A 2009 examine via the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was in the position to feed With all the downturned head and neck posture proposed from the 2007 research, but contested this was the habitual posture in the animal. The study observed that the "neutral" head and neck posture of recent animals will not essentially correspond for their habitual head posture.
However the nasal bones will not be fully identified, it appears the front margin of your bony nostril was closer on the snout than in other diplodocoids. The snout was also proportionately shorter, as well as tooth row was by no means prognathous, the snout idea not protruding relative to the remainder from the tooth collection. The maxillary tooth row was in its entirety transversely rotated, its ordinary rear 90° everted towards the entrance. This was matched by An analogous rotation in the dentary of your decrease jaw. Consequently, no other tetrapod had all of its teeth located as considerably into the entrance as
We have been closing in on that intention quickly since we arrived upon a skeleton a few days later on! This skeleton is lying on its aspect Along with the tail curved upward. The curve of the backbone steps about 15 toes.
But that’s not all for Nigersaurus. Chris took us all to a flat space of purple-coloured sandstone wherever he had Found the upper jaw of the newborn Nigersaurus—one that may suit along with a silver dollar!

Nigersaurus didn't show the identical modifications seen during the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing capabilities. The lessen jaw was L-shaped and divided to the subcylindrical transverse ramus, which contained the teeth, as well as the back again ramus, which was a lot more light-weight and was the location for almost all of the muscle mass attachments. It absolutely was distinct in that the tooth row expanded to the edges in the plane of the main ramus from the decreased jaw.
Sauropod dinosaurs, like Nigersaurus, walked on four legs, having a very long “whiplash tail” and a lengthy neck. But in comparison with other sauropods, it absolutely was fairly smaller — sitting somewhere amongst an African and Indian elephant in dimension.
lived in what is currently Niger about one hundred fifteen to a hundred and five million years ago, in the course of the Aptian and Albian ages of the mid-Cretaceous. It very likely lived in habitats dominated by inland floodplains (a riparian zone).
As it was a prey animal, it absolutely Nigersaurus was critical for Nigersaurus to get motion hypersensitivity to detect any probable threats.
Nigersaurus is thought to behave much like other herbivore sauropods. They had almost certainly expended most in their time in hang-dog positions and grazing minimal-lying vegetation.
Nigersaurus are renowned dinosaurs for possessing 500 slender teeth within their jaw. These dinosaurs are already recognized recently from the year 2000 and were named in the dignity of country “Niger”. The phrase Nigersaurus has two sections; Niger (place title), and Saurus (reptile).
The restricted comprehension of the genus was the results of lousy preservation of its remains, which arises through the sensitive and remarkably pneumatic design (crammed with air spaces connected to air sacs) from the cranium and skeleton, consequently producing disarticulation of your fossils. Some of the cranium fossils had been so skinny that a powerful mild beam was obvious through them. Consequently, no intact skulls or articulated skeletons have already been identified, and these specimens characterize quite possibly the most complete known rebbachisaurid remains.[three][1]
Nonetheless, as stated, Nigersaurus experienced a relentless source of new teeth as they had been replaced once the prime tooth in a column wore out.
The nickname "dinosaur with 500 teeth" emanates from Nigersaurus's exclusive dental battery. Its jaw held about 500 slender teeth, arranged in tightly packed rows, and these teeth ended up continually replaced all through its life.
