The realm that Nigersaurus roamed all Those people an incredible number of a long time ago could are idyllic in selected methods, nonetheless it wasn't without having its lots of considerable potential risks.
The many tooth columns in Nigersaurus' dental batteries have been lined up, contrary to the teeth of other dinosaurs, at the quite entrance of its mouth, positioned along the muzzle's Carefully curved outer edge.
Yet a third sauropod, the South American Antarctosaurus, may or may not are already a kissing cousin at the same time.
Nigersaurus is an important discovery for paleontologists because it helps to get rid of mild around the evolution and variety of sauropods in the mid-Cretaceous period.
On The idea of microtomography scans of cranium elements of the holotype specimen, Sereno and colleagues produced a "prototype" Nigersaurus cranium they might analyze. They also created an endocast on the brain and scanned the semicircular canals of its inner ear, which they uncovered to get oriented horizontally. Within their 2007 analyze, they said the structure in the occiput at the back of the cranium and cervical vertebrae might have minimal the upward and downward motion of the neck and also the rotation of the skull.
Its exceptional dental construction implies that it could possibly have experienced a different feeding system when compared with other sauropods, and its existence in Africa implies that these kind of dinosaurs had been 500 teeth dinosaur more widespread than Beforehand considered.
Once the iguanodontian Lurdusaurus, Nigersaurus was probably the most numerous megaherbivore. Other herbivores from your identical formation contain Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. Together, these compose on the list of couple of associations of megaherbivores which has a stability of sauropods and enormous ornithopods.
We are interested in finding much more than simply dinosaurs. We want to find all animals and plants that once lived alongside the ancient streams and forests one hundred ten million years ago. The most prevalent fossils we encountered in the 1st 7 days of work belonged to an infinite crocodile named Sarcosuchus.
A 2009 review because of the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was capable to feed With all the downturned head and neck posture proposed by the 2007 study, but contested this was the habitual posture with the animal. The analyze famous the "neutral" head and neck posture of contemporary animals will not necessarily correspond for their habitual head posture.
A person for essentially the most distinctive attributes on the Nigersaurus was its teeth. It's five hundred teeth! They ended up peg-like and tailored for grazing on crops.
Greater nonetheless, These tooth columns have been packed ideal together with each other—like canned sardines. So a dinosaur armed with dental batteries could comfortably household quite a few hundred teeth (old and new) inside of its mouth.

Points received additional intriguing in 1997. Which is when a member of Sereno's subject workforce discovered some Nigersaurus cranium bones. Above the study course of two expeditions, enough substance was discovered to reconstruct about eighty p.c from the beast's skeleton.
Employing evidence from CT scans and 3D/Laptop modeling, scientists have identified that the sauropod probably habitually held its head downwards, toward the ground — Despite the fact that This really is hotly debated.
