The secret lies inside the creature’s bones. Researchers may have found out more Nigersaurus fossils When the animal had not had these kinds of a fragile bone composition. According to a research by Sereno et al. 2007, this creature had an exceptionally lightweight cranium. Many of the bones in Nigersaurus

Many of the tooth columns in Nigersaurus' dental batteries ended up lined up, as opposed to the teeth of other dinosaurs, at the incredibly front of its mouth, positioned together the muzzle's gently curved periphery.

Nigersaurus is believed to have lived in big herds and may have migrated in excess of prolonged distances in search of food.

These teeth were being also replaceable (like sharks’ teeth), meaning Nigersaurus constantly required fresh new teeth as more mature ones were worn down or shed.

There have been debate on regardless of whether its head was habitually held downwards, or horizontally like other sauropods. It lived inside a riparian habitat, and its food plan likely consisted of soft crops, including ferns, horsetails, and angiosperms. It is One of the more prevalent fossil vertebrates discovered in the area, and shared its habitat with other dinosaurian megaherbivores, and also substantial theropods and crocodylomorphs.

Depending on this biomechanical Investigation, the staff concluded that the head and muzzle have been habitually oriented sixty seven° downwards and shut to floor amount, being an adaptation for floor-stage browsing. This is often unlike the way in which other sauropods have already been restored, with their heads held a lot more horizontally.[3]

Nigersaurus was named once the West African nation where by its fossils had been learned: the Republic of Niger. In the course of this creature’s time, the landscape (now A part of the Sahara Desert) is considered to happen to be included with forests and braided rivers.

Paleontologist Paul Sereno described Nigersaurus as “the weirdest dinosaur I’ve ever seen” once the dinosaur’s strange functions have been initial uncovered in 2007. The teeth had been particularly noteworthy simply because they ended up organized in dental batteries, which are generally present in beaked herbivores like Triceratops and Edmontosaurus, but are exceptional between sauropods.

He found out quite a few fossils from Elrhaz formations in Niger. Among the All those fossils, he identified fossils of a different dinosaur species that is called Nigersaurus (“Niger Reptile”). He along with other paleontologists collected quite a few bony areas of Nigersaurus individually and assembled a tough skeleton.

Greater still, People tooth columns were packed appropriate together with each other—like canned sardines. So a dinosaur armed with dental batteries could comfortably residence various hundred teeth (aged and new) within its mouth.

The restricted comprehension of the genus was the results of bad preservation of its continues to be, which arises with the delicate and highly pneumatic construction (filled with air spaces linked to air sacs) on the cranium and skeleton, subsequently leading to disarticulation of the fossils. Many of the cranium fossils had been so slender that a solid light-weight beam was visible as a result of them. Thus, no intact skulls or articulated skeletons happen to be found, Nigersaurus and these specimens characterize essentially the most full identified rebbachisaurid continues to be.[three][1]

Nigersaurus did not exhibit the identical modifications found from the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing capabilities. The reduced jaw was L-shaped and divided in to the subcylindrical transverse ramus, which contained the teeth, as well as back again ramus, which was much more light-weight and was The situation for most of the muscle mass attachments. It had been unique in the tooth row expanded to the perimeters within the plane of the principle ramus from the reduced jaw.

The authors therefore cautioned towards employing semicircular canals as proxy to infer the specific orientation of skulls. They found that diet plan correlated strongly with semicircular canal orientation, but not with head posture, although head posture and semicircular canal orientation ended up strongly correlated with phylogeny.[twenty five]
