Applying proof from CT scans and 3D/Laptop or computer modeling, researchers have determined which the sauropod very likely habitually held its head downwards, toward the bottom — Despite the fact that This can be hotly debated.
The authors as a result cautioned against making use of semicircular canals as proxy to infer the specific orientation of skulls. They discovered that diet regime correlated strongly with semicircular canal orientation, although not with head posture, whilst head posture and semicircular canal orientation were being strongly correlated with phylogeny.[twenty five]
Judging from the LSC orientation in Nigersaurus, Sereno and firm hypothesized that the animal usually walked around with its snout pointed to the bottom at a 67-diploma angle. Picture a moping teen and you'll get the idea.
But that’s not all; within just its oddly formed muzzle, the dinosaur was equipped without any below five hundred teeth (each “Lively” and substitution). The upper jaws contained 60 rows of smaller, needle-formed teeth, while the reduced jaws experienced no fewer than 68 extremely sharp teeth.

There have been discussion on no matter whether its head was habitually held downwards, or horizontally like other sauropods. It lived inside a riparian habitat, and its diet regime possibly consisted of soft crops, for example ferns, horsetails, and angiosperms. It is The most frequent fossil vertebrates found in the area, and shared its habitat with other dinosaurian megaherbivores, as well as substantial theropods and crocodylomorphs.
What's additional, similar to grazing cows right now, these creatures had been abundant all through their heyday. Once the Preliminary discovery, Sereno discovered A further Nigersaurus specimen through an expedition in 2000.
The dental buildings of Nigersaurus also propose they ate gentle crops in big quantities to satisfy their nutritional specifications. They primarily ate angiosperms, horsetails, and ferns as foodstuff. Several paleontologists also think that their 500 intently packed teeth arrangement also functioned similar to a comb. This comb-like teeth arrangement can have also aided them in filtering and taking in aquatic plants.
Nigersaurus experienced a jaw framework contrary to some other dinosaur. Its broad, squared-off muzzle housed around five hundred slender, pencil-like teeth. These teeth were not evenly dispersed but had been arranged in columns and rows, with as many as nine alternative teeth guiding Just about every Energetic tooth.
“It’s something that definitely normally takes the cake for remarkable cranial adaptations in this team, the prolonged-necked dinosaurs,” says Sereno, a professor of paleontology within the College of Chicago. “It’s simply a majestic illustration of evolution.”
In 2020, the French palaeontologist Julien what dinosaur has 500 teeth Benoit and colleagues tested lateral semicircular canal correlation to head posture on contemporary mammals, and found that while there was important correlation involving the reconstructed and genuine head postures, the plane from the semicircular canal was not held horizontally from the resting pose as inferred.
Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is usually a genus of rebbachisaurid sauropod dinosaur that lived in the course of the middle Cretaceous time period, about one hundred fifteen to one zero five million a long time in the past. It had been found from the Elrhaz Formation in a location called Gadoufaoua, in Niger.
Nigersaurus is thought from numerous partial skeletons and isolated bones, which have delivered precious information regarding its anatomy and actions.
We are interested find extra than just dinosaurs. We want to locate all animals and plants that once lived alongside the ancient streams and forests 110 million a long time ago. The most popular fossils we encountered in the first 7 days of work belonged to a massive crocodile termed Sarcosuchus.
