Nigersaurus probably applied its dental batteries to effectively process low-lying crops like ferns and horsetails, which it collected with its vast muzzle. It most likely fed at ground amount on account of its brief neck, and its teeth would have worn out promptly from shearing via tough vegetation.
Nigersaurus was named and described in more depth by Sereno and colleagues only in 1999, based on stays of freshly discovered people. The identical report also named Jobaria, another sauropod from Niger. The genus title Nigersaurus ("Niger reptile") is actually a reference on the place wherever it had been uncovered, and the particular title taqueti honours Taquet, who was the very first to organise huge-scale palaeontological expeditions to Niger.
There have been discussion on no matter whether its head was habitually held downwards, or horizontally like other sauropods. It lived inside of a riparian habitat, and its eating plan almost certainly consisted of soft crops, for instance ferns, horsetails, and angiosperms. It truly is Probably the most common fossil vertebrates observed in the region, and shared its habitat with other dinosaurian megaherbivores, together with huge theropods and crocodylomorphs.
Because of this as a person tooth wore down or broke off, An additional was willing to just take its place. This fast tooth replacement cycle, happening around each and every fourteen times, ensured that Nigersaurus constantly had functional teeth to system its food.
Nigersaurus, a rebbachisaurid sauropod from the center Cretaceous interval, was found from the Elrhaz Development in Niger. Its identify, which means “Niger’s lizard,” was specified subsequent the invention of more full stays in 1999, Whilst its fossils had been very first explained in 1976.
Nigersaurus's feeding tactic was unlike a number of other dinosaurs. Its broad, flat jaw was adapted for grazing near to the bottom, earning it the nickname "Mesozoic Cow."
They consisted of vertically stacked columns of replaceable teeth. Every time the best tooth wore out in any given column, the a person ideal underneath it would go upwards and take the outdated tooth's place.
The quick alternative of its teeth, every 14 times, indicates the Nigersaurus confronted important evolutionary pressures to keep up a continuing provide of functional teeth to cope with abrasive plant product. This adaptation underlines the evolutionary imperative to improve feeding performance within an setting where by food items sources assorted and Levels of competition was intense.
The reconstructed skeleton of an extremely Strange dinosaur, the plant-feeding on Nigersaurus. That is a sculptural rendition of what the experts be expecting the dinosaur's distinct head could possibly have appeared like.
Life restoration Nigersaurus was distinct in that its dorsal (back) vertebrae had paired pneumatic spaces at The bottom on the neural spines (the spines that projected upwards from your vertebrae). The presacral vertebrae (vertebrae in front of the sacrum) were seriously pneumatised to The purpose wherever the column consisted of a number of hollow "shells", Each and every divided by a thin septum in the middle. It experienced small to no cancellous bone, creating the centra slender bone plates filled with air Areas. The vertebral arches had been so greatly pierced by extensions from the external air sacs that in their aspect walls small remained but two mm (0.
What dinosaur has five hundred teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert one hundred ten million years in the past. These sauropod dinosaurs collected foods that has a massive, broad mouth; the snout was broader in comparison to the back with the creature's head on the original fossil cranium.
The journey to uncover the tricks on the Nigersaurus commenced with the 1st fossil fragments learned during the nineteen seventies in the Elrhaz Development of Niger, however it wasn’t till 1999 that a lot more comprehensive stays introduced this fascinating dinosaur in to the spotlight. These discoveries presented paleontologists with the two issues and chances.
These teeth and The form in the sauropod's skull likely advanced to help it munch on crops low to the bottom. Grass wasn’t all over yet during its time, but Nigersaurus in all probability put in A lot of its time grazing on a thing 500 teeth dinosaur like it, sporting down its teeth right away.
