Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is really a genus of rebbachisaurid sauropod dinosaur that lived all through the middle Cretaceous interval, about one hundred fifteen to 105 million decades in the past. It had been found during the Elrhaz Development in an area referred to as Gadoufaoua, in Niger.

First discoveries of Nigersaurus fossils date back again into the nineteen sixties, however it was not until the seventies that extra finish remains have been uncovered. These continues to be have been formally analyzed and explained by paleontologist Paul Sereno and his group in 1999.

Whilst Taquet originally explained the dinosaur’s stays from the seventies, the formal classification and naming have been carried out a long time later on what dinosaur has 500 teeth by Sereno, emphasizing the collaborative character of its research and discovery.

Hans continues to be working with a crew of Allison and Dave to excavate a different website. As we dug around the cranium, we uncovered A further juvenile skull of exactly the same species lying suitable beside the massive 1.

The confined comprehension of the genus was the result of inadequate preservation of its stays, which arises from your sensitive and very pneumatic building (filled with air spaces connected to air sacs) of the cranium and skeleton, subsequently creating disarticulation in the fossils. Several of the skull fossils have been so skinny that a powerful light beam was visible through them. For that reason, no intact skulls or articulated skeletons are already located, and these specimens depict by far the most finish regarded rebbachisaurid remains.[3][one]

“It’s a thing that definitely takes the cake for wonderful cranial adaptations In this particular team, the extensive-necked dinosaurs,” suggests Sereno, a professor of paleontology within the College of Chicago. “It’s merely a majestic illustration of evolution.”

Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is usually a genus of rebbachisaurid sauropod dinosaur that lived in the course of the center Cretaceous interval, about 115 to a hundred and five million yrs ago. It had been found out within the Elrhaz Development in a region called Gadoufaoua, in Niger.

Nigersaurus was named and explained in more element by Sereno and colleagues only in 1999, dependant on remains of freshly identified individuals. The identical short article also named Jobaria, another sauropod from Niger. The genus identify Nigersaurus ("Niger reptile") is usually a reference towards the region where by it was learned, and the precise name taqueti honours Taquet, who was the initial to organise massive-scale palaeontological expeditions to Niger.

The speedy tooth replacement indicates that it primarily fed on smooth, abrasive crops, which would dress in down its teeth immediately.
