Nigersaurus was named once the West African region wherever its fossils happen to be discovered: The Republic of Niger. Back when this animal roamed, forests and braided rivers coated the landscape. (Nigersaurus would've had to Be careful for Sarcosuchus, a tremendous relative of recent crocodiles.)
Many of the tooth columns in Nigersaurus' dental batteries have been lined up, unlike the teeth of other dinosaurs, for the incredibly front of its mouth, positioned together the muzzle's gently curved periphery.
Continual Tooth Replacement: Teeth had been replaced each and every 14 times, making sure a pointy, useful dental battery to manage with constant put on from grazing.
The continues to be of Nigersaurus were initially described by Taquet in 1976 as belonging into a dicraeosaurid, but in 1999 Sereno and colleagues reclassified it for a rebbachisaurid diplodocoid.[four] These researchers speculated that considering that shorter necks and little measurement was identified amongst basal diplodocoids, it may show these had been ancestral attributes in the group.
Nigersaurus is believed to behave very like other herbivore sauropods. They had likely spent most of their time in cling-Pet dog positions and grazing reduced-lying vegetation.
In 2019, Mannion and colleagues identified that given that Nigersaurus was found to generally be the sister taxon of all other nigersaurines in certain research, a Rebbachisaurinae clade might not necessarily include things like Nigersaurus itself (plus the proven fact that the place of Rebbachisaurus could improve in potential analyses), and supported the ongoing use of the title Nigersaurinae around Rebbachisaurinae for all rebbachisaurids a lot more intently related to Nigersaurus than to Limaysaurus.
As we’ve noticed, Nigersaurus had a broad muzzle and various teeth correctly fitted to consuming very low-lying plants. This diet and lifestyle might have required the creature to possess a steady offer of substitution teeth, mainly because it would have worn out its tooth crowns rapidly. A study published during the journal PLOS One
Nigersaurus had a jaw structure in contrast to every other dinosaur. Its broad, squared-off muzzle housed about five hundred slender, pencil-like teeth. These teeth were not evenly dispersed but were arranged in columns and rows, with as quite a few as 9 substitute teeth at the rear of Each individual Lively tooth.
The Nigersaurus, with its remarkable dental array of 500 slender teeth in addition to a wide, squared-off muzzle, serves being a extraordinary window to the evolutionary paths that dinosaurs took to adapt to their environments. This specialized feeder, as opposed to lots of its sauropod kinfolk, progressed to snip and eat tender, abundant vegetation near the bottom, revealing a unique niche within the Cretaceous ecosystem.
This weird, lengthy-necked dinosaur is characterized by its unusually wide, straight-edged muzzle tipped with greater than five hundred replaceable teeth. The original fossil cranium of Nigersaurus

These teeth had been specialised for competently cropping and grinding tender, low-lying vegetation. The dinosaur’s teeth have been constantly changed, with new types developing every single fourteen times to take care of operation.
In 2017, the Argentinian palaeontologist Lucio M. Ibiricu and colleagues examined the postcranial skeletal pneumaticity from the skeletons of rebbachisaurids, and instructed that it had been an adaptation for reducing the density from the skeleton, and that this might have lessened the muscle mass Strength needed to move the human body, in addition to the what dinosaur has 500 teeth heat created in the method.
