Nigersaurus had a outstanding dental battery consisting of somewhere around five hundred slim, intently packed teeth, arranged in rows along its huge, flat jaw.

All of the tooth columns in Nigersaurus' dental batteries were lined up, compared with the teeth of other dinosaurs, at the extremely entrance of its mouth, positioned together the muzzle's gently curved periphery.

Nigersaurus had about 500 teeth arranged in dental batteries (rows of teeth stacked upon other rows of teeth), which permitted it to successfully graze on small-lying vegetation like ferns and horsetails. Worn teeth were continually replaced to keep up Niversaurus' successful feeding.

Even with its limited head and small neck, it had a protracted tail and teeth that were adapted for grazing on vegetation. Nigersaurus is believed to are a quadrupedal herbivore and might have fed on soft plants working with its extensive neck and a small head.

Nigersaurus was named once the West African state the place its fossils had been identified: the Republic of Niger. During this creature’s time, the landscape (now Section of the Sahara Desert) is considered to are already covered with forests and braided rivers.

We are not referring to AA Duracells here. Dental batteries had been effective food stuff processing equipment employed by quite a few plant-having dinos.

The lizard from Niger was a relatively tiny sauropod, measuring all around nine meters (thirty ft) in size and weighing about four tons. It had an extended neck and tail, with a short, narrow snout that was tailored for browsing on small-lying vegetation.

Given that various rebbachisaurids inhabited latitudes that could are tropical to subtropical in the center Cretaceous, this pneumaticity could possibly have served the animals cope Along with the extremely significant temperatures. In keeping with Ibiricu and colleagues, this adaptation may be a motive why rebbachisaurids were the only real team of diplodocoids that survived in the Late Cretaceous.[21]

 Teeth at distinct growth levels, Museo di Storia Naturale di Venezia The slender teeth experienced somewhat curved tooth crowns, which were being oval in cross-part. The crowns have been distinct in owning distinguished ridges around the margins in their midline and sides. The teeth inside the reduce jaw may perhaps are 20–thirty% scaled-down than Those people in the higher jaw, but couple of are recognised, and they're of uncertain maturity. In addition to this, the teeth have been equivalent.[four] Under Each individual Energetic tooth there was a column of nine alternative teeth within the jaw.

The snout was also proportionately shorter, and also the tooth row was by no means prognathous, the snout suggestion not protruding relative to the remainder with the tooth collection.[1] Nigersaurus was distinct in that its frontal bone (which formed A lot on the cranium-roof) was elongate (Substantially narrower than very long), and had a marked cerebral fossa (a depression on the surface of this bone inside the head).[4] The maxillary tooth row was in its entirety transversely rotated, its typical rear 90° everted in the direction of the front. This was matched by The same rotation in the dentary with the reduce jaw. This transverse orientation on the upper and lessen tooth rows was exceptional into the dinosaur. On account of this configuration, no other tetrapod had all of its teeth Found as far to the entrance as Nigersaurus.[three][4]

Nigersaurus was in all probability a browser, and fed with its head close to the bottom. The area of its Mind that detected scent was small, While its Mind measurement was comparable to that of other dinosaurs. There was debate on no matter if its head was habitually held downwards, or horizontally like other sauropods.
