Nigersaurus is placed from the classification of sauropods by which many of the extensive-necked and prolonged-tailed dinosaurs are put. Nigersaurus was probably one of several smallest sauropods due to the fact its neck was small. An Grownup Nigersaurus weighed all over four tons and its size was comparable to a modern Elephant.
Even so, a far more detailed paper on the whole Nigersaurus skeleton came in 2007. Presently, a lot of specimens uncovered by other paleontologists are less than evaluation and further more specifics will arise since the investigate will go on.
Beyond its paleontological importance, Nigersaurus has acquired attention on line as a consequence of its title. Some internet memes, especially the "Don't Google" craze, have highlighted the dinosaur as "the just one with 500 teeth.
Fossils of the dinosaur ended up initially explained in 1976, but it had been only named Nigersaurus taqueti in 1999, following more plus much more comprehensive continues to be had been uncovered and explained. The genus name usually means "Niger reptile", and the particular identify honours the palaeontologist Philippe Taquet, who learned the very first continues to be.

This sauropod (prolonged-necked dinosaur) has an unconventional cranium containing as a lot of as five hundred slender teeth. A major purpose of the expedition is to search out the rest of this abnormal dinosaur so we could explain it and reconstruct it for everyone to determine.
These teeth were specialized for competently cropping and grinding comfortable, reduced-lying vegetation. The dinosaur’s teeth ended up regularly replaced, with new ones rising each and every fourteen times to maintain features.
These teeth have been also replaceable (like sharks’ teeth), this means Nigersaurus frequently required clean teeth as more mature types ended up worn down or missing.
The swift substitute of its teeth, just about every fourteen times, indicates that the Nigersaurus confronted major evolutionary pressures to keep up a continuing source of purposeful teeth to manage with abrasive plant substance. This adaptation underlines the evolutionary essential to optimize feeding efficiency within an surroundings in which foodstuff resources different and Opposition was fierce.
The genus Nigersaurus was formally named in 1999 by American paleontologist Paul Sereno and his group, adhering to the discovery of extra full continues to be that permitted for a detailed description with the species.
After the iguanodontian Lurdusaurus, Nigersaurus was one of the most a lot of megaherbivore. Other herbivores from the similar formation include things like Ouranosaurus, Elrhazosaurus, and Nigersaurus an unnamed titanosaur. Collectively, these compose one of many number of associations of megaherbivores which has a stability of sauropods and enormous ornithopods.
On the basis of microtomography scans of skull factors of the holotype specimen, Sereno and colleagues developed a "prototype" Nigersaurus skull they may take a look at. Additionally they built an endocast from the Mind and scanned the semicircular canals of its internal ear, which they discovered to generally be oriented horizontally. Of their 2007 examine, they stated which the construction with the occiput behind the skull and cervical vertebrae would have restricted the upward and downward motion in the neck and also the rotation of your skull.
Horsetails (Equisetum) have a central, hollow stem with whorls of leaves or slim branches. They maintain their spores inside a cigar-shaped “cone” at the highest with the plant. Horsetails day again to ~370 million years ago. Throughout the start from the dinosaur era they grew being approximately thirty ft tall (10m.)
It experienced a brief neck for the sauropod, with 13 cervical vertebrae. Nearly all rebbachisaurids experienced somewhat small necks in addition to a duration of ten m (33 ft) or a lot less. The only real member with the relatives that arrived at the scale of much larger sauropods was
