Nigersaurus is placed in the classification of sauropods wherein all the extensive-necked and lengthy-tailed dinosaurs are positioned. Nigersaurus was likely one of the smallest sauropods because its neck was small. An Grownup Nigersaurus weighed all around 4 tons and its size was comparable to a contemporary Elephant.
Head's Up! (It's possible) Because Nigersaurus ate with its head down, specialists have questioned about its posture. Sereno and his co-authors at the time argued that the herbivore aimed its face and neck downwards — whether it was feeding or not — being a issue of pattern.
‘ skull was increased and located farther previously mentioned the muzzle compared to other sauropods. This means that its visual fields overlapped, resulting in a in close proximity to 360-degree area of view (very similar to contemporary cows).

It had all-around five hundred slender teeth in its jaw that were replaced with new teeth in two months. Its higher jaw teeth ended up much larger than its lessen jaw teeth. In addition, Its jaw was Significantly wider compared to skull.
In 2019, Mannion and colleagues pointed out that because Nigersaurus was uncovered being the sister taxon of all other nigersaurines in certain reports, a Rebbachisaurinae clade might not essentially contain Nigersaurus itself (along with the undeniable fact that the place of Rebbachisaurus could improve in long run analyses), and supported the continued use in the name Nigersaurinae around Rebbachisaurinae for all rebbachisaurids far more closely related to Nigersaurus than to Limaysaurus.
French paleontologists found the first fossils of Nigersaurus within the Nigerian Sahara throughout the nineteen fifties. Even so, considering the fact that most of the bones were both isolated or incomplete (due to their fragility), it absolutely was difficult to discover the species.
Even though other major animals examined (for instance rhinoceroses) experienced thick and variable bone cortices, the cortex of Nigersaurus was alternatively thin. These scientists suggested that the microanatomy of sauropods wasn't impacted by drastic selective tension attributable to bearing excess weight, but that options like the columnar limbs (as viewed in elephants), pneumaticity, and fleshy foot pads and cartilage comfortable pressure within the bones. In addition they advised that sauropods may perhaps consequently are already lighter in pounds than expected for their dimension, supporting the bottom body mass estimates for these dinosaurs.[22]
Factors acquired more interesting in 1997. Which is each time a member of Sereno's area team recognized some Nigersaurus skull bones. More than the course of two expeditions, plenty of content was found to reconstruct about eighty % of your beast's skeleton.
Nigersaurus was named once the West African country where by its fossils are already discovered: The Republic of Niger. Back again when this animal roamed, forests and braided rivers protected the landscape. (Nigersaurus would've needed to Be careful for Sarcosuchus, a big relative of 500 teeth dinosaur modern crocodiles.)
The 1st tracings of dinosaurs in Missouri were being located in the forties around the Chronister family's assets once they ended up digging a very well...
Among the myriad of dinosaurs that after roamed our World, the Nigersaurus stands out, not for its size or ferocity, but for its exceptional dental structure.
And what a skeleton it was! The newfound fossils gave us our initially consider the dino's complicated dental batteries and vacuum cleaner mouth. Sereno named the species Nigersaurus taqueti — being an homage to French paleontologist Philippe Taquet — in 1999.
The sauropod's jaw appears to be like Nearly like a significant nail clipper, with huge rows of many hundreds of teeth on its upper and lessen jaws. It Virtually didn’t manage to suit into its cranium when Sereno was attempting to piece it collectively.
