As it was a prey animal, it had been critical for Nigersaurus to own movement hypersensitivity to detect any likely threats.
It lived in the riparian habitat, and its food plan almost certainly consisted of sentimental plants, for instance ferns, horsetails, and angiosperms. It is actually Probably the most common fossil vertebrates discovered in the region, and shared its habitat with other dinosaurian megaherbivores, as well as substantial theropods and crocodylomorphs.
Steady Tooth Substitute: Teeth had been replaced just about every 14 times, making sure a sharp, functional dental battery to cope with constant put on from grazing.
In generally vibrant manner, Sereno explained Nigersaurus to be a cross among Darth Vader and a vacuum cleaner and also called it a "Mesozoic cow" (not an inaccurate description, should you dismiss The truth that a complete-grown Nigersaurus measured 30 feet from head to tail and weighed up to five tons!)

lived in what is now Niger about a hundred and fifteen to a hundred and five million years in the past, throughout the Aptian and Albian ages with the mid-Cretaceous. It most likely lived in habitats dominated by inland floodplains (a riparian zone).
Which means that as just 500 teeth dinosaur one tooth wore down or broke off, another was willing to choose its place. This speedy tooth alternative cycle, occurring roughly every single fourteen times, ensured that Nigersaurus normally had practical teeth to approach its food items.

These well-known dinosaur reconstructions from your 1960s are no longer scientifically accurate. Can you see the glitches?
Its head is what truly stands out about Nigersaurus, while. The jaws, that have a flat front, are lined with about five hundred teeth, which Sereno states were being replaceable. These teeth have been all exactly the same in size, and he estimates which they almost certainly only lasted about a month or so ahead of they were worn down.
This permitted the dinosaur to get a constant supply of fresh new teeth, making it possible for it to continue to properly course of action plant substance at the same time as its teeth use down.
was named and explained in additional detail by Sereno and colleagues only in 1999, based upon continues to be of freshly uncovered folks. A similar write-up also named
The journey to uncover the secrets of the Nigersaurus commenced with the primary fossil fragments uncovered from the seventies inside the Elrhaz Formation of Niger, but it wasn’t until finally 1999 that additional comprehensive continues to be introduced this fascinating dinosaur to the spotlight. These discoveries presented paleontologists with both of those worries and opportunities.
Those jaws held a little something hardly ever in advance of witnessed within a sauropod dinosaur: It was one of the to start with dinosaur skulls with tooth, or "dental," batteries.
