He uncovered quite a few fossils from Elrhaz formations in Niger. Between All those fossils, he uncovered fossils of a new dinosaur species that is known as Nigersaurus (“Niger Reptile”). He along with other paleontologists gathered quite a few bony portions of Nigersaurus separately and assembled a rough skeleton.

Reconstructed skeleton of Nigersaurus, showcasing the dinosaur's exceptional five hundred-tooth jaw construction and elongated overall body.

Nigersaurus was named and explained in additional detail by Sereno and colleagues only in 1999, depending on stays of newly located persons. The same article also named Jobaria, Yet another sauropod from Niger. The genus title Nigersaurus ("Niger reptile") is usually a reference to the nation where by it absolutely was found, and the particular title taqueti honours Taquet, who was the initial to organise massive-scale palaeontological expeditions to Niger.

Dinosaurs Have got a new relatives tree. Learn the way it's transformed and what the new tree reveals about dinosaurs' origins and evolution.

It experienced all-around five hundred slim teeth in its jaw that were replaced with new teeth in 2 weeks. Its upper jaw teeth had been more substantial than its decrease jaw teeth. Also, Its jaw was Significantly wider in comparison to the skull.

This sauropod (lengthy-necked dinosaur) has an abnormal cranium containing as quite a few as 500 slender teeth. A significant intention of this expedition is to seek out the rest of this abnormal dinosaur so we could describe it and reconstruct it for everybody to check out.

Sauropod dinosaurs, like Nigersaurus, walked on 4 legs, having a very long “whiplash tail” and a long neck. But when compared with other sauropods, it absolutely was comparatively compact — sitting somewhere concerning an African and Indian elephant in dimension.

Over-all, Nigersaurus was a unique and weird dinosaur as a result of its dental batteries and large muzzle, which authorized it to effectively system and what dinosaur has 500 teeth Obtain plant product. Its modest dimension and herbivorous food plan help it become an interesting contrast into the more substantial, carnivorous dinosaurs that are far more commonly acknowledged to the general public.

Issues got far more appealing in 1997. That is each time a member of Sereno's field staff discovered some Nigersaurus skull bones. Around the system of two expeditions, ample materials was uncovered to reconstruct about 80 percent of your beast's skeleton.

Nigersaurus also bears indications of lower-angle tooth-to-tooth wear on The within on the maxillary crowns, which implies that jaw motion was restricted to exact up-and-down motions. Worn teeth within the decreased jaw have not nevertheless been found out, but They may be envisioned to show opposing tooth-to-tooth wear. The ability to increase their heads very well above the ground isn't going to necessarily mean they browsed on things there, plus the shorter neck of Nigersaurus would have restricted the browsing selection when compared with other diplodocoids.[three]

 Everyday living restoration Nigersaurus was unique in that its dorsal (back again) vertebrae had paired pneumatic spaces at The bottom of your neural spines (the spines that projected upwards within the vertebrae). The presacral vertebrae (vertebrae before the sacrum) have been closely pneumatised to the point wherever the column consisted of a number of hollow "shells", Each individual divided by a thin septum in the middle. It experienced little to no cancellous bone, producing the centra slim bone plates crammed with air Areas. The vertebral arches had been so greatly pierced by extensions of your external air sacs that of their aspect walls minimal remained but two mm (0.

The Nigersaurus, with its five hundred teeth, showcases the marvels of evolution. Its specialised dental anatomy, tailored to its natural environment and diet plan, serves as being a testament for the adaptability and variety of prehistoric lifestyle.

The sauropod dinosaur Nigersaurus possible progressed its strangely-shaped head to raised mow prehistoric lawns.

The sauropod's jaw appears Nearly like a significant nail clipper, with massive rows of hundreds of teeth on its upper and lessen jaws. It Pretty much didn’t appear to fit into its skull when Sereno was looking to piece it together.
