" This stems from the misinterpretation of its title, which is derived in the country of Niger, not a derogatory expression.
Nigersaurus (/niːˈʒɛərsɔːrəs, ˈnaɪdʒərsɔːrəs/) is really a genus of rebbachisaurid sauropod dinosaur that lived during the center Cretaceous period, about 115 to 105 million yrs ago. It absolutely was learned while in the Elrhaz Formation in a location known as Gadoufaoua, in Niger.
What Lots of people You should not know is usually that Paul Sereno didn't really find out this dinosaur; the scattered remains of Nigersaurus (in northern Africa's Elrhaz formation, in Niger ) ended up explained by a French paleontologist in the late 1960's and launched to the whole world in a very paper printed in 1976. Sereno did, having said that, have the distinction of naming this dinosaur (after studying extra fossil specimens) and publicizing it to the globe at substantial.
“This is the very first sauropod which has a tooth battery,” Sereno says, introducing that its jaw would've been angled downwards rather then forwards — And that's why Sereno had these types of difficulty fitting the bones together in the beginning.
On The idea of microtomography scans of cranium components of your holotype specimen, Sereno and colleagues established a "prototype" Nigersaurus skull they may study. In addition they designed an endocast of your Mind and scanned the semicircular canals of its interior ear, which they observed for being oriented horizontally. In their 2007 research, they stated that the structure of the occiput behind the cranium and cervical vertebrae would've minimal the upward and downward movement on the neck along with the rotation with the cranium.
” Our to start with 7 days in the field has been spectacular! Exceptional discoveries seem to be looking forward to us all around just about every dune. On our very first working day, we identified bones in the extended-necked dinosaur Nigersaurus. Nigersaurus, you could don't forget, we named for bones gathered on the last expedition here a few many years ago.
Judging from the LSC orientation in Nigersaurus, Sereno and organization hypothesized that the animal usually walked all-around with its snout pointed to the bottom in a 67-diploma angle. Photo a moping teenager and you'll get The theory.

This revelation arises from the fact that, Even with its elongated nostrils, the olfactory (smelling) region of its brain was reasonably smaller for its size. 11. Nigersaurus could in all probability see approximately 360 levels while feeding

Nevertheless it had significant nostrils as well as a fleshy snout, Sereno and colleagues uncovered that Nigersaurus had an underdeveloped olfactory area of its Mind and thus didn't have a complicated sense of odor. Its Mind-to-entire body-mass ratio was regular for a reptile, and more compact than Those people of ornithischians and non-coelurosaurian theropods. The cerebrum comprised about 30% on the Mind quantity, as in a number of other dinosaurs.[three] The American palaeoartist Mark Hallett and paleontologist Mathew J.
The immediate tooth substitution implies that it mainly fed on soft, abrasive vegetation, which might dress in down its teeth quickly.
Fossils of this dinosaur have been initial explained in 1976, but it absolutely was only named Nigersaurus taqueti in 1999, just after further more plus much more comprehensive continues to be were uncovered and described. The genus identify suggests "Niger reptile", and the particular identify honours the palaeontologist Philippe Taquet, who discovered the first continues what dinosaur has 500 teeth to be.
This intriguing variation showcases the assorted approaches dinosaurs created to prosper within their environments. The Nigersaurus’s swift tooth replacement, taking place every 14 days, can be extraordinary, environment it in addition to other sauropods that had slower tooth turnover.
