The region that Nigersaurus roamed all those many a long time back may have already been idyllic in specified approaches, but it wasn't with out its numerous substantial risks.
Named following the state of Niger, where by its fossils were very first identified. The name was picked to replicate its origins, however, the similarity in pronunciation to your racial slur has lifted fears about cultural sensitivity and appropriate terminology.
Life restoration Nigersaurus was distinct in that its dorsal (back) vertebrae had paired pneumatic spaces at the base of the neural spines (the spines that projected upwards from your vertebrae). The presacral vertebrae (vertebrae in front of the sacrum) have been greatly pneumatised to The purpose exactly where the column consisted of the series of hollow "shells", Each and every divided by a skinny septum in the center. It experienced small to no cancellous bone, producing the centra skinny bone plates stuffed with air spaces. The vertebral arches had been so seriously pierced by extensions with the external air sacs that in their facet partitions little remained but 2 mm (0.
It truly is believed that these sauropod dinosaurs collected foodstuff applying their large, broad mouths, much like grazing in modern day cows. They might probable have been “nonselective” in their food plan. two. Nigersaurus was one of several initial dinosaurs to acquire a CT scan
The Nigersaurus experienced particularly extensive neck. It had been about 2 times the duration of its human body. This adaptation is thought to have advanced so that you can allow for Nigersaurus to succeed in better amounts of vegetation. Nigersaurus also had an incredibly modest head. It measured only about 30 centimetres (12 inches) in width.
‘ skull was bigger and Situated farther higher than the muzzle when compared to other sauropods. This suggests that its visual fields overlapped, causing a near 360-degree subject of view (very similar to modern-day cows).
However, this claim continues to be contested by other researchers who imagine Nigersaurus was in all probability extra typical of other sauropods.

These common dinosaur reconstructions through the 1960s are no longer scientifically exact. Can you see the problems?
And what a skeleton it what dinosaur has 500 teeth absolutely was! 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.
This permitted the dinosaur to own a continuing supply of fresh new teeth, allowing for it to carry on to successfully process plant materials at the same time as its teeth have on down.
Wedel and mentioned in 2016 that although sauropods generally could use their long necks to detect predators from afar, This is able to not implement towards the short-necked Nigersaurus. They identified which the eyes of Nigersaurus were being positioned more towards the top from the cranium than in many other sauropods, higher than the muzzle, which would give it overlapping fields of watch. Its visual industry would've been at or near 360 levels, and hypersensitivity of movement would've been essential to a vulnerable prey-animal.[twenty]
Nigersaurus did not exhibit exactly the same modifications found inside the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing functions. The decrease jaw was L-shaped and divided into your subcylindrical transverse ramus, which contained the teeth, plus the back again ramus, which was more lightweight and was The situation for almost all of the muscle attachments. It was distinctive in that the tooth row expanded to the sides within the aircraft of the primary ramus of the decrease jaw.
Nigersaurus was probably a browser, and fed with its head close to the bottom. The region of its Mind that detected smell was modest, although its brain size was akin to that of other dinosaurs. There has been discussion on regardless of whether its head was habitually held downwards, or horizontally like other sauropods.
