The dinosaur's vertebrae was full of air pockets comparable to those of birds, And so the dinosaur was probably fairly gentle, also. Its brain was about the dimensions of the walnut, which can be more or less common for sauropods, Sereno states.
Nigersaurus probable employed its dental batteries to competently system very low-lying plants like ferns and horsetails, which it collected with its broad muzzle. It very likely fed at ground level due to its quick neck, and its teeth might have worn out swiftly from shearing through rough vegetation.
We've been a bunch of biologists and paleontologists, creating articles and well-known science publications that present the world of animals, vegetation and introduce the nuances of paleontology in an accessible way for visitors.
Our writers at Discovermagazine.com use peer-reviewed studies and higher-high quality sources for our articles or blog posts, and our editors critique for scientific precision and editorial benchmarks. Assessment the sources employed beneath for this informative article:
On The idea of microtomography scans of cranium things with the holotype specimen, Sereno and colleagues designed a "prototype" Nigersaurus cranium they might look at. They also made an endocast of your Mind and scanned the semicircular canals of its interior ear, which they located to get oriented horizontally. Within their 2007 review, they said the structure of the occiput in the back of the cranium and cervical vertebrae might have constrained the upward and downward movement of the neck as well as rotation with the skull.
This bizarre, extensive-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with much more than 500 replaceable teeth. The original fossil cranium of Nigersaurus is amongst the initial dinosaur skulls to be digitally reconstructed from CT scans.
These teeth have been specialised for competently cropping and grinding tender, small-lying vegetation. The dinosaur’s teeth were regularly replaced, with new kinds expanding each 14 days to maintain features.
Nigersaurus had difficulty in holding their head upward or horizontally. So taking in leaves and other areas of very long Trees was not possible for them.

Nigersaurus was named once the West African state exactly where its fossils were discovered: the Republic of Niger. In the course of this creature’s time, the landscape (now Portion of the Sahara Desert) is believed to are protected with forests and braided rivers.
The mix of its specialised anatomy and also the exceptional environment in which it lived help it become an interesting matter of study for paleontologists.
On The idea of microtomography scans of skull elements from the holotype specimen, Sereno and colleagues created a "prototype" Nigersaurus cranium they might analyze. Additionally they created an Nigersaurus endocast from the Mind and scanned the semicircular canals of its interior ear, which they discovered to get oriented horizontally. Within their 2007 research, they said which the framework in the occiput at the back of the skull and cervical vertebrae would've constrained the upward and downward movement of your neck plus the rotation in the skull.
Nigersaurus was named and described in additional element by Sereno and colleagues only in 1999, determined by continues to be of newly identified persons. The same report also named Jobaria, One more sauropod from Niger. The genus name Nigersaurus ("Niger reptile") is usually a reference on the country exactly where it had been uncovered, and the particular identify taqueti honours Taquet, who was the primary to organise massive-scale palaeontological expeditions to Niger.
The fragile nature on the Nigersaurus’s slender teeth and delicate cranium made excavation and preservation specifically hard. Still, these worries were satisfied with modern procedures in fossil Restoration and 3D reconstruction, allowing scientists to piece jointly the intricate facts of its jaw as well as astonishing array of 500 teeth.
