Head's Up! (Maybe) Simply because Nigersaurus ate with its head down, professionals have questioned about its posture. Sereno and his co-authors as soon as argued that the herbivore aimed its deal with and neck downwards — no matter if it absolutely was feeding or not — for a subject of pattern.
Nigersaurus lived in what is currently the Sahara Desert in the course of the mid-Cretaceous time period, roughly 115 to one hundred and five million a long time ago, in a lush, riverine habitat with ample flora.
There was debate on whether or not its head was habitually held downwards, or horizontally like other sauropods. It lived in the riparian habitat, and its eating plan possibly consisted of soft crops, for example ferns, horsetails, and angiosperms. It really is Probably the most frequent fossil vertebrates located in the area, and shared its habitat with other dinosaurian megaherbivores, as well as massive theropods and crocodylomorphs.

Like other sauropods, Nigersaurus had an extended neck and tail. Nevertheless, its neck was reasonably quick in comparison to other users of its group, aligning with its very low-grazing Way of life. Its columnar legs supported its quadrupedal posture and served bear its fat efficiently.
What's much more, the same as grazing cows nowadays, these creatures were being considerable through their heyday. Following the Original discovery, Sereno observed One more Nigersaurus specimen through an expedition in 2000.
The dental constructions of Nigersaurus also recommend which they ate delicate plants in massive amounts to meet their nutritional demands. They mostly ate angiosperms, horsetails, and ferns as foodstuff. Quite a few paleontologists also believe that their 500 intently packed teeth arrangement also functioned similar to a comb. This comb-like teeth arrangement could have also assisted them in filtering and feeding on aquatic crops.
The teeth’s unique form and arrangement ended up completely suited to its feeding practices. The slender, chisel-like teeth could efficiently snip off gentle vegetation, and their immediate replacement ensured that the dinosaur could continually feed without awaiting new teeth to mature.
The skull of a Nigersaurus was manufactured from slim bones and experienced a lot of compact openings and pores. These options delivered them fantastic versatility in feeding on the ground. The muzzle in the Nigersaurus was huge and extensive which helped it in eating tiny ground-centered vegetation.
Lifetime restoration Nigersaurus 500 teeth dinosaur was distinct in that its dorsal (back again) vertebrae had paired pneumatic spaces at The bottom from the neural spines (the spines that projected upwards through the vertebrae). The presacral vertebrae (vertebrae before the sacrum) had been intensely pneumatised to the point in which the column consisted of a number of hollow "shells", each divided by a thin septum in the center. It had tiny to no cancellous bone, making the centra slim bone plates filled with air spaces. The vertebral arches have been so seriously pierced by extensions with the external air sacs that in their facet walls minimal remained but two mm (0.
This composition was among the 1st dinosaur skulls to become digitally reconstructed working with CT scans, featuring unprecedented insights into its feeding mechanics.
The sauropod dinosaur Nigersaurus likely progressed its surprisingly-shaped head to raised mow prehistoric lawns.
This revelation comes from The point that, Inspite of its elongated nostrils, the olfactory (smelling) area of its Mind was comparatively compact for its sizing. eleven. Nigersaurus could almost certainly see approximately 360 degrees when feeding
