The name "Nigersaurus" has begun controversy and discussion during the scientific Neighborhood and outside of as a consequence of its probable for misinterpretation and unintended connotations.
Nigersaurus is really a thirty-foot-extensive plant-eating dinosaur that lived 110 million decades ago in what is now Niger’s Sahara Desert. Nigersaurus lived within a lush natural environment along with the predatory dinosaur Suchomimus, the plant eaters ouranosaurus and lurdusaurus, and supercroc. Nigersaurus experienced a delicate cranium and a very vast mouth lined with teeth especially tailored for browsing plants near to the bottom.
What Lots of people Will not know is usually that Paul Sereno failed to actually uncover this dinosaur; the scattered remains of Nigersaurus (in northern Africa's Elrhaz formation, in Niger ) were described by a French paleontologist inside the late 1960's and released to the world in a very paper posted in 1976. Sereno did, however, have the honor of naming this dinosaur (following researching additional fossil specimens) and publicizing it to the planet at huge.
But that’s not all for Nigersaurus. Chris took us all to some flat location of purple-colored sandstone in which he experienced Positioned the upper jaw of a newborn Nigersaurus—just one that will healthy on top of a silver greenback!

lived in what has become Niger about 115 to one hundred and five million yrs back, in the course of the Aptian and Albian ages from the mid-Cretaceous. It probable lived in habitats dominated by inland floodplains (a riparian zone).
Eventually, back again within the lab, Sereno needed to ask for a 2nd viewpoint from colleagues who worked on fossil fish and other reptiles ahead of he figured it out.
We are not discussing AA Duracells in this article. Dental batteries were being successful food items processing instruments utilized by several plant-ingesting dinos.
A 2015 cladistic analyze by Wilsona along with the French palaeontologist Ronan Allain observed Rebbachisaurus itself to team with the nigersaurines, and the authors prompt that Nigersaurinae was hence a junior synonym of Rebbachisaurinae (due to the fact that title would've precedence).
And what a skeleton it had been! The newfound fossils gave us our to start with look at the dino's complex dental batteries and vacuum cleaner mouth. Sereno named the species Nigersaurus taqueti — as an homage to French paleontologist Philippe Taquet — in 1999.
However it had massive nostrils and a fleshy snout, Sereno and colleagues observed that Nigersaurus had an underdeveloped olfactory region of its Mind and thus didn't have a complicated feeling of odor. Its Mind-to-entire body-mass ratio was common for any reptile, and lesser than Individuals of ornithischians and non-coelurosaurian theropods. The cerebrum comprised about 30% of your brain quantity, as in a number of other dinosaurs.[3] The American palaeoartist Mark Hallett and paleontologist Mathew J.
In 2020, the French palaeontologist Julien Benoit and colleagues tested lateral semicircular canal correlation to move posture on modern-day mammals, and located that although there was considerable correlation in between the reconstructed and precise head postures, the plane of your semicircular canal wasn't held horizontally while in the resting pose as inferred.
Even though the nasal bones are usually not completely acknowledged, it seems the entrance margin of the bony nostril was nearer to the snout than in other diplodocoids. The snout was also proportionately shorter, plus the tooth row was not at all prognathous, the snout suggestion not protruding relative to the remainder with the tooth series. The maxillary tooth row was in its entirety transversely rotated, its regular rear 90° everted in the direction of the front. This was matched by A similar rotation on the dentary 500 teeth dinosaur from the lessen jaw. Therefore, no other tetrapod experienced all of its teeth Situated as considerably to the entrance as
In 2017, the Argentinian palaeontologist Lucio M. Ibiricu and colleagues examined the postcranial skeletal pneumaticity within the skeletons of rebbachisaurids, and proposed that it absolutely was an adaptation for decreasing the density on the skeleton, and that this could have decreased the muscle mass Electrical power required to go the body, as well as the warmth created in the procedure.
