The region that Nigersaurus roamed all All those numerous yrs back could are actually idyllic in certain techniques, but it surely wasn't without having its quite a few significant dangers.
Even though walking across an incredibly flat area, Gabe made a extraordinary find—the bones of a different meat-feeding on dinosaur lay partially exposed at her toes. She brushed away the sand through the upper jaw.

Nigersaurus also bears indications of reduced-angle tooth-to-tooth put on on the inside in the maxillary crowns, which indicates that jaw motion was restricted to exact up-and-down motions. Worn teeth from your decreased jaw haven't nevertheless been discovered, but They are really expected to indicate opposing tooth-to-tooth put on. The chance to raise their heads very well above the ground isn't going to essentially suggest they browsed on items there, as well as the shorter neck of Nigersaurus would've limited the searching variety in comparison with other diplodocoids.[3]
What dinosaur has 500 teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert 110 million decades back. These sauropod dinosaurs gathered food items having a large, broad mouth; the snout was wider compared to the back again on the creature's head on the first fossil cranium.
If accurate, it would starkly distinction with most sauropod reconstructions, exhibiting the animal holding its head horizontally.
The restricted understanding of the genus was the results of very poor preservation of its stays, which occurs within the delicate and extremely pneumatic development (crammed with air spaces connected to air sacs) on the cranium and skeleton, subsequently creating disarticulation on the fossils. Many of the cranium fossils have been so slender that a robust gentle beam was obvious through them. Consequently, no intact skulls or articulated skeletons are found, and these specimens symbolize one of the most complete recognised rebbachisaurid remains.[three][1]
This immediate tooth substitution, with new teeth increasing every fourteen days, ensured it managed sharp edges for grazing on soft vegetation. The special dental arrangement made it highly productive at processing very low-lying crops, contributing to its standing to be a specialised herbivore.
The Nigersaurus, with its incredible dental variety of five hundred slender teeth along with a wide, squared-off muzzle, serves being a impressive window in the evolutionary paths that dinosaurs took to adapt to their environments. This specialized feeder, not like a lot of its sauropod kinfolk, progressed to snip and consume comfortable, ample vegetation near the ground, revealing a unique market inside the Cretaceous ecosystem.
For instance, its fossils suggest that it had a large, deep ribcage which could have permitted it to absorb massive quantities of air, facilitating its respiration and providing Nigersaurus the oxygen it necessary to sustain its enormous entire body.
We have been a bunch of biologists and paleontologists, generating content articles and well known science publications that existing the globe of animals, plants and introduce the nuances of paleontology in an obtainable way for viewers.
Paleontologists think that their habits is usually as opposed with right now’s cows. Nigersaurus ended up social and remained herds as being a safety tactic. Because of insufficient fossil proof, the copy tactic of Nigersaurus is not really identified.
Dinosaur-hunters are accustomed to acquiring dental batteries in beaked herbivores such as horned Triceratops and shovel-billed Edmontosaurus. But they're uncommon One of the sauropods.
What's more, the same as grazing cows nowadays, these creatures ended up considerable all through their heyday. Following the Original discovery, Sereno uncovered another Nigersaurus specimen during an expedition in 2000.
