Nigersaurus was named following the West African place where its fossils have been located: 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 huge relative of modern crocodiles.)
Nigersaurus is often a thirty-foot-long plant-having dinosaur that lived one hundred ten million many years in the past in what has become Niger’s Sahara Desert. Nigersaurus lived in the lush ecosystem along with the predatory dinosaur Suchomimus, the plant eaters ouranosaurus and lurdusaurus, and supercroc. Nigersaurus experienced a delicate cranium and a very large mouth lined with teeth Specifically tailored for browsing plants near the ground.

Bass fish are a few of the coolest creatures Youngsters can learn about. Not just are they interesting with their significant mouths and sharp
Skeletal diagram exhibiting acknowledged features and dimension comparison Sereno as well as the American palaeontologist Jeffrey A. Wilson supplied the first detailed description on the cranium and feeding adaptations in 2005.[1] In 2007, a more detailed description of the skeleton was printed by Sereno advert colleagues, based on a specimen learned ten yrs before. The fossils, along with a reconstructed skeleton mount plus a plastic product of The pinnacle and neck, had been subsequently presented with the Nationwide Geographic Modern society in Washington.
Dependant on this biomechanical Evaluation, the group concluded that The top and muzzle had been habitually oriented sixty seven° downwards and close to ground amount, as an adaptation for ground-level searching. This really is unlike the way other sauropods happen to be restored, with their heads held more horizontally.[3]
Nigersaurus is considered Nigersaurus to are actually a herbivore and could have fed on gentle crops making use of its long neck and a little head.
The most distinct characteristics of Nigersaurus was its rows of tiny, peg-like teeth, which had been organized in the straight line alongside the front of its jaws. These teeth were being consistently changed throughout the dinosaur’s life, allowing for it to feed consistently on hard vegetation.
The teeth’s unique condition and arrangement had been correctly suited for its feeding routines. The slender, chisel-like teeth could effectively snip off soft vegetation, and their fast alternative ensured the dinosaur could constantly feed with out expecting new teeth to grow.
This bizarre, extended-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with in excess of five hundred replaceable teeth. The first fossil skull of Nigersaurus
Nigersaurus had issues in holding their head upward or horizontally. So taking in leaves and other areas of extensive Trees was not possible for them.
Like other sauropods, Nigersaurus had an extended neck and tail. On the other hand, its neck was reasonably brief when compared to other members of its group, aligning with its reduced-grazing Life style. Its columnar legs supported its quadrupedal posture and helped bear its body weight effectively.
Fossils of the dinosaur had been to start with described in 1976, but it absolutely was only named Nigersaurus taqueti in 1999, right after further plus much more full continues to be were being located and described. The genus title usually means "Niger reptile", and the precise name honours the palaeontologist Philippe Taquet, who found out the initial continues to be.
Nigersaurus was in all probability a browser, and fed with its head near to the ground. The region of its Mind that detected smell was compact, Despite the fact that its brain sizing was akin to that of other dinosaurs. There's been debate on irrespective of whether its head was habitually held downwards, or horizontally like other sauropods.
