Working with evidence from CT scans and 3D/Laptop or computer modeling, researchers have decided that the sauropod probably habitually held its head downwards, toward the bottom — While This is often hotly debated.
Its head is what really stands out about Nigersaurus, although. The jaws, which have a flat front, are lined with about 500 teeth, which Sereno claims have been replaceable. These teeth have been all a similar in sizing, and he estimates which they in all probability only lasted about per month or so just before they have been worn down.
Judging because of the LSC orientation in Nigersaurus, Sereno and firm hypothesized that the animal ordinarily walked about with its snout pointed to the bottom at a 67-degree angle. Image a moping teenager and you'll get the idea.

Ongoing Tooth Substitute: Teeth were being replaced each and every fourteen days, guaranteeing a sharp, useful dental battery to cope with constant wear from grazing.
Nigersaurus, a rebbachisaurid sauropod from the middle Cretaceous interval, was uncovered in the Elrhaz Formation in Niger. Its title, meaning “Niger’s lizard,” was specified next the discovery of a lot more finish continues to be in 1999, although its fossils had been initial described in 1976.
Just like other Sauropods, Nigersaurus had been herbivores. They'd grazed near to the ground and ate reduced-lying vegetation. They'd a large muzzle which aided them in cropping additional vegetative content in one bite. It's possible you'll Imagine they probably ate grass, though the grass hadn’t evolved in the course of that point.
Nigersaurus had trouble in holding their head upward or horizontally. So consuming leaves and also other portions of extensive Trees was impossible for them.
A lot of Nigersaurus specimens gathered by French and American expeditions remain to become described.[nine] Teeth much like People of Nigersaurus have already been located around the Isle of Wight As well as in Brazil, but it is unfamiliar whether they belonged to family members of this taxon, or to titanosaurs, whose continues to be are present in the vicinity.
Nigersaurus was named once the West African nation wherever its fossils happen to be uncovered: The Republic of Niger. Back when this animal roamed, forests and braided rivers covered the landscape. (Nigersaurus would've had to Be careful for Sarcosuchus, a huge relative of contemporary crocodiles.)
The Nigersaurus is a fascinating and exclusive dinosaur which has captured prevalent notice, partly as a result of its unconventional attributes and intriguing nickname as being the "dinosaur with 500 teeth."
The jaws could have borne a keratinous sheath. In contrast to other tetrapods, the tooth-bearing bones of its jaws were rotated transversely relative to the remainder of the cranium, so that all of its teeth were being located much towards the front. Its skeleton was remarkably pneumatised (stuffed with air spaces linked to air sacs), nevertheless the limbs have been robustly developed.
The journey to uncover the secrets and techniques from the Nigersaurus began with the main fossil fragments discovered within the 1970s inside the Elrhaz Formation of Niger, nevertheless it wasn’t right up until 1999 that additional total continues to be introduced this interesting dinosaur into your Highlight. These discoveries introduced paleontologists with both of those worries and opportunities.
Diplodocus skull for comparison Its skull was incredibly distinct from Diplodocus, suggesting a distinct feeding strategy. It had quite a few fenestrae (openings) 500 teeth dinosaur and slender bones. It had a broad muzzle crammed with much more than five hundred teeth.
