Nigersaurus was named once the West African country the place its fossils are observed: The Republic of Niger. Back again when this animal roamed, forests and braided rivers included the landscape. (Nigersaurus would've needed to watch out for Sarcosuchus, a massive relative of contemporary crocodiles.)
They carved a block of rock that included each skulls, realizing whole well that it might weigh all around 600 lbs when encased in plaster.
Constant Tooth Substitution: Teeth were being changed every 14 days, ensuring a pointy, functional dental battery to cope with continual use from grazing.
Nigersaurus is a crucial discovery for paleontologists because it helps you to drop mild around the evolution and diversity of sauropods in the mid-Cretaceous period.

Nigersaurus is put in the class of sauropods in which each of the very long-necked and long-tailed dinosaurs are placed. Nigersaurus was possibly on the list of smallest sauropods since its neck was small. An Grownup Nigersaurus weighed about four tons and its size was similar to a modern Elephant.
Judging via the LSC orientation in Nigersaurus, Sereno and corporation hypothesized the animal typically walked around with its snout pointed to the ground in a 67-degree angle. Picture a moping teen and you'll get The reasoning.
Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) can be a genus of rebbachisaurid sauropod dinosaur that lived throughout the center Cretaceous period, about a hundred and fifteen to one zero five million decades in the past. It had been discovered from the Elrhaz Formation in a location called Gadoufaoua, in Niger.
A 2015 cladistic research by Wilsona and the French palaeontologist Ronan 500 teeth dinosaur Allain uncovered Rebbachisaurus alone to group Together with the nigersaurines, and the authors prompt that Nigersaurinae was for that reason a junior synonym of Rebbachisaurinae (due to the fact that title would have precedence).
And what a skeleton it was! The newfound fossils gave us our first look at the dino's difficult dental batteries and vacuum cleaner mouth. Sereno named the species Nigersaurus taqueti — being an homage to French paleontologist Philippe Taquet — in 1999.
Nigersaurus had issue in holding their head upward or horizontally. So feeding on leaves as well as other parts of prolonged Trees was not possible for them.
While other large animals examined (for instance rhinoceroses) had thick and variable bone cortices, the cortex of Nigersaurus was alternatively thin. These researchers proposed the microanatomy of sauropods wasn't affected by drastic selective stress brought on by bearing fat, but that features such as the columnar limbs (as noticed in elephants), pneumaticity, and fleshy foot pads and cartilage calm stress within the bones. In addition they recommended that sauropods may as a result are lighter in pounds than anticipated for his or her sizing, supporting the lowest physique mass estimates for these dinosaurs.[22]
This structure was among the main dinosaur skulls to get digitally reconstructed working with CT scans, presenting unparalleled insights into its feeding mechanics.
Nigersaurus was probably a browser, and fed with its head near the bottom. The region of its brain that detected scent was small, While its brain dimensions was similar to that of other dinosaurs. There have been debate on regardless of whether its head was habitually held downwards, or horizontally like other sauropods.
