Making use of evidence from CT scans and 3D/Laptop modeling, researchers have decided that the sauropod likely habitually held its head downwards, toward the bottom — although This is certainly hotly debated.
Head's Up! (Possibly) Mainly because Nigersaurus ate with its head down, industry experts have puzzled about its posture. Sereno and his co-authors once argued that the herbivore aimed its deal with and neck downwards — whether it had been feeding or not — like a subject of pattern.
Judging because of the LSC orientation in Nigersaurus, Sereno and corporation hypothesized that the animal ordinarily walked all over with its snout pointed to the ground in a 67-diploma angle. Photo a moping teen and you will get The concept.
It truly is thought that these sauropod dinosaurs gathered meals utilizing their major, broad mouths, just like grazing in modern cows. They'd likely happen to be “nonselective” in their food plan. 2. Nigersaurus was on the list of very first dinosaurs to acquire a CT scan
On The idea of microtomography scans of skull elements of your holotype specimen, Sereno and colleagues made a "prototype" Nigersaurus cranium they could take a look at. In addition they built an endocast with the Mind and scanned the semicircular canals of its inner ear, which they found to generally be oriented horizontally. Inside their 2007 review, they stated which the structure with the occiput at the back of the cranium and cervical vertebrae might have limited the upward and downward motion of your neck and the rotation on the cranium.
Teeth at different expansion levels, Museo di Storia Naturale di Venezia The slender teeth experienced somewhat curved tooth crowns, which were oval in cross-section. The crowns had been distinctive in acquiring popular what dinosaur has 500 teeth ridges within the margins in their midline and sides. The teeth within the lessen jaw could have been 20–thirty% smaller than All those in the higher jaw, but several are regarded, and they are of unsure maturity. Apart from this, the teeth had been equivalent.[4] Below Every single Lively tooth there was a column of nine alternative teeth throughout the jaw.
It absolutely was identified inside the loaded fossil vertebrate fauna in the Elrhaz Development in a place identified as Gadoufaoua, inside the Republic of Niger. Fossils of the dinosaur had been initially described in 1976, but it was only named in 1999 immediately after more full continues to be had been identified and explained.
Nigersaurus is best recognized for its distinctive cranium and jaw, which contained approximately five hundred slender teeth arranged in tightly packed rows. These teeth ended up specialised for grazing on low-lying vegetation, earning Nigersaurus a remarkably effective herbivore.
As it had been a prey animal, it had been very important for Nigersaurus to have movement hypersensitivity to detect any prospective threats.
Nigersaurus was named once the West African nation wherever its fossils have been identified: The Republic of Niger. Back again when this animal roamed, forests and braided rivers protected the landscape. (Nigersaurus would've needed to Be careful for Sarcosuchus, a big relative of modern crocodiles.)

What dinosaur has 500 teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert a hundred and ten million decades back. These sauropod dinosaurs gathered food stuff that has a massive, broad mouth; the snout was wider in comparison to the back of the creature's head on the first fossil skull.
Nigersaurus is thought from a number of partial skeletons and isolated bones, which have delivered worthwhile information regarding its anatomy and behavior.
In conclusion, Nigersaurus was a novel and appealing dinosaur that lived during the Late Cretaceous interval in what is currently Niger. Its rows of tiny teeth and specialised jaw construction built it properly-fitted to searching on minimal-lying vegetation, and its fossils function a worthwhile source of specifics of the diversity of lifestyle that existed on this planet many a long time ago.
