Its head is what definitely stands out about Nigersaurus, nevertheless. The jaws, which have a flat front, are lined with about 500 teeth, which Sereno says had been replaceable. These teeth have been all the exact same in size, and he estimates that they almost certainly only lasted about a month or so ahead of they ended up worn down.
Its feeding fashion has been compared to that of recent grazing animals or even a vacuum cleaner, as it possible swept its head aspect-to-side even though consuming vegetation.
This sauropod (lengthy-necked dinosaur) has an uncommon skull that contains as lots of as five hundred slender teeth. A serious goal of the expedition is to seek out the remainder of this strange dinosaur so we can easily explain it and reconstruct it for everybody to check out.
It had around five hundred slender teeth in its jaw that were replaced with new teeth in 2 weeks. Its upper jaw teeth ended up bigger than its reduce jaw teeth. Moreover, Its jaw was A great deal broader than the cranium.
Teeth at unique expansion stages, Museo di Storia Naturale di Venezia The slender teeth had a little bit curved tooth crowns, which were being oval in cross-part. The crowns ended up unique in owning popular ridges about the margins of their midline and sides. The teeth within the decreased jaw could have been 20–30% smaller than those during the higher jaw, but several are acknowledged, and they are of uncertain maturity. Other than this, the teeth ended up equivalent.[4] Less than Just about every active tooth there was a column of nine substitute teeth throughout the jaw.
These teeth were being specialised for successfully cropping and grinding delicate, reduced-lying vegetation. The dinosaur’s teeth were being constantly replaced, with new types growing each individual 14 times to keep up functionality.
The dental constructions of Nigersaurus also propose that they ate soft crops in massive quantities to fulfill their nutritional necessities. They largely ate angiosperms, horsetails, and ferns as foods. Several paleontologists also believe that their five hundred carefully packed teeth arrangement also functioned like a comb. This comb-like teeth arrangement may have also helped them in filtering and having aquatic plants.

These teeth weren't evenly dispersed but had been arranged in columns and rows, with as a lot of as 9 alternative teeth powering Each individual active tooth.
“It’s something that genuinely can take the cake for remarkable cranial adaptations With this group, the long-necked dinosaurs,” states Sereno, a professor of paleontology in the University of Chicago. “It’s just a majestic illustration of evolution.”
