At some point, again inside the lab, Sereno had to ask for a 2nd viewpoint from colleagues who labored on fossil fish and also other reptiles in advance of he figured it out.
The authors for that reason cautioned towards working with semicircular canals as proxy to infer the exact orientation of skulls. They uncovered that diet correlated strongly with semicircular canal orientation, but not with head posture, even though head posture and semicircular canal orientation were strongly correlated with phylogeny.[twenty five]
Its feeding design and style has become in comparison with that of recent grazing animals or even a vacuum cleaner, mainly because it probable swept its head side-to-aspect while consuming vegetation.

Like other sauropods, Nigersaurus had a lengthy neck and tail. Even so, its neck was comparatively short compared to other users of its group, aligning with its very low-grazing Life style. Its columnar legs supported its quadrupedal posture and helped bear its weight successfully.
As we’ve observed, Nigersaurus had a large muzzle and numerous teeth flawlessly suited to consuming lower-lying vegetation. This diet plan and Life-style might have required the creature to have a constant offer of substitute teeth, mainly because it would've worn out its tooth crowns swiftly. A review released in the journal PLOS One particular
Nigersaurus is known to get lived in what has become present day-working day Niger, Africa, consequently its name. It had been to start with uncovered during the early 2000s by a staff of paleontologists led by Paul Sereno.
The fast replacement 500 teeth dinosaur of its teeth, each fourteen times, indicates that the Nigersaurus faced significant evolutionary pressures to take care of a relentless provide of functional teeth to manage with abrasive plant product. This adaptation underlines the evolutionary vital to enhance feeding effectiveness in an ecosystem where by food items resources various and Level of competition was intense.
The name "Nigersaurus" has started controversy and dialogue from the scientific Local community and over and above because of its possible for misinterpretation and unintended connotations.
In 2020, the French palaeontologist Julien Benoit and colleagues examined lateral semicircular canal correlation to go posture on modern day mammals, and found that while there was major correlation concerning the reconstructed and precise head postures, the airplane of your semicircular canal wasn't held horizontally within the resting pose as inferred.
Skeletal diagram demonstrating recognized factors and dimensions comparison Sereno as well as American palaeontologist Jeffrey A. Wilson provided the very first in-depth description with the cranium and feeding adaptations in 2005.[one] In 2007, a far more detailed description of your skeleton was revealed by Sereno advert colleagues, based on a specimen found ten several years previously. The fossils, in addition to a reconstructed skeleton mount and also a plastic product of The pinnacle and neck, have been subsequently presented within the Nationwide Geographic Culture in Washington.
Only by bringing alongside one another vegetation from across the world and various contemporary environments can a dinosaur-age scene be recreated. A lot of the vegetation, like ginkgos, look just about the same as their extinct ancestors; some, similar to the conifer Araucaria, were being the dominant trees on the forests a hundred and ten million yrs ago.
The speedy tooth replacement suggests that it largely fed on tender, abrasive plants, which might use down its teeth quickly.
