A 2009 review from the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was capable of feed Using the downturned head and neck posture proposed because of the 2007 examine, but contested that this was the habitual posture on the animal. The research observed that the "neutral" head and neck posture of recent animals isn't going to necessarily correspond for their habitual head posture.
Since quite a few rebbachisaurids inhabited latitudes that may happen to be tropical to subtropical in the Middle Cretaceous, this pneumaticity may have aided the animals cope Along with the pretty substantial temperatures. According to Ibiricu and colleagues, this adaptation may be a explanation why rebbachisaurids were the only team of diplodocoids that survived in to the Late Cretaceous.[21]
A 2023 analyze through the French palaeontologist Rémi Lefebvre and colleagues examined the microanatomical framework from the limb bones of Nigersaurus by way of CT-scans, the main this sort of review of a sauropod. Virtual sections on the limb bones sampled from individuals of various dimensions had been explored to determine the choice of variation. Heavy-fat bearing animals often have attributes connected to this condition, affecting the internal structure from the limb bones, but the variation amongst these bones is badly recognized.
Although Taquet initially explained the dinosaur’s remains inside the 1970s, the formal classification and naming were executed decades afterwards by Sereno, emphasizing the collaborative character of its analyze and discovery.
Nigersaurus desired to live in spots possessing water Lakes or streams close by; the region is also known as the riparian zone. Due to abundant h2o, a riparian zone has many minimal-lying vegetation. Riparian zones deliver Nigersaurus with quite a few varieties of vegetation.
These teeth and the shape in the sauropod's skull possible evolved to help it munch on vegetation small to the ground. Grass wasn’t around yet in the course of its time, but Nigersaurus in all probability expended Substantially of its time grazing on something like it, wearing down its teeth very quickly.
Which means as just one tooth wore down or broke off, another was willing to choose its location. This swift tooth alternative cycle, happening about every 14 days, ensured that Nigersaurus constantly experienced purposeful teeth to process its foodstuff.
Nigersaurus are popular dinosaurs for acquiring five hundred slender teeth of their jaw. These dinosaurs are actually regarded a short while ago in the yr 2000 and ended up named in the honour of place “Niger”. The word Nigersaurus has two components; Niger (nation title), and Saurus (reptile).
In 2019, Mannion and colleagues pointed out that due to the fact Nigersaurus was found to generally be the sister taxon of all other nigersaurines in certain reports, a Rebbachisaurinae clade may well not essentially incorporate Nigersaurus by itself (plus the undeniable fact that the placement of Rebbachisaurus could modify in upcoming analyses), and supported the continued use from the title Nigersaurinae over Rebbachisaurinae for all rebbachisaurids much more intently linked to Nigersaurus than to Limaysaurus.

[13] Because of the lateral orientation in the teeth, it probably would not happen to be able to chew.[1] Nigersaurus wore its tooth crowns down more rapidly than other dinosaurian herbivores,[3] and its tooth substitute price was the very best of any recognized dinosaur. Each individual tooth was changed as soon as every 14 days; the speed had Earlier been approximated reduce. In contrast to Nigersaurus, sauropods with decrease tooth substitute charges and broader tooth crowns are imagined to are actually Cover browsers.[12]
Nigersaurus lived in Nigersaurus what is currently the Sahara Desert during the mid-Cretaceous interval, approximately a hundred and fifteen to one hundred and five million yrs back, within a lush, riverine habitat with ample flowers.
The dinosaur's vertebrae was filled with air pockets just like Individuals of birds, Hence the dinosaur was very likely fairly gentle, likewise. Its Mind was about the dimensions of a walnut, which can be kind of ordinary for sauropods, Sereno says.
This intriguing variation showcases the diverse methods dinosaurs formulated to prosper within their environments. The Nigersaurus’s rapid tooth substitute, happening each individual fourteen days, can also be outstanding, location it aside from other sauropods that experienced slower tooth turnover.
