The remains of Nigersaurus were being initially described by Taquet in 1976 as belonging to a dicraeosaurid, but in 1999 Sereno and colleagues reclassified it as being a rebbachisaurid diplodocoid.[4] These scientists speculated that due to the fact short necks and small measurement was acknowledged among the basal diplodocoids, it may well suggest these were ancestral functions from the group.
Nigersaurus possible employed its dental batteries to effectively process minimal-lying plants like ferns and horsetails, which it collected with its large muzzle. It very likely fed at ground stage as a consequence of its small neck, and its teeth would've worn out swiftly from shearing through challenging vegetation.
Fossils of this dinosaur were being 1st explained in 1976, but it was only named Nigersaurus taqueti in 1999, just after even further and even more finish remains were being identified and explained. The genus name signifies "Niger reptile", and the specific title honours the palaeontologist Philippe Taquet, who found the primary continues to be.
A 2009 analyze via the British palaeontologist Mike P. Taylor and colleagues agreed that Nigersaurus was in a position to feed Along with the downturned head and neck posture proposed because of the 2007 examine, but contested that this was the habitual posture from the animal. The analyze pointed out the "neutral" head and neck posture of contemporary animals will not always correspond to their habitual head posture.
Although other major animals examined (for example rhinoceroses) experienced thick and variable bone cortices, the cortex of Nigersaurus was somewhat skinny. These scientists advised which the microanatomy of sauropods was not afflicted by drastic selective force due to bearing excess weight, but that attributes including the columnar limbs (as found in elephants), pneumaticity, and fleshy foot pads and cartilage peaceful force about the bones. Additionally they recommended that sauropods could as a result happen to be lighter in weight than expected for his or her dimensions, supporting the bottom entire body mass estimates for these dinosaurs.[22]
Daily life restoration Nigersaurus was unique in that its dorsal (back again) vertebrae experienced paired pneumatic spaces at the base in the neural spines (the spines that projected upwards in the vertebrae). The presacral vertebrae (vertebrae before the sacrum) had been closely pneumatised to The purpose exactly where the column consisted of the number of hollow "shells", Every single divided by a thin septum in the middle. It experienced minor to no cancellous bone, creating the centra slender bone plates stuffed with air spaces. The vertebral arches were so heavily pierced by extensions of your exterior air sacs that of their facet partitions tiny remained but 2 mm (0.
The human brain is Probably the most amazing organs within our body. It controls every little thing we do—pondering, emotion, going, and even
Nigersaurus is known to obtain lived in what is now modern-day-day Niger, Africa, that's why its title. It absolutely was to start with identified from the early 2000s by a team of paleontologists led what dinosaur has 500 teeth by Paul Sereno.
Nigersaurus's downward-experiencing mouth and extensive dental arrangement recommend it grazed on ground-level vegetation in lieu of searching significant vegetation.
The genus Nigersaurus was formally named in 1999 by American paleontologist Paul Sereno and his group, next the discovery of more finish remains that authorized for a detailed description with the species.
Among the most distinctive functions of Nigersaurus was its rows of little, peg-like teeth, which were being organized inside a straight line alongside the entrance of its jaws. These teeth ended up repeatedly changed throughout the dinosaur’s lifestyle, making it possible for it to feed frequently on challenging vegetation.
What dinosaur has five hundred teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert 110 million years ago. These sauropod dinosaurs gathered food stuff using a major, wide mouth; the snout was wider when compared to the back again in the creature's head on the initial fossil skull.
With an astonishing 500 teeth, this dinosaur presents a unique glimpse into your evolutionary adaptations of prehistoric creatures. Permit’s explore the planet with the Nigersaurus and its fascinating dental anatomy.
Diplodocus cranium for comparison Its skull was really various from Diplodocus, suggesting another feeding strategy. It had quite a few fenestrae (openings) and slender bones. It had a large muzzle filled with much more than 500 teeth.
