The Air Evident Nigersaurus stayed beneath the radar for very some time. The very first identified fossils belonging to this animal had been recovered over the fifties by French paleontologists in the Nigerian Sahara. Sadly, Many of these bones had been isolated or fragmentary.
It lived in a riparian habitat, and its diet regime in all probability consisted of soft crops, including ferns, horsetails, and angiosperms. It's One of the more frequent fossil vertebrates uncovered in the area, and shared its habitat with other dinosaurian megaherbivores, and big theropods and crocodylomorphs.
Yet a 3rd sauropod, the South American Antarctosaurus, might or might not are already a kissing cousin too.
Dinosaurs Have a very new relatives tree. Learn how it's adjusted and what The brand new tree reveals about dinosaurs' origins and evolution.

In 1997, when paleontologist Paul Sereno first began to unearth the remains of the dinosaur in Niger's Sahara Desert, he didn’t know what to Believe. He was excavating bones in the dry area referred to as Gadoufaoua, which experienced a rich fossil mattress first uncovered by French uranium miners.
We very carefully brushed the sand from the a hundred and ten million-12 months-outdated bones and dug channels concerning the main regions of the skeleton. Before long We're going to deal with Just about every space in plaster so which the skeleton is usually transported out of the sector and back again to your laboratory.
Nigersaurus are famous dinosaurs for having five hundred slender teeth inside their jaw. These dinosaurs are regarded not too long ago within the 12 months 2000 and ended up named in the distinction of state “Niger”. The term Nigersaurus has two sections; Niger (region name), and Saurus (reptile).
The teeth’s distinctive shape and arrangement have been flawlessly fitted to its feeding behaviors. The slender, chisel-like teeth could effectively snip off gentle vegetation, and their speedy substitute ensured the dinosaur could continually feed without having awaiting new teeth to develop.
Due to the fact quite a few rebbachisaurids inhabited latitudes that may are actually tropical to subtropical in the Middle Cretaceous, this pneumaticity might have assisted the animals cope Using the incredibly superior temperatures. In keeping with Ibiricu and colleagues, this adaptation could be a cause why rebbachisaurids have been the sole group of diplodocoids that survived to the Late Cretaceous.[21]
The fragile character with the Nigersaurus’s slender teeth and sensitive cranium designed excavation and preservation particularly difficult. Nonetheless, these what dinosaur has 500 teeth worries were met with progressive tactics in fossil Restoration and 3D reconstruction, making it possible for scientists to piece together the intricate details of its jaw and the astonishing array of 500 teeth.
It had a brief neck for just a sauropod, with thirteen cervical vertebrae. Almost all rebbachisaurids experienced comparatively small necks as well as a duration of 10 m (33 ft) or a lot less. The only real member of the household that achieved the dimensions of larger sauropods was
Nigersaurus did not show the exact same modifications witnessed while in the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing functions. The decrease jaw was L-shaped and divided in to the subcylindrical transverse ramus, which contained the teeth, along with the again ramus, which was additional lightweight and was the location for most of the muscle mass attachments. It absolutely was unique in that the tooth row expanded to the edges with the aircraft of the primary ramus of the reduce jaw.
In 2017, the Argentinian palaeontologist Lucio M. Ibiricu and colleagues examined the postcranial skeletal pneumaticity in the skeletons of rebbachisaurids, and suggested that it absolutely was an adaptation for reducing the density from the skeleton, and this might have reduced the muscle Vitality required to transfer your body, and also the heat created in the method.
