A 2009 research through the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was capable to feed Together with the downturned head and neck posture proposed from the 2007 analyze, but contested this was the habitual posture with the animal. The analyze observed that the "neutral" head and neck posture of recent animals will not always correspond to their habitual head posture.
Nigersaurus is a 30-foot-extended plant-ingesting dinosaur that lived a hundred and ten million years ago in what has become Niger’s Sahara Desert. Nigersaurus lived in the lush surroundings together with the predatory dinosaur Suchomimus, the plant eaters ouranosaurus and lurdusaurus, and supercroc. Nigersaurus had a delicate cranium and a particularly extensive mouth lined with teeth Primarily adapted for browsing plants close to the ground.
Only by bringing together vegetation from within the world and a number of fashionable environments can a dinosaur-age scene be recreated. A number of the crops, like ginkgos, look nearly similar to their extinct ancestors; some, just like the conifer Araucaria, have been the dominant trees on the forests a hundred and ten million a long time back.
The remains of Nigersaurus were being at first explained by Taquet in 1976 as belonging to the dicraeosaurid, but in 1999 Sereno and colleagues reclassified it to be a rebbachisaurid diplodocoid.[four] These scientists speculated that given that quick necks and compact measurement was regarded amid basal diplodocoids, it could indicate these had been ancestral functions from the group.
The Nigersaurus had exceptionally extended neck. It was about 2 times the duration of its system. This adaptation is thought to have evolved so that you can allow for Nigersaurus to succeed in higher amounts of vegetation. Nigersaurus also had an exceedingly modest head. It calculated only about thirty centimetres (12 inches) in width.
” Our 1st week in the field is breathtaking! Impressive discoveries appear to be watching for us around every dune. On our very first day, we identified bones in the lengthy-necked dinosaur Nigersaurus. Nigersaurus, you may bear in mind, we named for bones collected on the last expedition below a few yrs in the past.
This means that as 1 tooth wore 500 teeth dinosaur down or broke off, A different was ready to choose its location. This swift tooth replacement cycle, occurring somewhere around each individual 14 times, ensured that Nigersaurus generally had practical teeth to procedure its food stuff.
Nigersaurus also bears indications of small-angle tooth-to-tooth wear on the inside in the maxillary crowns, which implies that jaw movement was restricted to specific up-and-down motions. Worn teeth from the reduce jaw have not but been uncovered, but They can be predicted to point out opposing tooth-to-tooth wear. A chance to elevate their heads properly higher than the bottom would not always indicate they browsed on merchandise there, as well as the limited neck of Nigersaurus would've limited the browsing variety when compared with other diplodocoids.[three]
The lizard from Niger was a comparatively smaller sauropod, measuring close to nine meters (30 feet) in size and weighing about four tons. It had a lengthy neck and tail, with a short, slender snout which was tailored for browsing on reduced-lying vegetation.

Nigersaurus had issue in Keeping their head upward or horizontally. So eating leaves and also other parts of extended Trees was impossible for them.
was named and described in more element by Sereno and colleagues only in 1999, determined by continues to be of recently identified men and women. Precisely the same post also named
Nigersaurus did not exhibit a similar modifications found during the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing features. The reduce jaw was L-shaped and divided in the subcylindrical transverse ramus, which contained the teeth, plus the back again ramus, which was far more light-weight and was The placement for a lot of the muscle attachments. It absolutely was distinctive in the tooth row expanded to the sides with the aircraft of the primary ramus of the decreased jaw.
The authors for that reason cautioned from applying semicircular canals as proxy to infer the precise orientation of skulls. They discovered that diet program correlated strongly with semicircular canal orientation, although not with head posture, when head posture and semicircular canal orientation ended up strongly correlated with phylogeny.[twenty five]
