Nigersaurus and its closest family are grouped within the subfamily Rebbachisaurinae (previously thought to be grouped while in the eponymous Nigersaurinae) of your spouse and children Rebbachisauridae, which can be Element of the sauropod superfamily Diplodocoidea. Nigersaurus was likely a browser, and fed with its head near to the ground. The region of its Mind that detected smell was underdeveloped, Despite the fact that its Mind dimension was akin to that of other dinosaurs.
By way of a painstaking method, this crew was able to reconstruct The within of Nigersaurus' cranium. That gave them a very good consider the lateral semicircular canal (LSC) in the inner ear, which helps animals hold their harmony.
Judging from the LSC orientation in Nigersaurus, Sereno and firm hypothesized which the animal usually walked around with its snout pointed to the bottom at a 67-degree angle. Picture a moping teenager and you will get The thought.
It really is thought that these sauropod dinosaurs gathered food stuff employing their large, wide mouths, similar to grazing in modern-day cows. They would possible have already been “nonselective” of their diet program. two. Nigersaurus was one of the 1st dinosaurs to get a CT scan

As we’ve viewed, Nigersaurus experienced a large muzzle and numerous teeth completely suited for consuming reduced-lying plants. This diet and lifestyle might have essential the creature to have a regular source of replacement teeth, as it might have worn out its tooth crowns swiftly. A research published in the journal PLOS One
Though other heavy animals examined (for example rhinoceroses) experienced thick and variable bone cortices, the cortex of Nigersaurus was relatively slender. These scientists proposed that the microanatomy of sauropods was not influenced by drastic selective pressure brought on by bearing fat, but that options including the columnar limbs (as found in elephants), pneumaticity, and fleshy foot pads and cartilage peaceful strain about the bones. They also instructed that sauropods may perhaps as a result are actually lighter in pounds than expected for his or her dimensions, supporting the lowest overall body mass estimates for these dinosaurs.[22]
Having said that, this declare has been contested by other researchers who feel Nigersaurus was most likely far more usual of other sauropods.
The authors for that reason cautioned towards using semicircular canals as proxy to infer the precise orientation of skulls. They found that diet correlated strongly with semicircular canal orientation, but not with head posture, while head posture and semicircular canal orientation were being strongly correlated with phylogeny.[twenty five]
The Nigersaurus is a captivating and exclusive dinosaur which includes captured popular attention, partly because of its unconventional features and intriguing nickname since the "dinosaur with 500 teeth."
What dinosaur has five hundred teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert one hundred ten million many years back. These sauropod dinosaurs gathered food stuff that has a huge, wide mouth; the snout was wider than the back again from the creature's head on the first fossil skull.
Nigersaurus is thought from numerous partial skeletons and isolated bones, which have provided precious information about its anatomy and actions.
We have an interest find extra than simply dinosaurs. We wish to find all animals and plants that once lived along The traditional streams and forests 110 million many years in the past. One of the more prevalent fossils we encountered in the first week of work belonged to Nigersaurus an enormous crocodile known as Sarcosuchus.
