“It’s something which really can take the cake for incredible cranial adaptations In this particular team, the extensive-necked dinosaurs,” suggests Sereno, a professor of paleontology at the University of Chicago. “It’s just a majestic example of evolution.”
While going for walks across an incredibly flat place, Gabe built a remarkable come across—the bones of a whole new meat-taking in dinosaur lay partially exposed at her toes. She brushed away the sand within the higher jaw.
This Nigersaurus was a hatchling, most likely lower than one particular yr from hatching when it died and was fossilized.”
“This is actually the first sauropod that has a tooth battery,” Sereno says, adding that its jaw would've been angled downwards instead of forwards — Which explains why Sereno experienced this kind of issues fitting the bones alongside one another originally.
The Nigersaurus experienced exceptionally extended neck. It had been about twice the length of its entire body. This adaptation is thought to own evolved in order to enable Nigersaurus to achieve greater levels of vegetation. Nigersaurus also had a very tiny head. It calculated only about thirty centimetres (twelve inches) in width.
The analyze of dinosaurs like Nigersaurus will help us to raised understand the history of our World and the essential position that these historic creatures performed in shaping the globe as we comprehend it right now.
As we’ve witnessed, Nigersaurus experienced a large muzzle and diverse teeth beautifully suited for consuming lower-lying crops. This food plan and lifestyle would have demanded the creature to possess a constant supply of substitution teeth, mainly because it might have worn out its tooth crowns swiftly.

Its cranium was pretty specialised for feeding. It experienced 4 massive aspect fenestrae, openings while in the skull and skinny bones. It experienced a broad muzzle stuffed with in excess of five hundred teeth, which ended up replaced about every single 14 days. The jaws can have had what dinosaur has 500 teeth a keratinous sheath, some thing like a wide beak. Nigersaurus is the only recognised tetrapod animal to obtain experienced jaws wider compared to skull and teeth that prolonged laterally through the entrance.
Paleontologist Paul Sereno explained Nigersaurus as “the weirdest dinosaur I’ve at any time viewed” if the dinosaur’s uncommon capabilities had been 1st learned in 2007. The teeth ended up specifically noteworthy given that they were arranged in dental batteries, which are usually present in beaked herbivores like Triceratops and Edmontosaurus, but are scarce among sauropods.
Fossils of this dinosaur have been initially explained in 1976, but it absolutely was only named Nigersaurus taqueti in 1999, after additional and even more total remains were discovered and described. The genus name implies "Niger reptile", and the particular title honours the palaeontologist Philippe Taquet, who found the initial stays.
Nigersaurus experienced issue in holding their head upward or horizontally. So taking in leaves and other areas of very long Trees was impossible for them.
Though other significant animals examined (including rhinoceroses) had thick and variable bone cortices, the cortex of Nigersaurus was somewhat slender. These researchers advised that the microanatomy of sauropods was not impacted by drastic selective tension due to bearing excess weight, but that features such as the columnar limbs (as witnessed in elephants), pneumaticity, and fleshy foot pads and cartilage calm stress on the bones. They also proposed that sauropods could for that reason are actually lighter in body weight than anticipated for his or her measurement, supporting the bottom physique mass estimates for these dinosaurs.[22]
These teeth had been specialized for efficiently cropping and grinding tender, small-lying vegetation. The dinosaur’s teeth ended up continuously replaced, with new ones escalating just about every fourteen days to maintain functionality.
