“It’s a thing that really usually takes the cake for awesome cranial adaptations In this particular team, the extended-necked dinosaurs,” suggests Sereno, a professor of paleontology within the College of Chicago. “It’s merely a majestic example of evolution.”
Since various rebbachisaurids inhabited latitudes that could are actually tropical to subtropical in the center Cretaceous, this pneumaticity may have assisted the animals cope Along with the pretty substantial temperatures. In keeping with Ibiricu and colleagues, this adaptation may be a cause why rebbachisaurids have been the only real group of diplodocoids that survived in the Late Cretaceous.[21]
Overall, Nigersaurus was a novel and unusual dinosaur resulting from its dental batteries and wide muzzle, which authorized it to proficiently method and Collect plant substance. Its smaller measurement and herbivorous diet program make it a fascinating distinction into the more substantial, carnivorous dinosaurs which might be much more frequently recognised to most people.
But that’s not all for Nigersaurus. Chris took us all to your flat place of purple-coloured sandstone wherever he had located the upper jaw of the baby Nigersaurus—one particular that would suit in addition to a silver greenback!
In Nigersaurus' scenario, the upper jaws contained sixty columns of little, needle-formed upper teeth. And no much less than 68 pretty sharp teeth had been existing about the lower jaws. Tallied with each other, higher jaw and reduced jaw, the beast had over 500 individual teeth.
Fossil evidence suggests it lived in what has become the Sahara Desert, feeding on ferns together with other vegetation in its lush, riverine habitat.
By having an astonishing 500 teeth, this dinosaur provides a singular glimpse into your evolutionary adaptations of prehistoric creatures. Allow’s investigate the whole world of your Nigersaurus and its fascinating dental anatomy.
On the basis of microtomography scans of cranium factors in the holotype specimen, Sereno and colleagues made a "prototype" Nigersaurus cranium they may take a look at. They also designed an endocast with the brain and scanned the semicircular canals of its internal ear, which they located to become oriented horizontally. Of their 2007 examine, they stated that the construction on the occiput in the back of the cranium and cervical vertebrae would've constrained the upward and downward motion with the neck as well as the rotation with the skull.
Paleontologist Paul Sereno explained Nigersaurus as “the weirdest dinosaur I’ve ever seen” in the event the dinosaur’s strange characteristics were first found out in 2007. The teeth were being specially noteworthy as they have been organized in dental batteries, which are generally present in beaked herbivores like Triceratops and Edmontosaurus, but are rare among sauropods.

Sad to say, this has led to misunderstandings and occasional misuse in on-line discussions. Though the attention has sparked curiosity in regards to the dinosaur, In addition it underscores the importance of cultural sensitivity and correct conversation when talking about scientific discoveries.
Like other sauropods, Nigersaurus had a protracted neck and tail. Nevertheless, its neck was somewhat brief when compared to other members of its group, aligning with its small-grazing Way of life. Its columnar legs supported its quadrupedal posture and assisted bear its bodyweight efficiently.
‘ amusing-hunting skull, battery of teeth, and compact dimensions for any sauropod have certainly gained it an area within the annals of dinosaur oddities.
In 2017, the Argentinian palaeontologist Lucio M. Ibiricu and colleagues examined the postcranial skeletal pneumaticity during the skeletons of rebbachisaurids, and prompt that it absolutely was an adaptation for reducing the density in the skeleton, and that this might have decreased the muscle Vitality required to shift your body, plus the heat generated in the procedure.
