That vast muzzle with its Nigersaurus teeth was ideal for scooping up ferns, horsetails and other very low-lying crops. And Together with the bountiful teeth, the dinosaur would've had no difficulties shearing by way of this vegetation.
Head's Up! (Perhaps) Due to the fact Nigersaurus ate with its head down, experts have puzzled about its posture. Sereno and his co-authors once argued the herbivore aimed its facial area and neck downwards — whether or not it had been feeding or not — being a make a difference of pattern.
Judging because of the LSC orientation in Nigersaurus, Sereno and company hypothesized that the animal usually walked around with its snout pointed to the bottom in a sixty seven-degree angle. Picture a moping teen and you'll get The concept.

The dental structure of Nigersaurus supplies a must have insights in to the dietary and ecological adaptations of sauropods. Its exclusive dental arrangement and quick tooth substitution mechanism spotlight the numerous evolutionary methods that dinosaurs used to prosper of their environments.
Paleontologists Performing in Brazil have uncovered the fossil of an ornithuromorph chicken that lived throughout the Early...
Nigersaurus experienced over five hundred teeth organized in dental batteries (rows of teeth stacked upon other rows of teeth), which permitted it to efficiently graze on low-lying vegetation like ferns and horsetails. Worn teeth were being regularly replaced to take care of Niversaurus' powerful feeding.
Those jaws held some thing under no circumstances ahead of witnessed within a sauropod dinosaur: It had been among the list of to start with dinosaur skulls with tooth, or "dental," batteries.
Skeletal diagram demonstrating acknowledged things and size comparison Sereno as well as American palaeontologist Jeffrey A. Wilson presented the very first in-depth description on the skull and feeding adaptations in 2005.[1] In 2007, a more detailed description on the skeleton was revealed by Sereno advert colleagues, depending on a specimen learned 10 many years earlier. The fossils, in addition to a reconstructed skeleton mount in addition to a plastic design of The pinnacle and neck, had been subsequently offered for the Countrywide Geographic Modern society in Washington.
Nigersaurus was named after the West African place where its fossils have already been discovered: The Republic of Niger. Back when this animal roamed, 500 teeth dinosaur forests and braided rivers lined the landscape. (Nigersaurus would've needed to Be careful for Sarcosuchus, a tremendous relative of modern crocodiles.)

There were many light, aerated bones — usually connected to theropods, like Tyrannosaurus rex, plus the birds that progressed from them — And so the scientists assumed that was what they had been dealing with.
Having said that, as mentioned, Nigersaurus had a constant provide of latest teeth since they ended up changed when the leading tooth within a column wore out.
The fragile nature on the Nigersaurus’s slender teeth and sensitive cranium built excavation and preservation specifically challenging. Still, these difficulties have been fulfilled with innovative procedures in fossil Restoration and 3D reconstruction, permitting researchers to piece jointly the intricate details of its jaw as well as astonishing assortment of 500 teeth.
