Sooner or later, back again while in the lab, Sereno needed to request a next view from colleagues who labored on fossil fish and also other reptiles just before he figured it out.
Nigersaurus probable utilised its dental batteries to effectively procedure minimal-lying crops like ferns and horsetails, which it collected with its large muzzle. It possible fed at floor stage resulting from its brief neck, and its teeth would have worn out swiftly from shearing via tricky vegetation.
Preliminary discoveries of Nigersaurus fossils date back again to the sixties, nevertheless it was not until eventually the 1970s that additional full continues to be had been uncovered. These continues to be had been formally analyzed and explained by paleontologist Paul Sereno and his group in 1999.
Fossils of the dinosaur ended up to start with described in 1976, but it was only named Nigersaurus taqueti in 1999, soon after further and much more comprehensive continues to be ended up identified and explained. The genus identify usually means "Niger reptile", and the specific name honours the palaeontologist Philippe Taquet, who found the initial stays.

There have been discussion on regardless of whether its head was habitually held downwards, or horizontally like other sauropods. It lived inside a riparian habitat, and its diet program almost certainly consisted of sentimental vegetation, like ferns, horsetails, and angiosperms. It is one of the most popular fossil vertebrates observed in the area, and shared its habitat with other dinosaurian megaherbivores, along with large theropods and crocodylomorphs.
Dependant on this biomechanical analysis, the crew concluded that the head what dinosaur has 500 teeth and muzzle have been habitually oriented sixty seven° downwards and close to ground degree, as an adaptation for ground-stage searching. This is in contrast to the best way other sauropods are already restored, with their heads held additional horizontally.[three]
This aspect has captured community notice, which makes it The most memorable facets of Nigersaurus's biology, particularly in on the web discussions.
The teeth’s distinctive shape and arrangement ended up perfectly suited to its feeding practices. The slender, chisel-like teeth could successfully snip off smooth vegetation, as well as their rapid substitute ensured the dinosaur could consistently feed without looking forward to new teeth to improve.
Nigersaurus is believed to behave very similar to other herbivore sauropods. They'd most likely invested most of their time in dangle-Pet positions and grazing lower-lying vegetation.
Lifestyle restoration Nigersaurus was unique in that its dorsal (back) vertebrae had paired pneumatic Areas at the base on the neural spines (the spines that projected upwards from the vertebrae). The presacral vertebrae (vertebrae in front of the sacrum) have been heavily pneumatised to The purpose in which the column consisted of the series of hollow "shells", Every single divided by a skinny septum in the middle. It had minor to no cancellous bone, earning the centra skinny bone plates crammed with air spaces. The vertebral arches have been so closely pierced by extensions from the exterior air sacs that in their facet walls minor remained but two mm (0.
The Nigersaurus, with its staggering 500 teeth, offers a fascinating distinction to its dinosaur family, Specially other sauropods. As opposed to its cousins with fewer, thicker teeth, the Nigersaurus’s slender, pencil-like teeth were being uniquely adapted for snipping soft vegetation, a stark difference within the sturdy teeth of sauropods like Brachiosaurus, which ended up possible intended to handle more durable plants.
The lizard from Niger was a relatively smaller sauropod, measuring all-around 9 meters (30 feet) in duration and weighing about four tons. It experienced an extended neck and tail, with a short, narrow snout which was tailored for searching on minimal-lying vegetation.
Nigersaurus is believed to possess lived in substantial herds and might have migrated in excess of lengthy distances on the lookout for foods.
