The Air Obvious Nigersaurus stayed underneath the radar for fairly a while. The very first regarded fossils belonging to this animal ended up recovered over the fifties by French paleontologists from the Nigerian Sahara. Sad to say, A large number of bones ended up isolated or fragmentary.
Because quite a few rebbachisaurids inhabited latitudes that would are tropical to subtropical in the center Cretaceous, this pneumaticity could possibly have helped the animals cope Together with the extremely large temperatures. In keeping with Ibiricu and colleagues, this adaptation could be a rationale why rebbachisaurids have been the one group of diplodocoids that survived in the Late Cretaceous.[21]
Named after the nation of Niger, where by its fossils were initial uncovered. The identify was picked out to replicate its origins, having said that, the similarity in pronunciation into a racial slur has raised considerations about cultural sensitivity and suitable terminology.
But that’s not all for Nigersaurus. Chris took us all to some flat space of purple-colored sandstone the place he experienced located the upper jaw of the child Nigersaurus—1 that will in good shape on top of a silver dollar!
On The premise of microtomography scans of cranium elements on the holotype specimen, Sereno and colleagues made a "prototype" Nigersaurus skull they may examine. In addition they built an endocast from the brain and scanned the semicircular canals of its inner ear, which they found to be oriented horizontally. In their 2007 study, they mentioned which the framework with the occiput in the back of the skull and cervical vertebrae would have minimal the upward and downward motion on the neck plus the rotation with the skull.
Sauropod dinosaurs, like Nigersaurus, walked on four legs, by using a very long “whiplash tail” and a long neck. But compared to other sauropods, it was rather small — sitting down someplace concerning an African and Indian elephant in sizing.
Judging by the LSC orientation in Nigersaurus, Sereno and company hypothesized that the animal typically walked close to with its snout pointed to the ground in a 67-diploma angle. Image a moping teen and you'll get The thought.
We are not talking about AA what dinosaur has 500 teeth Duracells right here. Dental batteries had been economical food stuff processing instruments employed by quite a few plant-feeding on dinos.
In 2019, Mannion and colleagues identified that given that Nigersaurus was found to get the sister taxon of all other nigersaurines in some reports, a Rebbachisaurinae clade may not always include Nigersaurus itself (in addition to the fact that the place of Rebbachisaurus could change in long term analyses), and supported the continued use of the title Nigersaurinae about Rebbachisaurinae for all rebbachisaurids much more carefully associated with Nigersaurus than to Limaysaurus.

It more argued that the orientation in the semicircular canals differs appreciably within just present day species, and is particularly consequently not responsible for figuring out head posture.[23] This was supported with the Spanish palaeontologist Jesús Marugán-Lobón and colleagues in a very 2013 research that advised the strategies employed by Sereno's staff were being imprecise, and that Nigersaurus habitually held its head like other sauropods.[24]
Nigersaurus lived in what is now the Sahara Desert throughout the mid-Cretaceous period, somewhere around 115 to one hundred and five million years in the past, in a lush, riverine habitat with considerable plant life.
Factors bought much more appealing in 1997. That is any time a member of Sereno's area crew found some Nigersaurus skull bones. Around the course of two expeditions, adequate substance was found to reconstruct about 80 % with the beast's skeleton.
Via a painstaking process, this crew was capable to reconstruct The within of Nigersaurus' cranium. That gave them a very good look at the lateral semicircular canal (LSC) of the inner ear, which aids animals continue to keep their balance.
