That broad muzzle with its Nigersaurus teeth was perfect for scooping up ferns, horsetails together with other small-lying vegetation. And with the bountiful teeth, the dinosaur would've had no hassle shearing through this vegetation.
As we keep on to study this intriguing creature, we're reminded on the intricate and varied paths that evolution usually takes.
Nigersaurus was named and described in more detail by Sereno and colleagues only in 1999, determined by continues to be of newly identified folks. A similar article also named Jobaria, Yet another sauropod from Niger. The genus identify Nigersaurus ("Niger reptile") is often a reference to the nation the place it absolutely was learned, and the precise name taqueti honours Taquet, who was the 1st to organise large-scale palaeontological expeditions to Niger.
While it experienced significant nostrils and a fleshy snout, Sereno and colleagues discovered that Nigersaurus had an underdeveloped olfactory region of its brain and therefore did not have an advanced feeling of smell. Its brain-to-overall body-mass ratio was ordinary to get a reptile, and smaller sized than Individuals of ornithischians and non-coelurosaurian theropods. The cerebrum comprised about 30% in the brain volume, as in many other dinosaurs.[3] The American palaeoartist Mark Hallett and paleontologist Mathew J.

This strange, prolonged-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with much more than five hundred replaceable teeth. The original fossil cranium of Nigersaurus has become the very first dinosaur skulls to become digitally reconstructed from CT scans.
French paleontologists uncovered the 1st fossils of Nigersaurus while in the Nigerian Sahara in the course of the 1950s. Even so, considering that a lot of the bones were both isolated or incomplete (due to their fragility), it absolutely was unachievable to recognize the species.
Hans has long been working with a crew of Allison and Dave to excavate a brand new web site. As we dug round the skull, we uncovered One more juvenile skull of the exact same species lying proper next to the large just one.
A 2015 cladistic research by Wilsona as well as French palaeontologist Ronan Allain discovered Rebbachisaurus by itself to group While using the nigersaurines, as well as authors advised that Nigersaurinae was consequently a junior synonym of Rebbachisaurinae (because that identify would have precedence).
The authors therefore cautioned versus applying semicircular canals as proxy to infer the exact orientation of skulls. They identified that diet correlated strongly with semicircular canal orientation, but not with head posture, when head posture and semicircular canal orientation have been strongly correlated with phylogeny.[25]
In 2020, the French palaeontologist Julien Benoit and colleagues examined lateral semicircular canal correlation to move posture on modern mammals, and located that when there was substantial correlation concerning the reconstructed and precise head postures, the aircraft in the semicircular canal wasn't held horizontally during the resting pose as inferred.
Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is often a genus of rebbachisaurid sauropod dinosaur that lived during the middle Cretaceous interval, about 115 to one zero what dinosaur has 500 teeth five million yrs in the past. It absolutely was identified from the Elrhaz Development in an area referred to as Gadoufaoua, in Niger.
[thirteen] As a result of lateral orientation in the teeth, it probably wouldn't have already been in a position to chew.[one] Nigersaurus wore its tooth crowns down more rapidly than other dinosaurian herbivores,[3] and its tooth alternative rate was the best of any identified dinosaur. Every tooth was changed when every fourteen days; the speed had Beforehand been approximated decreased. In contrast to Nigersaurus, sauropods with lessen tooth alternative premiums and broader tooth crowns are considered to happen to be Cover browsers.[12]
eight ft) in size and weighing about 2 tons. Inspite of its small size compared to other sauropods, it received awareness as a result of its distinctive anatomy, which includes a broad muzzle resembling a vacuum cleaner and dental batteries consisting of many small, needle-formed teeth arranged in columns.
