Working with evidence from CT scans and 3D/computer modeling, scientists have decided that the sauropod most likely habitually held its head downwards, toward the bottom — Even though this is hotly debated.
Nigersaurus likely applied its dental batteries to successfully method reduced-lying crops like ferns and horsetails, which it gathered with its broad muzzle. It possible fed at floor level due to its shorter neck, and its teeth might have worn out rapidly from shearing through hard vegetation.
Nigersaurus lived in what is currently the Sahara Desert during the mid-Cretaceous interval, somewhere around 115 to one hundred and five million several years back, in the lush, riverine habitat with plentiful flora.
Other researchers have disputed this assert, nevertheless. Experiments released in 2009 and 2013 uncovered that the posture in the LSC are not able to reliably inform us what any provided sauropod's typical head posture looked like. Anyone requirements to create a time equipment now.
Because of this as one particular tooth wore down or broke off, A different was wanting to just take its location. This rapid tooth substitution cycle, happening approximately each individual fourteen days, ensured that Nigersaurus normally had functional teeth to course of action its foods.
Sad to say, this has led to misunderstandings and occasional misuse in on-line conversations. Though the eye has sparked curiosity concerning the dinosaur, What's more, it underscores the importance of cultural sensitivity and correct interaction when speaking about scientific discoveries.
A 2015 cladistic analyze by Wilsona and also the French palaeontologist Ronan Allain identified Rebbachisaurus by itself to group Along with the nigersaurines, plus the authors suggested that Nigersaurinae was consequently a junior synonym of Rebbachisaurinae (given that that title might have precedence).
Nigersaurus is understood to obtain lived in what has become contemporary-working day Niger, Africa, as a result its name. It had been to start with identified from the early 2000s by a staff of paleontologists led by Paul Sereno.

The name "Nigersaurus" has began controversy and dialogue during the scientific community and over and above as a result of its potential for misinterpretation and unintended connotations.
Wedel and stated in 2016 that whilst sauropods normally could use their prolonged necks to detect predators from afar, this would not implement into the short-necked Nigersaurus. They pointed out that the eyes of Nigersaurus had been placed more in direction of the highest in the skull than in the majority of other sauropods, earlier mentioned the muzzle, which might give it overlapping fields of look at. Its Visible field would have been at or near 360 degrees, and hypersensitivity of motion would've been essential to a susceptible prey-animal.[twenty]
It experienced a large muzzle stuffed with a lot more than 500 teeth, which were being changed in a quick fee: close to every fourteen times. The jaws could possibly have borne a keratinous sheath. As opposed to other tetrapods, the tooth-bearing bones of its jaws have been rotated transversely relative to the remainder of the skull, so that every one of its teeth had been Positioned far on the front.
The snout was also proportionately shorter, plus the tooth row was not at all prognathous, the snout suggestion not protruding relative to the remainder of the tooth sequence.[1] Nigersaurus was unique in that its frontal bone (which fashioned A lot with the skull-roof) was elongate (Considerably narrower than extended), and experienced a marked cerebral fossa (a depression about the area of this bone Within the head).[four] The maxillary tooth row was in its entirety transversely rotated, its typical rear ninety° everted towards the front. This was matched by An analogous rotation with the dentary from the decrease jaw. This transverse orientation from the upper and decreased tooth rows was exclusive on the dinosaur. Resulting from this configuration, no other tetrapod had all 500 teeth dinosaur of its teeth Found as much to the entrance as Nigersaurus.[three][four]
