A 2009 study with the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was able to feed Together with the downturned head and neck posture proposed from the 2007 examine, but contested this was the habitual posture of your animal. The research observed that the "neutral" head and neck posture of modern animals doesn't necessarily correspond to their habitual head posture.
They consisted of vertically stacked columns of replaceable teeth. When the highest tooth wore out in any supplied column, the a single proper down below it might shift upwards and take the aged tooth's spot.

These teeth have been also replaceable (like sharks’ teeth), this means Nigersaurus continually essential refreshing teeth as older ones had been worn down or shed.
On the basis of microtomography scans of skull factors of the holotype specimen, Sereno and colleagues developed a "prototype" Nigersaurus skull they may take a look at. Additionally they produced an endocast on the Mind and scanned the semicircular canals of its inner ear, which they observed to become oriented horizontally. Within their 2007 review, they stated the framework of the occiput behind the skull and cervical vertebrae would've limited the upward and downward movement in the neck plus the rotation on the skull.
Sauropod dinosaurs, like Nigersaurus, walked on 4 legs, that has a extended “whiplash tail” and a long neck. But as compared to other sauropods, it absolutely was comparatively modest — sitting down somewhere involving an African and Indian elephant in measurement.
After the iguanodontian Lurdusaurus, Nigersaurus was one of the most numerous megaherbivore. Other herbivores with the exact same development contain Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. Alongside one another, these compose one of several handful of associations of megaherbivores with a stability of sauropods and enormous ornithopods.
While home to other significant herbivorous Nigersaurus dinosaurs, it was also inhabited by theropods (a gaggle of bipedal, three-toed carnivorous dinosaurs which include Tyrannosaurus Rex
Nevertheless, as outlined, Nigersaurus had a constant offer of new teeth since they had been replaced when the prime tooth inside of a column wore out.
Since many rebbachisaurids inhabited latitudes that might are already tropical to subtropical in the Middle Cretaceous, this pneumaticity could have assisted the animals cope Using the pretty large temperatures. According to Ibiricu and colleagues, this adaptation could be a rationale why rebbachisaurids had been the only real team of diplodocoids that survived into your Late Cretaceous.[21]
But that’s not all for Nigersaurus. Chris took us all to a flat location of purple-coloured sandstone exactly where he experienced located the higher jaw of a infant Nigersaurus—a person that might in good shape along with a silver greenback!

These teeth have been specialized for effectively cropping and grinding gentle, reduced-lying vegetation. The dinosaur’s teeth were frequently changed, with new types developing each 14 times to keep up functionality.
