“It’s something that truly normally takes the cake for remarkable cranial adaptations With this team, the long-necked dinosaurs,” says Sereno, a professor of paleontology at the University of Chicago. “It’s only a majestic example of evolution.”
Nigersaurus is actually a thirty-foot-prolonged plant-consuming dinosaur that lived a hundred and ten million yrs ago in what has become Niger’s Sahara Desert. Nigersaurus lived within a lush setting together with the predatory dinosaur Suchomimus, the plant eaters ouranosaurus and lurdusaurus, and supercroc. Nigersaurus had a fragile skull and an especially vast mouth lined with teeth In particular tailored for browsing vegetation close to the ground.
Nigersaurus had above five hundred teeth arranged in dental batteries (rows of teeth stacked upon other rows of teeth), which permitted it to competently graze on reduced-lying vegetation like ferns and horsetails. Worn teeth had been frequently replaced to maintain Niversaurus' successful feeding.
The stays of Nigersaurus have been to begin with explained by Taquet in 1976 as belonging to the dicraeosaurid, but in 1999 Sereno and colleagues reclassified it for a rebbachisaurid diplodocoid.[4] These researchers speculated that since brief necks and small dimension was identified amid basal diplodocoids, it could reveal these had been ancestral options from the group.
The genus Nigersaurus was formally named in 1999 by American paleontologist Paul Sereno and his team, pursuing the discovery of extra full remains that allowed for an in depth description on the species.
In 2019, Mannion and colleagues pointed out that since Nigersaurus was discovered to get the sister taxon of all other nigersaurines in certain reports, a Rebbachisaurinae clade may well not essentially include Nigersaurus by itself (along with the indisputable fact that the placement of Rebbachisaurus could improve in long term analyses), and supported the ongoing use of the identify Nigersaurinae over Rebbachisaurinae for all rebbachisaurids far more intently connected to Nigersaurus than to Limaysaurus.
As we continue to check this interesting creature, we're reminded from the intricate and various paths that evolution might take.

Nigersaurus's feeding approach was not like a number of other dinosaurs. Its wide, flat jaw was tailored for grazing near to the ground, earning it the nickname "Mesozoic Cow."
The cranium of a Nigersaurus was made of slender bones and had numerous modest openings and pores. These attributes delivered them excellent flexibility in feeding on the bottom. The muzzle from the Nigersaurus was vast and prolonged which aided it in consuming small ground-primarily based vegetation.
This allowed the dinosaur to obtain a constant source of fresh new teeth, allowing for it to carry on to proficiently course of action plant substance whilst its teeth dress in down.
This Nigersaurus was a hatchling, in all probability less than 1 year from hatching when it died and was fossilized.
These teeth were specialised for successfully cropping and grinding tender, reduced-lying vegetation. The dinosaur’s teeth were constantly replaced, with new ones growing every 14 days to take care of performance.
In 2017, the Argentinian palaeontologist Lucio M. Ibiricu and colleagues examined the postcranial skeletal pneumaticity from what dinosaur has 500 teeth the skeletons of rebbachisaurids, and proposed that it was an adaptation for decreasing the density with the skeleton, and this could have lessened the muscle Vitality needed to shift the human body, along with the heat generated in the process.
