The Air Obvious Nigersaurus stayed underneath the radar for fairly a while. The main acknowledged fossils belonging to this animal had been recovered in the 1950s by French paleontologists within the Nigerian Sahara. Regretably, These types of bones were being isolated or fragmentary.
Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is a genus of rebbachisaurid sauropod dinosaur that lived through the middle Cretaceous period, about a hundred and fifteen to a hundred and five million decades ago. It was identified within the Elrhaz Development in a region called Gadoufaoua, in Niger.
Continual Tooth Substitute: Teeth ended up replaced each and every fourteen times, ensuring a pointy, useful dental battery to manage with continual don from grazing.

What dinosaur has 500 teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert 110 million years back. These sauropod dinosaurs collected food items which has a massive, wide mouth; the snout was broader than the back with the creature's head on the first fossil skull.
Sauropod dinosaurs, like Nigersaurus, walked on four legs, using a lengthy “whiplash tail” and a long neck. But in comparison to other sauropods, it was relatively small — sitting down somewhere concerning an African and Indian elephant in dimensions.
in 1999, soon after further more and much more comprehensive continues to be were being found and described. The genus name indicates "Niger reptile", and the particular title honours the French palaeontologist Philippe Taquet, who learned the main continues to be.

Nigersaurus's feeding system was compared with many other dinosaurs. Its broad, flat jaw was adapted for grazing near the bottom, earning it the nickname "Mesozoic Cow."
Nigersaurus is most effective noted for its unique cranium and jaw, which contained approximately 500 slender teeth organized in tightly packed rows. These teeth were specialized for grazing on low-lying vegetation, building Nigersaurus a very economical herbivore.
Teeth at diverse development levels, Museo di Storia Naturale di Venezia The slender teeth had marginally curved tooth crowns, which had been oval in cross-section. The crowns ended up distinct in obtaining notable ridges over the margins of their midline and sides. The teeth inside the reduce jaw may perhaps have already been twenty–30% lesser than Individuals from the upper jaw, but several are recognized, and they're of uncertain maturity. Other than this, the teeth were similar.[four] Less than Every single active tooth there was a column of 9 substitution teeth inside the jaw.
The swift tooth alternative implies that it principally fed on delicate, abrasive plants, which might wear down its teeth quickly.
Dental batteries are a singular adaptation present in some plant-feeding on dinosaurs that permitted them to efficiently course of action hard vegetation. These batteries encompass vertically stacked columns of teeth, Along with the leading tooth in Each individual column being changed since it wears out.
The authors for that reason cautioned versus using semicircular canals as proxy to infer the precise orientation of skulls. They identified that diet regime correlated strongly with semicircular canal orientation, although not with head what dinosaur has 500 teeth posture, though head posture and semicircular canal orientation were strongly correlated with phylogeny.[25]
