Nigersaurus and its closest relations are grouped throughout the subfamily Rebbachisaurinae (formerly considered grouped inside the eponymous Nigersaurinae) on the family members Rebbachisauridae, and that is A part of the sauropod superfamily Diplodocoidea. Nigersaurus was possibly a browser, and fed with its head near the ground. The region of its brain that detected scent was underdeveloped, Whilst its brain measurement was akin to that of other dinosaurs.
Wafer-skinny fossils with thin bone plates are not the best issues to protect and research. But dag nabit, anyone's gotta do it!
Judging from the LSC orientation in Nigersaurus, Sereno and company hypothesized which the animal typically walked close to with its snout pointed to the ground in a 67-diploma angle. Photograph a moping teenager and you will get The thought.

While it experienced significant nostrils and also a fleshy snout, Sereno and colleagues uncovered that Nigersaurus had an underdeveloped olfactory location of its Mind and therefore did not have an advanced sense of scent. Its brain-to-entire body-mass ratio was ordinary for just a reptile, and lesser than All those of ornithischians and non-coelurosaurian theropods. The cerebrum comprised about 30% from the Mind quantity, as in a number of other dinosaurs.[3] The American palaeoartist Mark Hallett and paleontologist Mathew J.
What's much more, just like grazing cows today, these creatures were being ample through their heyday. Once the Original discovery, Sereno found A different Nigersaurus specimen through an expedition in 2000.
These teeth were being also replaceable (like sharks’ teeth), this means Nigersaurus constantly required clean teeth as more mature ones were being worn down or misplaced.
A 2015 cladistic study by Wilsona plus the French palaeontologist Ronan Allain discovered Rebbachisaurus alone to group Using the nigersaurines, and also the authors recommended that Nigersaurinae was hence a junior synonym of Rebbachisaurinae (given that that title would have precedence).
The cranium of a Nigersaurus was product of thin bones and had a lot of smaller openings and pores. These options provided them fantastic adaptability in feeding on the ground. The muzzle of the Nigersaurus was broad and prolonged which assisted it in feeding on compact floor-centered vegetation.
Just about the most Nigersaurus distinct features of Nigersaurus was its rows of tiny, peg-like teeth, which have been organized in a straight line along the front of its jaws. These teeth had been consistently replaced through the entire dinosaur’s lifestyle, making it possible for it to feed regularly on rough vegetation.
Skeletal diagram demonstrating recognized factors and dimension comparison Sereno and the American palaeontologist Jeffrey A. Wilson offered the 1st in-depth description in the skull and feeding adaptations in 2005.[1] In 2007, a far more specific description on the skeleton was released by Sereno ad colleagues, according to a specimen learned ten yrs earlier. The fossils, along with a reconstructed skeleton mount as well as a plastic design of The top and neck, have been subsequently offered for the Nationwide Geographic Society in Washington.
Horsetails (Equisetum) Possess a central, hollow stem with whorls of leaves or skinny branches. They keep their spores in the cigar-formed “cone” at the best of the plant. Horsetails date again to ~370 million a long time in the past. All through the start from the dinosaur period they grew to be nearly 30 ft tall (10m.)
Diplodocus cranium for comparison Its cranium was incredibly distinctive from Diplodocus, suggesting a unique feeding system. It experienced a lot of fenestrae (openings) and slim bones. It had a wide muzzle full of more than five hundred teeth.
