The dinosaur's vertebrae was stuffed with air pockets similar to Those people of birds, Hence the dinosaur was most likely quite light, at the same time. Its brain was concerning the sizing of a walnut, which is roughly typical for sauropods, Sereno suggests.
Dinosaur-hunters are accustomed to acquiring dental batteries in beaked herbivores just like the horned Triceratops and shovel-billed Edmontosaurus. Nevertheless they're scarce Amongst the sauropods.
Initial discoveries of Nigersaurus fossils day back again into the 1960s, nevertheless it was not right until the 1970s that far more comprehensive remains had been uncovered. These remains ended up formally examined and described by paleontologist Paul Sereno and his team in 1999.

Because of this as 1 tooth wore down or broke off, another was ready to take its put. This rapid tooth replacement cycle, taking place roughly every fourteen times, ensured that Nigersaurus normally experienced practical teeth to method its food stuff.
Even though it experienced huge nostrils plus a fleshy snout, Sereno and colleagues found that Nigersaurus had an underdeveloped olfactory area of its brain and therefore did not have a sophisticated perception of scent. Its brain-to-body-mass ratio was typical for the reptile, and smaller sized than Individuals of ornithischians and non-coelurosaurian theropods. The cerebrum comprised about 30% of the brain quantity, as in all kinds of other dinosaurs.[three] The American palaeoartist Mark Hallett and paleontologist Mathew J.
When Taquet in the beginning explained the dinosaur’s continues to be in the nineteen seventies, the official classification and naming were being conducted many years afterwards by Sereno, emphasizing the collaborative nature of its examine and discovery.
The dental constructions of Nigersaurus also counsel which they ate gentle crops in substantial quantities to fulfill their nutritional requirements. They mostly ate angiosperms, horsetails, and ferns as food stuff. Numerous paleontologists also believe that their 500 closely packed teeth arrangement also functioned similar to a comb. This comb-like teeth arrangement could possibly have also aided them in filtering and feeding on aquatic crops.
The restricted knowledge of the genus was the result of lousy preservation of its remains, which arises in the sensitive and very pneumatic design (crammed with air spaces linked to air sacs) on the skull and skeleton, subsequently causing disarticulation with the fossils. A lot of the cranium fossils had been so skinny that a powerful mild beam was noticeable by means of them. As a result, no intact skulls or articulated skeletons have already been discovered, and these specimens depict the most full acknowledged rebbachisaurid remains.[three][one]
” Our to start with 7 days in the sphere has actually been spectacular! Outstanding discoveries seem to be awaiting us all-around every dune. On our initial day, we found bones from the extended-necked dinosaur Nigersaurus. Nigersaurus, you could bear in mind, we named for bones gathered on the final expedition below 3 yrs back.
These well-liked dinosaur reconstructions from the sixties are not scientifically exact. Can you notice the mistakes?
Nigersaurus can be a 30-foot-extensive plant-ingesting dinosaur that lived one hundred ten million yrs back in what Nigersaurus is currently Niger’s Sahara Desert. Nigersaurus lived in the lush surroundings alongside the predatory dinosaur Suchomimus, the plant eaters ouranosaurus and lurdusaurus, and supercroc. Nigersaurus experienced a fragile skull and an extremely large mouth lined with teeth In particular tailored for searching vegetation close to the bottom.
The snout was also proportionately shorter, and also the tooth row was under no circumstances prognathous, the snout suggestion not protruding relative to the remainder of your tooth sequence.[one] Nigersaurus was distinct in that its frontal bone (which formed Substantially from the cranium-roof) was elongate (much narrower than prolonged), and experienced a marked cerebral fossa (a depression to the surface of the bone Within the head).[four] The maxillary tooth row was in its entirety transversely rotated, its regular rear 90° everted toward the entrance. This was matched by A similar rotation from the dentary on the lessen jaw. This transverse orientation from the upper and decrease tooth rows was one of a kind to the dinosaur. On account of this configuration, no other tetrapod had all of its teeth Positioned as considerably towards the front as Nigersaurus.[three][4]
The swift tooth replacement implies that it mainly fed on soft, abrasive plants, which might don down its teeth swiftly.
