Following the iguanodontian Lurdusaurus, Nigersaurus was by far the most many megaherbivore. Other herbivores through the same development contain Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. Collectively, these compose one of many number of associations of megaherbivores that has a equilibrium of sauropods and enormous ornithopods.
Due to the fact a number of rebbachisaurids inhabited latitudes that would happen to be tropical to subtropical in the Middle Cretaceous, this pneumaticity could possibly have helped the animals cope With all the extremely higher temperatures. In keeping with Ibiricu and colleagues, this adaptation may be a explanation why rebbachisaurids have been the one team of diplodocoids that survived into your Late Cretaceous.[21]
In general, Nigersaurus was a unique and weird dinosaur as a consequence of its dental batteries and huge muzzle, which permitted it to effectively procedure and Assemble plant substance. Its small sizing and herbivorous eating plan ensure it is an interesting distinction on the larger, carnivorous dinosaurs that happen to be more generally recognised to most people.
In comparison, Nigersaurus was around the tiny side. What caught All people's consideration was the dinosaur's mug.
There have been debate on no matter whether its head was habitually held downwards, or horizontally like other sauropods. It lived in a riparian habitat, and its diet regime almost certainly consisted of sentimental crops, including ferns, horsetails, and angiosperms. It is one of the most prevalent fossil vertebrates identified in the area, and shared its habitat with other dinosaurian megaherbivores, in addition to huge theropods and crocodylomorphs.
These teeth and the shape on the sauropod's skull possible evolved to help it munch on vegetation reduced to the ground. Grass wasn’t all around nevertheless all through its time, but Nigersaurus most likely put in much of its time grazing on one thing like it, wearing down its teeth very quickly.
After the iguanodontian Lurdusaurus, Nigersaurus was quite possibly the most quite a few megaherbivore. Other herbivores in the similar formation involve Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. With each other, these compose one of the number of associations of megaherbivores with a equilibrium of sauropods and large ornithopods.
This rapid tooth replacement, with new teeth rising each individual fourteen times, ensured it preserved sharp edges for grazing on soft vegetation. The exceptional dental arrangement manufactured it hugely effective at processing lower-lying crops, contributing to its name as a specialised herbivore.
The Nigersaurus, with its remarkable dental variety of five hundred slender teeth in addition to a wide, squared-off muzzle, serves as a outstanding window in to the evolutionary paths that dinosaurs 500 teeth dinosaur took to adapt to their environments. This specialised feeder, compared with a lot of its sauropod family members, developed to snip and take in smooth, abundant vegetation close to the ground, revealing a singular specialized niche in the Cretaceous ecosystem.

This framework was amid the very first dinosaur skulls being digitally reconstructed employing CT scans, supplying unprecedented insights into its feeding mechanics.
In 2017, the Argentinian palaeontologist Lucio M. Ibiricu and colleagues examined the postcranial skeletal pneumaticity from the skeletons of rebbachisaurids, and instructed that it absolutely was an adaptation for decreasing the density of your skeleton, and this could have lowered the muscle Power needed to shift your body, in addition to the warmth produced in the procedure.
