A 2009 analyze through the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was able to feed Together with the downturned head and neck posture proposed because of the 2007 examine, but contested that this was the habitual posture from the animal. The review mentioned the "neutral" head and neck posture of recent animals would not always correspond for their habitual head posture.
A 2015 cladistic analyze by Wilsona and the French palaeontologist Ronan Allain identified Rebbachisaurus itself to group Together with the nigersaurines, as well as the authors advised that Nigersaurinae was consequently a junior synonym of Rebbachisaurinae (given that that name would have precedence).
In conclusion, Nigersaurus was a novel and interesting dinosaur that lived during the Late Cretaceous period of time in what is now Niger. Its rows of small teeth and specialised jaw framework built it nicely-suited for browsing on small-lying vegetation, and its fossils serve as a worthwhile supply of specifics of the variety of daily life that existed on Earth a lot of a long time back.
Nigersaurus lived one hundred ten million decades in the past in what is now Niger, West Africa. Even though the fossils ended up found in the Sahara Desert, when Nigersaurus lived the world was a floodplain with vast rivers, conifer forests and lush vegetation.
What dinosaur has 500 teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert one hundred ten million decades ago. These sauropod dinosaurs gathered foods with a massive, wide mouth; the snout was wider when compared to the again in the creature's head on the original fossil skull.
If correct, it would starkly contrast with most sauropod reconstructions, showing the animal holding its head horizontally.
Using an astonishing five hundred teeth, this dinosaur delivers a novel glimpse into your evolutionary adaptations of prehistoric creatures. Allow’s take a look at the entire world of the Nigersaurus and its fascinating dental anatomy.
Nigersaurus also bears indications of low-angle tooth-to-tooth put on on the inside on the maxillary crowns, which implies that jaw motion was restricted to specific up-and-down motions. Worn teeth from the lower jaw have not however been identified, but They can be anticipated to indicate opposing tooth-to-tooth use. The opportunity to elevate their heads perfectly higher than the ground doesn't automatically necessarily mean they browsed on things there, plus the shorter neck of Nigersaurus would have restricted the browsing selection when compared with other diplodocoids.[three]
A 2015 cladistic study by Wilsona plus the French palaeontologist Ronan Allain identified Rebbachisaurus alone to group Using the nigersaurines, and the authors instructed that Nigersaurinae was as a result a junior synonym of Rebbachisaurinae (since that title would have precedence).
Fossils of the dinosaur have been initially explained in 1976, but it absolutely was only named Nigersaurus taqueti in 1999, following additional and even more comprehensive stays ended up observed and explained. The genus title implies "Niger reptile", and the particular title honours the palaeontologist Philippe Taquet, who uncovered the 1st continues to be.
The large muzzle of Nigersaurus was very likely an adaptation to its reduced-lying herbivorous food plan, making it possible for it to easily scoop up and Assemble plant content from the ground.
Like other sauropods, Nigersaurus experienced an extended neck and tail. Having said that, its neck was fairly small in comparison with other users of its group, aligning with its very low-grazing lifestyle. Its columnar legs supported its quadrupedal posture and assisted bear its pounds efficiently.
The Nigersaurus initial fossils of Nigersaurus were being found in the Elrhaz Formation of Niger during the yr 1997. However, additional examine disclosed that Nigersaurus was truly a member of a different team of sauropods known as the rebbachisaurids.
Its shorter neck would have also been an adaptation to this ground-stage feeding actions, as it would not have already been ready to succeed in higher into trees like Various other sauropods.
