Reconstructed skeleton of Nigersaurus, showcasing the dinosaur's distinctive five hundred-tooth jaw composition and elongated human body.
Fossils of this dinosaur were being initially explained in 1976, but it was only named Nigersaurus taqueti in 1999, following further and even more entire remains ended up discovered and explained. The genus title usually means "Niger reptile", and the particular identify honours the palaeontologist Philippe Taquet, who discovered the main remains.
Its cranium was really specialised for feeding. It had four significant aspect fenestrae, openings within the cranium and slim bones. It had a wide muzzle stuffed with a lot more than five hundred teeth, which had been changed all around each and every 14 times. The jaws could have had a keratinous sheath, anything similar to a vast beak. Nigersaurus is the only known tetrapod animal to own experienced jaws wider than the cranium and teeth that extended laterally through the front.
We thoroughly brushed the sand off the a hundred and ten million-yr-aged bones and dug channels amongst the major regions of the skeleton. Before long We'll address Every single area in plaster so that the skeleton might be transported out of the sector and again to the laboratory.
Everyday living restoration Nigersaurus was unique in that its dorsal (back again) vertebrae experienced paired pneumatic spaces at the base from the neural spines (the spines that projected upwards in the vertebrae). The presacral vertebrae (vertebrae before the sacrum) ended up heavily pneumatised to the point exactly where the column consisted of a number of hollow "shells", Each individual divided by a skinny septum in the middle. It had minimal to no cancellous bone, building the centra skinny bone plates filled with air Areas. The vertebral arches ended up so seriously pierced by extensions from the exterior air sacs that of their facet partitions tiny remained but 2 mm (0.
Nigersaurus had over 500 teeth arranged in dental batteries (rows of teeth stacked upon other rows of teeth), which permitted it to proficiently graze on minimal-lying vegetation like ferns and horsetails. Worn teeth had been continuously replaced to keep up Niversaurus' successful feeding.
These teeth ended up also replaceable (like sharks’ teeth), meaning Nigersaurus continuously expected new teeth as older types had been worn down or misplaced.
Although going for walks across a really flat area, Gabe manufactured a impressive find—the bones of a new meat-eating dinosaur lay partially uncovered at her feet. She brushed away the sand through the higher jaw.
The cranium of the Nigersaurus was made from slim bones and experienced a lot of little openings and pores. These features furnished them great versatility in feeding on the ground. The muzzle with the Nigersaurus was wide and lengthy which assisted Nigersaurus it in consuming modest floor-centered vegetation.
Everyday living restoration Nigersaurus was distinct in that its dorsal (back again) vertebrae experienced paired pneumatic spaces at the base with the neural spines (the spines that projected upwards from your vertebrae). The presacral vertebrae (vertebrae before the sacrum) were closely pneumatised to the point the place the column consisted of the number of hollow "shells", Each and every divided by a thin septum in the center. It had tiny to no cancellous bone, building the centra slender bone plates filled with air spaces. The vertebral arches ended up so closely pierced by extensions from the external air sacs that in their side partitions minimal remained but 2 mm (0.
What dinosaur has five hundred teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert 110 million yrs ago. These sauropod dinosaurs collected foods with a massive, broad mouth; the snout was broader as opposed to again from the creature's head on the original fossil cranium.
The sauropod dinosaur Nigersaurus likely progressed its surprisingly-shaped head to raised mow prehistoric lawns.
eight ft) in size and weighing about 2 tons. Irrespective of its tiny sizing as compared to other sauropods, it obtained attention resulting from its special anatomy, including a broad muzzle resembling a vacuum cleaner and dental batteries consisting of numerous compact, needle-shaped teeth arranged in columns.
