As it was a prey animal, it absolutely was critical for Nigersaurus to possess movement hypersensitivity to detect any likely threats.
It lived inside of a riparian habitat, and its diet regime most likely consisted of soft vegetation, for example ferns, horsetails, and angiosperms. It really is The most prevalent fossil vertebrates identified in the region, and shared its habitat with other dinosaurian megaherbivores, along with significant theropods and crocodylomorphs.
Nigersaurus is thought to get lived in big herds and could possibly have migrated above extended distances in quest of meals.
The authors for that reason cautioned towards employing semicircular canals as proxy to infer the specific orientation of skulls. They identified that diet correlated strongly with semicircular canal orientation, although not with head posture, although head posture and semicircular canal orientation had been strongly correlated with phylogeny.[twenty five]
The Nigersaurus had really extended neck. It had been about 2 times the size of its system. This adaptation is assumed to obtain evolved as a way to make it possible for Nigersaurus to reach larger amounts of vegetation. Nigersaurus also experienced a very smaller head. It measured only about thirty centimetres (12 inches) in width.
These teeth and The form from the sauropod's skull most likely developed to help it munch on plants very low to the ground. Grass wasn’t around nonetheless in the course of its time, but Nigersaurus possibly put in A great deal of its time grazing on a little something like it, sporting down its teeth very quickly.
Judging through the LSC orientation in Nigersaurus, Sereno and organization hypothesized which the animal usually walked all over with its snout pointed to the bottom at a sixty seven-diploma angle. Photo a moping teen and you'll get the idea.

These well known dinosaur reconstructions within the nineteen sixties are no longer scientifically precise. Can you see the glitches?
It had all over 500 slim teeth in its jaw which were replaced with new teeth in 2 weeks. Its higher jaw teeth had been more substantial than its lower jaw teeth. In addition, Its jaw was Considerably wider in comparison to the skull.
Nigersaurus and its closest kinfolk are grouped inside the subfamily Rebbachisaurinae (previously considered grouped during the eponymous Nigersaurinae) in the household Rebbachisauridae, which is Portion of the sauropod superfamily Diplodocoidea. Nigersaurus was almost certainly a browser, and fed with its head near to the bottom. The location of its brain that detected scent was underdeveloped, Despite the fact that its brain sizing was comparable to that of other dinosaurs.
In 2020, the French palaeontologist Julien Benoit and colleagues analyzed lateral semicircular canal correlation to move posture on present day mammals, and found that while there was major correlation amongst the reconstructed and true head postures, the plane of your semicircular canal wasn't held horizontally inside the resting pose as inferred.
