A 2009 examine because of the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was capable of feed Along with the downturned head and neck posture proposed through the 2007 analyze, but contested that this was the habitual posture of your animal. The study observed which the "neutral" head and neck posture of modern animals won't essentially correspond to their habitual head posture.
They carved a block of rock that integrated both skulls, knowing total perfectly that it could weigh all around 600 lbs when encased in plaster.
Teeth at distinctive growth levels, Museo di Storia Naturale di Venezia The slender teeth experienced a little bit curved tooth crowns, which have been oval in cross-portion. The crowns had been distinctive in getting outstanding ridges over the margins of their midline and sides. The teeth from the lower jaw could are already twenty–thirty% more compact than Those people in the upper jaw, but handful of are recognised, and they are of uncertain maturity. Other than this, the teeth were being similar.[four] Under Each and every Energetic tooth there was a column of 9 substitute teeth in the jaw.
Since quite a few rebbachisaurids inhabited latitudes that would have been tropical to subtropical in the center Cretaceous, this pneumaticity can have served the animals cope with the very high temperatures. According to Ibiricu and colleagues, this adaptation could be a motive why rebbachisaurids were being the sole group of diplodocoids that survived into your Late Cretaceous.[21]
When other significant animals examined (which include rhinoceroses) had thick and variable bone cortices, the cortex of Nigersaurus was somewhat thin. These researchers proposed that the microanatomy of sauropods wasn't afflicted by drastic selective stress due to bearing pounds, but that functions including the columnar limbs (as viewed in elephants), pneumaticity, and fleshy foot pads and cartilage peaceful tension about the bones. Additionally they proposed that sauropods may possibly as a result have already been lighter in excess weight than expected for their sizing, supporting the bottom body mass estimates for these dinosaurs.[22]
Like other sauropods, Nigersaurus had a lengthy neck and tail. On the other hand, its neck was rather small as compared to other customers of its group, aligning with its very low-grazing Life-style. Its columnar legs supported its quadrupedal posture and aided bear its bodyweight successfully.
As we’ve found, Nigersaurus had a wide muzzle and numerous teeth perfectly suited for consuming reduced-lying plants. This diet and Way of life might have essential the creature to have a steady supply of substitution teeth, as it would have worn out its tooth crowns fast.

Hans has actually been working with a crew of Allison and Dave to excavate a whole new site. As we dug throughout the cranium, we uncovered another juvenile skull of the exact same species lying correct close to the massive 1.
The limited idea of the genus was the results of poor preservation of its stays, which occurs through the delicate and extremely pneumatic building (full of air spaces connected to air sacs) on the cranium and skeleton, subsequently leading to disarticulation in the fossils. A lot of the skull fossils have been so skinny that a powerful light beam was visible as a result of them. Consequently, no intact skulls or articulated skeletons have already been observed, and these specimens represent quite possibly the most full known rebbachisaurid remains.[3][1]
The Nigersaurus, with its incredible dental variety of 500 slender teeth in addition to a wide, squared-off muzzle, serves being a outstanding window into your evolutionary paths that dinosaurs took to adapt to their environments. This specialised feeder, in contrast to lots of its sauropod family, progressed to snip and eat gentle, ample vegetation near to the bottom, revealing a singular area of interest inside the Cretaceous ecosystem.
Its special dental framework suggests that it may have had a different feeding system as compared to other sauropods, and its presence in Africa indicates that these kinds of dinosaurs were being a lot more widespread than Beforehand imagined.
The limited understanding of the genus was the result of lousy preservation of its remains, which arises from the sensitive and remarkably pneumatic development (stuffed with air Areas linked to air sacs) in the skull and skeleton, consequently triggering disarticulation in the fossils. Several of the cranium fossils have been so slim that a robust mild beam was noticeable via them. As a result, no intact skulls or articulated skeletons have already been identified, and these specimens signify essentially the most total identified rebbachisaurid stays.[3][one]
Only by bringing together vegetation from across the world and many different modern environments can a dinosaur-age scene be recreated. Many of the plants, like ginkgos, glimpse practically similar to their extinct ancestors; some, such as the conifer Araucaria, were being the dominant trees on the forests 110 million yrs ago.
‘ funny-hunting skull, battery of teeth, and little Nigersaurus dimensions for a sauropod have surely won it an area within the annals of dinosaur oddities.
