A 2009 research with the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was ready to feed With all the downturned head and neck posture proposed from the 2007 examine, but contested that this was the habitual posture from the animal. The research pointed out that the "neutral" head and neck posture of recent animals will not necessarily correspond to their habitual head posture.
Head's Up! (Perhaps) Since Nigersaurus ate with its head down, industry experts have puzzled about its posture. Sereno and his co-authors at the time argued that the herbivore aimed its encounter and neck downwards — regardless of whether it absolutely was feeding or not — as being a make any difference of habit.
Feeding on like that may be rough with your dental well being Except if you have a syteady provide of substitute teeth. Nigersaurus have to have worn out its tooth crowns in a quick-fireplace pace.
Its cranium was pretty specialised for feeding. It had 4 significant side fenestrae, openings in the cranium and thin bones. It had a large muzzle crammed with in excess of five hundred teeth, which had been changed about each individual 14 times. The jaws might have experienced a keratinous sheath, some thing similar to a vast beak. Nigersaurus is the only real recognized tetrapod animal to own experienced jaws broader compared to the skull and teeth that prolonged laterally across the entrance.
If correct, it would starkly distinction with most sauropod reconstructions, showing the animal holding its head horizontally.

Just like other Sauropods, Nigersaurus have been herbivores. They had grazed close to the bottom and ate lower-lying vegetation. They had a wide muzzle which aided them in cropping far more vegetative product in just one bite. You might Feel they almost certainly ate grass, even so the grass hadn’t evolved in the course of that time.
Hans continues to be working with a crew of Allison and Dave to excavate a different website. As we dug around the skull, we uncovered A different juvenile skull of the exact same species lying correct beside the massive a single.
Our very first week in the sphere is spectacular! Extraordinary discoveries appear to be awaiting us all over each and every dune. On our first day, we located bones of the very long-necked dinosaur Nigersaurus. Nigersaurus, you could remember, we named for bones collected on the last expedition right here three yrs Nigersaurus ago.
Excellent detail it had a continuing provide of fresh new replacement teeth. As outlined by a 2013 study released from the journal PLOS Just one, Nigersaurus possible changed each "new" tooth following just 14 times.
Wedel and said in 2016 that though sauropods normally could use their prolonged necks to detect predators from afar, This is able to not apply for the limited-necked Nigersaurus. They identified which the eyes of Nigersaurus were placed even more to the top from the skull than in many other sauropods, earlier mentioned the muzzle, which might give it overlapping fields of watch. Its Visible field would've been at or near to 360 degrees, and hypersensitivity of motion might have been essential to a vulnerable prey-animal.[20]
Amongst the myriad of dinosaurs that once roamed our Earth, the Nigersaurus stands out, not for its sizing or ferocity, but for its outstanding dental framework.
Even the skies have been occupied – extensive-winged flying pterosaurs swooped overhead, often diving down to grab a tasty fish out with the river.
The fragile character on the Nigersaurus’s slender teeth and fragile cranium produced excavation and preservation notably complicated. However, these challenges have been fulfilled with ground breaking techniques in fossil recovery and 3D reconstruction, letting experts to piece together the intricate particulars of its jaw along with the astonishing assortment of five hundred teeth.
