That broad muzzle with its Nigersaurus teeth was ideal for scooping up ferns, horsetails and also other lower-lying plants. And While using the bountiful teeth, the dinosaur would've experienced no issues shearing by way of this vegetation.

All the tooth columns in Nigersaurus' dental batteries were being lined up, contrary to the teeth of other dinosaurs, with the really front of its mouth, positioned alongside the muzzle's gently curved periphery.

 Lifetime restoration Nigersaurus was distinct in that its dorsal (back again) vertebrae had paired pneumatic spaces at the base on the neural spines (the spines that projected upwards from the vertebrae). The presacral vertebrae (vertebrae in front of the sacrum) had been closely pneumatised to the point exactly where the column consisted of a series of hollow "shells", Every divided by a thin septum in the middle. It had small to no cancellous bone, producing the centra slim bone plates stuffed with air spaces. The vertebral arches have been so heavily pierced by extensions from the external air sacs that in their facet partitions little remained but 2 mm (0.

When Taquet initially explained the dinosaur’s stays within the 1970s, the formal classification and naming ended up conducted a long time afterwards by Sereno, emphasizing the collaborative mother nature of its review and discovery.

Teeth at diverse expansion stages, Museo di Storia Naturale di Venezia The slender teeth had a little bit curved tooth crowns, which have been oval in cross-segment. The crowns were being distinctive in having outstanding ridges over the margins of their midline and sides. The teeth while in the reduce jaw may possibly are 20–30% scaled-down than those in the upper jaw, but several are regarded, and they're of unsure maturity. In addition to this, the teeth were equivalent.[4] Beneath Just about every active tooth there was a column of nine substitution teeth within the jaw.

In 2019, Mannion and colleagues identified that because Nigersaurus was observed to generally be the sister taxon of all other nigersaurines in a few experiments, a Rebbachisaurinae clade may not automatically consist of Nigersaurus itself (in addition to the indisputable fact that the placement of Rebbachisaurus could improve in long term analyses), and supported the continued use in the identify Nigersaurinae over Rebbachisaurinae for all rebbachisaurids a lot more carefully relevant to Nigersaurus than to Limaysaurus.

After the iguanodontian Lurdusaurus, Nigersaurus was the most numerous megaherbivore. Other herbivores with the similar formation include things like Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. With each other, these compose on the list of couple of associations of megaherbivores that has a balance of sauropods and huge ornithopods.

Nigersaurus is known from many partial skeletons and isolated bones, that have supplied important details about its anatomy and actions.

A 2009 examine from the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was in a position to feed with the downturned head and neck posture proposed because of the 2007 analyze, but contested this was the habitual posture from the animal. The examine mentioned which the "neutral" head and neck posture of contemporary animals will not always correspond to what dinosaur has 500 teeth their habitual head posture.

Amongst the myriad of dinosaurs that when roamed our World, the Nigersaurus stands out, not for its sizing or ferocity, but for its remarkable dental composition.

A 2023 examine by the French palaeontologist Rémi Lefebvre and colleagues examined the microanatomical construction from the limb bones of Nigersaurus by way of CT-scans, the main this sort of review of the sauropod. Virtual sections of the limb bones sampled from individuals of different measurements were being explored to find out the choice of variation. Major-weight bearing animals usually have features connected with this affliction, affecting the inner construction on the limb bones, although the variation concerning these kinds of bones is improperly known.

This Nigersaurus was a hatchling, almost certainly a lot less than a person 12 months from hatching when it died and was fossilized.

‘ funny-hunting cranium, battery of teeth, and compact dimensions to get a sauropod have definitely gained it a spot during the annals of dinosaur oddities.

The Nigersaurus, with its staggering five hundred teeth, presents an interesting distinction to its dinosaur kin, Specifically other sauropods. Unlike its cousins with less, thicker teeth, the Nigersaurus’s slender, pencil-like teeth were being uniquely adapted for snipping smooth vegetation, a stark big difference from the strong teeth of sauropods like Brachiosaurus, which had been probable designed to take care of more durable vegetation.
