Once the iguanodontian Lurdusaurus, Nigersaurus was essentially the most several megaherbivore. Other herbivores with the exact same formation include Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. Together, these compose among the list of number of associations of megaherbivores with a balance of sauropods and huge ornithopods.
It further argued that the orientation on the semicircular canals may differ substantially within just fashionable species, and it is thus not trusted for pinpointing head posture.[23] This was supported by the Spanish palaeontologist Jesús Marugán-Lobón and colleagues in a very 2013 research that prompt the methods used by Sereno's group have been imprecise, Which Nigersaurus habitually held its head like other sauropods.[24]
Beyond its paleontological importance, Nigersaurus has gained attention on the net resulting from its title. Some World-wide-web memes, significantly the "Do not Google" craze, have highlighted the dinosaur as "the a single with five hundred teeth.
But that’s not all for Nigersaurus. Chris took us all to your flat location of purple-colored sandstone wherever he experienced located the higher jaw of a baby Nigersaurus—just one that might match in addition to a silver greenback!
Teeth at distinct growth stages, Museo di Storia Naturale di Venezia The slender teeth experienced somewhat curved tooth crowns, which had been oval in cross-portion. The crowns have been unique in getting notable ridges to the margins of their midline and sides. The teeth in the decrease jaw may are already twenty–30% lesser than Individuals during the higher jaw, but few are recognised, and they are of uncertain maturity. In addition to this, the teeth were equivalent.[4] Underneath Each individual active tooth there was a column of nine replacement teeth in the jaw.
The review of dinosaurs like Nigersaurus aids us to raised recognize the heritage of our planet plus the crucial purpose that these historical creatures played in shaping the earth as we realize it currently.
Because of this as a single tooth wore down or broke off, An additional was ready to acquire its place. This swift tooth replacement cycle, happening roughly every fourteen days, ensured that Nigersaurus generally had purposeful teeth to procedure its foods.

Daily life restoration Nigersaurus was distinct in that its dorsal (again) vertebrae experienced paired pneumatic Areas at The bottom of the neural spines (the spines that projected upwards through the vertebrae). The presacral vertebrae (vertebrae in front of the sacrum) were seriously pneumatised to the point wherever the column consisted of a number of hollow "shells", Every divided by a skinny septum in the middle. It had tiny to no cancellous bone, creating the centra slender bone plates filled with air spaces. The vertebral arches have been so seriously pierced by extensions of the exterior air sacs that in their side partitions very little remained but two mm (0.
Fossils of this dinosaur had been very first described in 1976, but it was only named Nigersaurus taqueti in 1999, following even more and a lot more finish continues to be ended up located and explained. The genus title indicates "Niger reptile", and the particular title honours the palaeontologist Philippe Taquet, who uncovered the primary remains.
Improved however, People tooth columns were packed appropriate alongside what dinosaur has 500 teeth each other—like canned sardines. So a dinosaur armed with dental batteries could easily dwelling a number of hundred teeth (old and new) within its mouth.
It experienced a short neck for the sauropod, with thirteen cervical vertebrae. Nearly all rebbachisaurids experienced fairly small necks along with a size of ten m (33 ft) or fewer. The only member of your family that achieved the size of more substantial sauropods was
Skeletal diagram displaying regarded components and dimensions comparison Sereno and also the American palaeontologist Jeffrey A. Wilson delivered the very first in depth description in the cranium and feeding adaptations in 2005.[1] In 2007, a far more in-depth description of your skeleton was printed by Sereno advert colleagues, according to a specimen found 10 yrs previously. The fossils, in addition to a reconstructed skeleton mount and a plastic design of The pinnacle and neck, have been subsequently offered within the Nationwide Geographic Modern society in Washington.
In 2017, the Argentinian palaeontologist Lucio M. Ibiricu and colleagues examined the postcranial skeletal pneumaticity inside the skeletons of rebbachisaurids, and proposed that it absolutely was an adaptation for decreasing the density of the skeleton, and this might have diminished the muscle mass Electrical power required to move the human body, together with the warmth produced in the process.
