The Air Apparent Nigersaurus stayed under the radar for fairly a while. The initial acknowledged fossils belonging to this animal were being recovered in the course of the nineteen fifties by French paleontologists from the Nigerian Sahara. Sadly, The majority of these bones ended up isolated or fragmentary.
Considering the fact that numerous rebbachisaurids inhabited latitudes that could have already been tropical to subtropical in the Middle Cretaceous, this pneumaticity could possibly have assisted the animals cope Along with the extremely substantial temperatures. In keeping with Ibiricu and colleagues, this adaptation could be a reason why rebbachisaurids had been the one team of diplodocoids that survived into your Late Cretaceous.[21]
Nigersaurus experienced over 500 teeth arranged in dental batteries (rows of teeth stacked on other rows of teeth), which allowed it to proficiently graze on small-lying vegetation like ferns and horsetails. Worn teeth have been regularly changed to take care of Niversaurus' successful feeding.
The authors therefore cautioned versus working with semicircular canals as proxy to infer the exact orientation of skulls. They identified that diet correlated strongly with semicircular canal orientation, although not with head posture, when head posture and semicircular canal orientation have been strongly correlated with phylogeny.[25]
It had been found inside the rich fossil vertebrate fauna with the Elrhaz Development in a place referred to as Gadoufaoua, during the Republic of Niger. Fossils of this dinosaur have been initially explained in 1976, but it absolutely was only named in 1999 soon after additional complete remains were being located and explained.

Nigersaurus was named after Nigersaurus the West African region where its fossils were being found: the Republic of Niger. For the duration of this creature’s time, the landscape (now A part of the Sahara Desert) is believed to are already covered with forests and braided rivers.
A completely new genus and species of toothless noasaurid ceratosaur has actually been discovered from an extremely comprehensive skeleton present in...
The Nigersaurus, with its amazing dental array of five hundred slender teeth and also a broad, squared-off muzzle, serves for a exceptional window to the evolutionary paths that dinosaurs took to adapt for their environments. This specialized feeder, in contrast to lots of its sauropod kinfolk, progressed to snip and take in gentle, plentiful vegetation close to the ground, revealing a unique market in the Cretaceous ecosystem.

Teeth at distinctive expansion stages, Museo di Storia Naturale di Venezia The slender teeth experienced somewhat curved tooth crowns, which were being oval in cross-part. The crowns have been distinctive in obtaining notable ridges over the margins of their midline and sides. The teeth during the reduce jaw may are twenty–thirty% smaller sized than Those people inside the higher jaw, but couple of are recognised, and they are of unsure maturity. Aside from this, the teeth were being similar.[four] Below Just about every active tooth there was a column of 9 replacement teeth in the jaw.
Regardless of the memes, Nigersaurus remains an extraordinary example of evolution and adaptation, deserving recognition for its exceptional features as an alternative to Online controversy.
Items bought more appealing in 1997. That's whenever a member of Sereno's subject workforce noticed some Nigersaurus skull bones. Around the program of two expeditions, ample substance was discovered to reconstruct about eighty p.c of the beast's skeleton.
Its quick neck would've also been an adaptation to this ground-degree feeding conduct, as it wouldn't have already been capable to succeed in high into trees like Several other sauropods.
