That large muzzle with its Nigersaurus teeth was perfect for scooping up ferns, horsetails as well as other minimal-lying crops. And With all the bountiful teeth, the dinosaur would've had no difficulties shearing by way of this vegetation.
On the other hand, a far more detailed paper on The entire Nigersaurus skeleton arrived in 2007. Currently, several specimens found out by other paleontologists are below evaluation and further more particulars will emerge as the exploration will continue.
Its feeding model continues to be compared to that of modern grazing animals or perhaps a vacuum cleaner, as it probable swept its head side-to-aspect though consuming vegetation.

The dental construction of Nigersaurus delivers a must have insights in the dietary and ecological adaptations of sauropods. Its distinctive dental arrangement and fast tooth alternative mechanism spotlight the assorted evolutionary techniques that dinosaurs used to prosper in their environments.
Inspite of its smaller sized dimensions, Nigersaurus is notable for its exclusive adaptations, particularly its specialized teeth and feeding mechanisms, which distinguish it in paleontological scientific tests.
Nigersaurus's feeding system was as opposed to all kinds of other dinosaurs. Its broad, flat jaw was tailored for grazing near to the ground, earning it the nickname "Mesozoic Cow."
The Nigersaurus was a floor-amount browser. Its large muzzle, combined with its many teeth, permitted it to take in big quantities of vegetation in one Chunk. The orientation of its teeth, all positioned for the entrance of its jaws, enabled it to properly crop and Obtain foods close to the bottom.
The adductor muscle from the jaw seems to have hooked up towards the quadrate in lieu of the supratemporal fenestra. Both of those this and another mastication muscles had been very likely weak, and Nigersaurus is estimated to have had one of the weakest bites with the sauropods.[3] In addition, In keeping with Whitlock and colleagues in 2011, the compact, virtually parallel character on the tooth scratches and pits (a result of grit, which might not be obtained as typically by high-browsers) reveal that it ate fairly smooth, herbaceous crops which include low-increasing ferns.
Nigersaurus was named once the West African country wherever its fossils had been learned: the Republic of Niger. For the duration of this creature’s time, the landscape (now A part of the Sahara Desert) is considered to are already coated with forests and braided rivers.
Daily life restoration Nigersaurus was distinctive in that its dorsal (back again) vertebrae had paired pneumatic spaces at The bottom from the neural spines (the spines that projected upwards from the vertebrae). The presacral vertebrae (vertebrae before the sacrum) ended up seriously pneumatised to The purpose exactly where the column consisted of a number of hollow "shells", Every single divided by a what dinosaur has 500 teeth thin septum in the center. It had tiny to no cancellous bone, creating the centra slender bone plates crammed with air Areas. The vertebral arches were being so intensely pierced by extensions from the exterior air sacs that in their side partitions small remained but two mm (0.

Nigersaurus is understood from quite a few partial skeletons and isolated bones, that have offered valuable information about its anatomy and behavior.
It even more argued which the orientation in the semicircular canals may differ drastically in just present day species, and it is for that reason not responsible for deciding head posture.[23] This was supported by the Spanish palaeontologist Jesús Marugán-Lobón and colleagues in a 2013 analyze that instructed the procedures used by Sereno's crew have been imprecise, Which Nigersaurus habitually held its head like other sauropods.[24]
