A 2009 analyze from the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was ready to feed with the downturned head and neck posture proposed with the 2007 study, but contested that this was the habitual posture in the animal. The analyze pointed out that the "neutral" head and neck posture of recent animals does not always correspond for their habitual head posture.
Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is usually a genus of rebbachisaurid sauropod dinosaur that lived all through the center Cretaceous time period, about one hundred fifteen to 105 million years back. It had been uncovered within the Elrhaz Development in an area referred to as Gadoufaoua, in Niger.

The Nigersaurus experienced particularly extended neck. It was about twice the duration of its system. This adaptation is assumed to possess evolved so that you can allow for Nigersaurus to achieve increased amounts of vegetation. Nigersaurus also experienced an exceptionally modest head. It measured only about 30 centimetres (twelve inches) in width.

Following the iguanodontian Lurdusaurus, Nigersaurus was probably the most many megaherbivore. Other herbivores from the similar formation include things like Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. With each other, these compose on the list of handful of associations of megaherbivores using a equilibrium of sauropods and enormous ornithopods.
On The idea of microtomography scans of skull elements with the holotype specimen, Sereno and colleagues designed a "prototype" Nigersaurus cranium they might examine. They also made an endocast on the brain and scanned the semicircular canals of its interior ear, Nigersaurus which they located to generally be oriented horizontally. In their 2007 analyze, they stated that the framework of the occiput behind the cranium and cervical vertebrae would have constrained the upward and downward motion in the neck and also the rotation in the cranium.
The teeth’s exceptional condition and arrangement were being perfectly fitted to its feeding patterns. The slender, chisel-like teeth could successfully snip off tender vegetation, and their quick replacement ensured that the dinosaur could repeatedly feed without the need of expecting new teeth to mature.
The most distinctive capabilities of Nigersaurus was its mouth, which was equipped with a huge selection of compact, tightly packed teeth arranged in rows. This permitted it to competently crop and grind hard plant make any difference, including ferns and horsetails.
This bizarre, extended-necked dinosaur is characterised by its unusually wide, straight-edged muzzle tipped with in excess of 500 replaceable teeth. The initial fossil cranium of Nigersaurus is amongst the to start with dinosaur skulls to generally be digitally reconstructed from CT scans.
Horsetails (Equisetum) have a central, hollow stem with whorls of leaves or thin branches. They hold their spores in a very cigar-formed “cone” at the highest on the plant. Horsetails date back again to ~370 million a long time ago. Throughout the beginning of your dinosaur period they grew being just about thirty ft tall (10m.)
