A 2009 review from the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was in the position to feed Together with the downturned head and neck posture proposed because of the 2007 research, but contested this was the habitual posture from the animal. The analyze pointed out the "neutral" head and neck posture of recent animals doesn't automatically correspond for their habitual head posture.
Nigersaurus didn't show the exact same modifications noticed inside the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing capabilities. The lessen jaw was L-shaped and divided in to the subcylindrical transverse ramus, which contained the teeth, as well as the back ramus, which was a lot more lightweight and was The placement for most of the muscle attachments. It had been unique in the tooth row expanded to the edges from the aircraft of the key ramus in the lessen jaw.
Nigersaurus is thought to own lived in massive herds and could have migrated above prolonged distances in quest of food stuff.
“Here is the 1st sauropod that has a tooth battery,” Sereno suggests, including that its jaw would have been angled downwards rather then forwards — Which is the reason Sereno experienced this sort of difficulties fitting the bones with each other at first.
eight ft) in size and weighing about two tons. In spite of its modest sizing in comparison with other sauropods, it obtained attention as a consequence of its special anatomy, such as a broad muzzle resembling a vacuum cleaner and dental batteries consisting of numerous compact, needle-formed teeth arranged in columns.
Depending on this biomechanical Nigersaurus Examination, the workforce concluded that the head and muzzle were habitually oriented 67° downwards and shut to floor amount, being an adaptation for ground-stage searching. That is as opposed to just how other sauropods have been restored, with their heads held more horizontally.[3]
The Nigersaurus, with its 500 teeth, showcases the marvels of evolution. Its specialized dental anatomy, personalized to its setting and diet program, serves to be a testament to the adaptability and diversity of prehistoric daily life.
We have an interest in finding much more than just dinosaurs. We want to discover all animals and plants that once lived together The traditional streams and forests 110 million several years back. Just about the most popular fossils we encountered in the very first week of work belonged to an unlimited crocodile identified as Sarcosuchus.
The reconstructed skeleton of an incredibly Bizarre dinosaur, the plant-eating Nigersaurus. This is the sculptural rendition of what the scientists count on the dinosaur's unique head could possibly have appeared like.
Nigersaurus is ideal recognized for its distinct cranium and jaw, which contained about 500 slender teeth organized in tightly packed rows. These teeth have been specialised for grazing on lower-lying vegetation, creating Nigersaurus a really productive herbivore.
The identify "Nigersaurus" has started controversy and discussion while in the scientific Group and outside of on account of its possible for misinterpretation and unintended connotations.
In 2020, the French palaeontologist Julien Benoit and colleagues analyzed lateral semicircular canal correlation to go posture on contemporary mammals, and found that though there was major correlation between the reconstructed and true head postures, the plane with the semicircular canal wasn't held horizontally while in the resting pose as inferred.

Using evidence from CT scans and 3D/Laptop modeling, scientists have determined that the sauropod very likely habitually held its head downwards, toward the ground — Despite the fact that this is hotly debated.
