging with the LSC orientation in Nigersaurus, Sereno and company hypothesized which the animal ordinarily walked all-around with its snout pointed to the bottom at a sixty seven-degree angle. Picture a moping teen and you will get The concept.

The dental construction of Nigersaurus delivers a must have insights in to the dietary and ecological adaptations of sauropods. Its special dental arrangement and speedy tooth substitution system highlight the numerous evolutionary procedures that dinosaurs utilized to thrive within their environments.
Like other sauropods, Nigersaurus had a long neck and tail. On the other hand, its neck was comparatively brief as compared to other users of its team, aligning with its reduced-grazing Way of living. Its columnar legs supported its quadrupedal posture and helped bear its body weight properly.
Considering that several rebbachisaurids inhabited latitudes that could have already been tropical to subtropical in the center Cretaceous, this pneumaticity might have served the animals cope With all the pretty large temperatures. In keeping with Ibiricu and colleagues, this adaptation could be a cause why rebbachisaurids ended up the only group of diplodocoids that survived into your Late Cretaceous.[21]
Nigersaurus is thought to obtain lived in what is now present day-working day Niger, Africa, therefore its title. It had been initial learned within the early 2000s by a crew of paleontologists led by Paul Sereno.

The Nigersaurus, with its amazing dental variety of five hundred slender teeth along with a wide, squared-off muzzle, serves for a remarkable window to the evolutionary paths that dinosaurs took to adapt for their environments. This specialised feeder, unlike most of its sauropod kin, evolved to snip and take in delicate, abundant vegetation near to the ground, revealing a novel market during the Cretaceous ecosystem.
The adductor muscle from the jaw seems to acquire hooked up into the quadrate instead of the supratemporal fenestra. Both of those this and one other mastication muscles were being likely weak, and Nigersaurus is believed to acquire experienced one of many weakest bites in the sauropods.[3] In addition, Based on Whitlock and colleagues in 2011, the little, almost parallel nature on the tooth scratches and pits (caused by grit, which might not be received as usually by large-browsers) show that it ate fairly soft, herbaceous vegetation such as small-rising ferns.
The limited knowledge of the genus was the results of very poor what dinosaur has 500 teeth preservation of its remains, which arises from your delicate and extremely pneumatic building (stuffed with air Areas linked to air sacs) of the skull and skeleton, consequently leading to disarticulation on the fossils. A lot of the cranium fossils were being so thin that a strong light beam was visible through them. Therefore, no intact skulls or articulated skeletons have been discovered, and these specimens signify probably the most total recognized rebbachisaurid remains.[3][one]
On the other hand, as talked about, Nigersaurus experienced a relentless supply of new teeth as they had been replaced if the leading tooth in the column wore out.
These teeth and The form in the sauropod's skull most likely evolved that will help it munch on vegetation minimal to the bottom. Grass wasn’t all over nevertheless in the course of its time, but Nigersaurus most likely spent A lot of its time grazing on a little something like it, putting on down its teeth very quickly.
