Dinosaur-hunters are utilized to getting dental batteries in beaked herbivores such as horned Triceratops and shovel-billed Edmontosaurus. But they're exceptional Amongst the sauropods.
Nigersaurus lived in what is now the Sahara Desert in the mid-Cretaceous time period, approximately a hundred and fifteen to a hundred and five million a long time ago, in a very lush, riverine habitat with plentiful vegetation.
Following the iguanodontian Lurdusaurus, Nigersaurus was probably the most numerous megaherbivore. Other herbivores in the very same formation incorporate Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. Collectively, these compose one of many several associations of megaherbivores by using a equilibrium of sauropods and enormous ornithopods.
It lived during a time if the area was coated in forests and braided rivers, and would have needed to Be careful to the existence of Sarcosuchus, a giant relative of modern crocodiles.
Sadly, this has triggered misunderstandings and occasional misuse in on-line conversations. Whilst the eye has sparked curiosity with regard to the dinosaur, Furthermore, it underscores the value of cultural sensitivity and exact conversation when speaking about scientific discoveries.
It absolutely was uncovered within the wealthy fossil vertebrate fauna of your Elrhaz Formation in an area identified as Gadoufaoua, in the Republic of Niger. Fossils of the dinosaur were 1st explained in 1976, but it was only named in 1999 soon after more comprehensive continues to be were observed and described.
Hans is dealing with a crew of Allison and Dave to excavate a new web site. As we dug within the skull, we uncovered One more juvenile cranium of the identical species lying suitable next to the large a person.
A 2015 cladistic examine by Wilsona and the French palaeontologist Ronan Allain located Rebbachisaurus itself to team Along with the nigersaurines, along with the authors recommended that Nigersaurinae was thus a junior synonym of Rebbachisaurinae (because that identify would have priority).
Nigersaurus also bears signs of small-angle tooth-to-tooth put on on The within with the maxillary crowns, which indicates that jaw motion was limited to precise up-and-down motions. Worn teeth from the reduced jaw haven't but been identified, but They are really expected to show opposing tooth-to-tooth wear. The chance to increase their heads well previously mentioned the bottom won't necessarily imply they browsed on things there, plus the small neck of Nigersaurus might have limited the browsing vary when compared with other diplodocoids.[3]
The mix of its specialised anatomy as well as the one of a 500 teeth dinosaur kind surroundings where it lived make it an intriguing issue of research for paleontologists.
What dinosaur has 500 teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert 110 million years back. These sauropod dinosaurs collected meals by using a huge, broad mouth; the snout was broader compared to the back again from the creature's head on the first fossil skull.
Having said that, as mentioned, Nigersaurus experienced a continuing offer of recent teeth since they had been replaced when the top tooth within a column wore out.
Diplodocus cranium for comparison Its cranium was quite diverse from Diplodocus, suggesting a unique feeding strategy. It had several fenestrae (openings) and skinny bones. It had a broad muzzle crammed with much more than five hundred teeth.
