In 2020, the French palaeontologist Julien Benoit and colleagues examined lateral semicircular canal correlation to go posture on modern day mammals, and located that even though there was considerable correlation involving the reconstructed and genuine head postures, the airplane in the semicircular canal was not held horizontally in the resting pose as inferred.
They consisted of vertically stacked columns of replaceable teeth. Every time the best tooth wore out in any provided column, the just one right underneath it would go upwards and go ahead and take outdated tooth's location.

It can be thought that these sauropod dinosaurs collected food utilizing their large, broad mouths, just like grazing in modern day cows. They'd very likely have already been “nonselective” inside their diet regime. two. Nigersaurus was one of several very first dinosaurs to secure a CT scan

‘ cranium was increased and located farther higher than the muzzle in comparison to other sauropods. This implies that its Visible fields overlapped, resulting in a in close proximity to 360-degree subject of look at (very similar to contemporary cows).
Following the iguanodontian Lurdusaurus, Nigersaurus was essentially the most numerous megaherbivore. Other herbivores through the identical development contain Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. Together, these compose one of several couple of associations of megaherbivores that has a stability of sauropods and enormous ornithopods.
Wedel and stated in 2016 that even though sauropods on the whole could use their extended necks to detect predators from afar, This could not apply into the small-necked Nigersaurus. They pointed out which the eyes of Nigersaurus ended up positioned even more to the highest from the skull than for most other sauropods, previously mentioned the muzzle, which would give it overlapping fields of perspective. Its Visible discipline would have been at or near 360 degrees, and hypersensitivity of motion would have been vital that you a vulnerable prey-animal.[20]
Paleontologist Paul Sereno explained Nigersaurus as “the weirdest dinosaur I’ve at any time noticed” if the dinosaur’s unusual functions have been 1st learned in 2007. The teeth were being significantly noteworthy since they had been organized in dental batteries, which are typically located in beaked herbivores like Triceratops and Edmontosaurus, but are what dinosaur has 500 teeth rare between sauropods.
1 for one of the most distinct options from the Nigersaurus was its teeth. It's 500 teeth! They ended up peg-like and tailored for grazing on crops.
Teeth at distinctive development stages, Museo di Storia Naturale di Venezia The slender teeth experienced marginally curved tooth crowns, which were oval in cross-portion. The crowns have been distinctive in obtaining notable ridges over the margins of their midline and sides. The teeth inside the decrease jaw might are actually 20–30% scaled-down than These during the upper jaw, but couple are acknowledged, and they are of unsure maturity. In addition to this, the teeth had been equivalent.[4] Underneath Each and every Lively tooth there was a column of nine alternative teeth within the jaw.
Paleontologists believe that their habits is often compared with now’s cows. Nigersaurus were being social and remained herds as a safety approach. Resulting from insufficient fossil evidence, the replica tactic of Nigersaurus is not identified.
‘ humorous-searching cranium, battery of teeth, and little dimension to get a sauropod have unquestionably won it a spot within the annals of dinosaur oddities.
The sauropod dinosaur Nigersaurus likely evolved its strangely-shaped head to better mow prehistoric lawns.
