However, a more in depth paper on The full Nigersaurus skeleton came in 2007. Now, several specimens discovered by other paleontologists are underneath examination and even further details will arise as the investigation will continue.
A 2015 cladistic review by Wilsona as well as the French palaeontologist Ronan Allain discovered Rebbachisaurus itself to team with the nigersaurines, plus the authors instructed that Nigersaurinae was as a result a junior synonym of Rebbachisaurinae (considering that that name would've precedence).

The Nigersaurus roamed the lush landscapes of the middle Cretaceous period of time, in what has become the Sahara Desert of Niger. This location, as soon as teeming with life, provided a rich tapestry of sentimental, leafy vegetation which was ideal for the Nigersaurus’s specialized diet regime.
e. Apatosaurus. They also experienced predators that lived in the same location and a single of their predators was theropoda.
It lived all through a time in the event the region was covered in forests and braided rivers, and would have needed to watch out to the existence of Sarcosuchus, an enormous relative of modern crocodiles.
Nonetheless, this assert has been contested by other researchers who feel Nigersaurus was in all probability much more standard of other sauropods.
Nigersaurus experienced a jaw framework not like every other dinosaur. Its wide, squared-off muzzle housed about five hundred slender, pencil-like teeth. These teeth weren't evenly dispersed but had been organized in columns and rows, with as a lot of as nine substitution teeth guiding Each and every Lively tooth.
Nigersaurus's feeding approach was not like many other dinosaurs. Its broad, what dinosaur has 500 teeth flat jaw was tailored for grazing near the bottom, earning it the nickname "Mesozoic Cow."
Other scientists have disputed this claim, however. Reports launched in 2009 and 2013 found that the posture on the LSC can not reliably inform us what any offered sauropod's ordinary head posture appeared like. Another person demands to develop a time equipment currently.
Nigersaurus and its closest kinfolk are grouped throughout the subfamily Rebbachisaurinae (formerly considered grouped during the eponymous Nigersaurinae) from the family members Rebbachisauridae, that's Component of the sauropod superfamily Diplodocoidea. Nigersaurus was probably a browser, and fed with its head close to the bottom. The location of its Mind that detected smell was underdeveloped, although its brain dimension was similar 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 whilst there was significant correlation between the reconstructed and precise head postures, the aircraft in the semicircular canal was not held horizontally during the resting pose as inferred.
This composition was amid the initial dinosaur skulls to become digitally reconstructed making use of CT scans, supplying unprecedented insights into its feeding mechanics.
The Nigersaurus was a ground-amount browser. Its vast muzzle, combined with its several teeth, permitted it to take in substantial quantities of vegetation in just one Chunk. The orientation of its teeth, all positioned within the front of its jaws, enabled it to successfully crop and Assemble foodstuff close to the bottom.
