Following the iguanodontian Lurdusaurus, Nigersaurus was by far the most numerous megaherbivore. Other herbivores within the exact development involve Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. Collectively, these compose one of many handful of associations of megaherbivores with a stability of sauropods and enormous ornithopods.
The many tooth columns in Nigersaurus' dental batteries were lined up, contrary to the teeth of other dinosaurs, with the extremely entrance of its mouth, positioned along the muzzle's Carefully curved outer edge.
Nigersaurus was named and explained in more element by Sereno and colleagues only in 1999, determined by continues to be of recently uncovered persons. A similar posting also named Jobaria, An additional sauropod from Niger. The genus identify Nigersaurus ("Niger reptile") is actually a reference to the region where it absolutely was uncovered, and the specific identify taqueti honours Taquet, who was the very first to organise significant-scale palaeontological expeditions to Niger.
Nigersaurus was a genus of sauropod dinosaur that lived through the Late Cretaceous period, approximately 119-ninety nine million years back. Its fossils have been 1st found from the Republic of Niger, from which it derives its name.

” Our to start with 7 days in the sphere is breathtaking! Impressive discoveries appear to be waiting for us about every single dune. On our 1st working day, we located bones with the extensive-necked dinosaur Nigersaurus. Nigersaurus, you may perhaps try to remember, we named for bones gathered on the final expedition here three years back.
Inevitably, back while in the lab, Sereno had to request a second belief from colleagues who labored on fossil fish as well as other reptiles right before he figured it out.
[13] Due to the lateral orientation on the teeth, it in all probability would not have already been capable to chew.[one] Nigersaurus wore its tooth crowns down a lot quicker than other dinosaurian herbivores,[3] and its tooth substitution rate was the best of any recognised dinosaur. Each and every tooth was changed once each 14 times; the speed experienced Earlier been approximated decrease. In distinction to Nigersaurus, sauropods with lessen tooth substitution premiums and broader tooth crowns are assumed to have been Cover browsers.[twelve]
Nigersaurus's downward-facing mouth and extensive dental arrangement counsel it grazed on ground-amount crops rather then browsing substantial vegetation.
The skull of the Nigersaurus was crafted from skinny bones and experienced several modest openings and pores. These attributes offered them excellent adaptability in feeding on the ground. The muzzle with the Nigersaurus was large and prolonged which helped it in feeding on little floor-primarily based vegetation.
[13] Due to the lateral orientation on the teeth, it possibly wouldn't are already ready to chew.[one] Nigersaurus wore its tooth crowns down a lot quicker than other dinosaurian herbivores,[three] and its tooth alternative amount was the very best of any acknowledged dinosaur. Every single tooth was replaced as soon as each 14 times; the speed experienced Formerly been estimated reduce. In contrast to Nigersaurus, sauropods with lessen tooth substitution premiums and broader tooth crowns are considered to are already canopy browsers.[12]
Ingesting like which might be tough with your dental well being unless there is a syteady offer of substitute teeth. Nigersaurus should have worn out its tooth 500 teeth dinosaur crowns in a swift-hearth pace.
The dinosaur's vertebrae was stuffed with air pockets much like These of birds, And so the dinosaur was very likely quite gentle, too. Its brain was with regard to the measurement of the walnut, that is kind of common for sauropods, Sereno suggests.
Its short neck would have also been an adaptation to this ground-stage feeding habits, as it would not are already equipped to reach higher into trees like Various other sauropods.
