The Nigersaurus, also known as the “Niger lizard” or the “Niger reptile,” was a species of dinosaur that lived in the early Cretaceous period, between 121 million years ago and 99 million years ago.
More than 500 teeth and a purely herbivorous diet distinguished this unusual dinosaur from others. The herbivorous sauropod Nigersaurus belonged to the genus Sauropoda, which included other enormous herbivores. Brachiosaurus and diplodocus are two other notable sauropods.
In comparison to an African elephant, this sauropod was estimated to have been between 15 and 30 feet long and to have weighed between 4-5 tonnes.
A large number of postcranial bones have been found in Niger, Algeria, and Tunisia, where the dinosaur is said to have originated. In the Gadoufaoua region of central Niger, in the Elrhaz Formation, human remains have been found.
Fossils from the Nigersaurus are said to have been discovered in 1976, but it wasn’t until 1999 that the species was officially named. Nigersaurus taqueti, named for French palaeontologist Philippe Taquet, the first to discover the sauropod’s remains, is thought to be the only species in the genus.

Paul Sereno, a palaeontologist, dubbed the Nigersaurus the “mesozoic cow.” “The weirdest dinosaur I’ve ever seen,” Sereno was quoted as saying of this sauropod.
The Nigersaurus had more than 500 teeth as a distinguishing feature. In what is now the Sahara desert, this unusual herbivore is said to have grazed for food. It ate by snatching food out of the air with its long, snout-like snout. Paul Sereno, a palaeontologist, was also quoted as saying that the Nigersaurus’ face resembled that of a vacuum cleaner.
Reconstructed skeletons show that Sereno’s mouth closely resembles the end of a vacuum cleaner, proving that the vacuum cleaner comparison made by Sereno was correct.
With four large side fenestrae, or openings in the skull, along with thing bones, the wide muzzle proved to be a specialised tool for feeding. Over 500 teeth adorned its wide muzzle, with new ones growing in at a rate of one tooth every fourteen days.
When it came to the Nigersaurus’s jaw, teeth, and mouth, it was anything but conventional. It is the only known tetrapod with jaws wider than its skull in terms of jaw structure. Along with this, it is the only tetrapod that has been able to examine teeth that extend laterally across the front of the mouth.
For a sauropod dinosaur, this creature had an unusual tooth structure. The Nigersaurus, a sauropod that has never been seen before, has been found to have a unique feature: dental batteries. Triceratops and other beaked herbivores like it, like the triceratops, had dental batteries, but sauropods did not.
Herbivores used dental batteries because of their high processing efficiency. As long as a tooth wore out in a column, it would be replaced by the one behind it, which would take the old tooth’s place, according to legend. Like a pod of peas, the tooth columns would be tightly packed together. There are many ways in which a dinosaur’s mouth could hold hundreds of teeth, both old and new.
The upper jaw of the Nigersaurus contained about 60 columns of small, needle-like teeth. The lower jaw, on the other hand, had about 68 columns. There were nine sets of replacement teeth in the nigersaurus’s jaw when all of the columns were taken into consideration.
Nigersaurus’ teeth are also unique because of their orientation. There’s no point in having teeth that extend laterally in order to chomp down on the leaves that are hanging from the trees. Nigersaurus feeding and grazing on the ground is supported by evidence. That’s how “mesozoic cow” got its start. Feeding amongst the low-lying plants, the wide muzzle would be an ideal companion. The dinosaur would have been able to eat its way through the vegetation thanks to its many teeth. For the Nigersaurus, the dental batteries would have been essential because each new tooth was said to have been replaced every fourteen days.
As a member of the sauropod family, the Nigersaurus was the largest known dinosaur. According to other sauropods, the Nigersaurus was a much smaller creature. Diplodocus measured an average of 85 feet long, whereas the Nigersaurus was estimated to be around 30 feet long. Diplodocus, on the other hand, was said to have weighed as much as a modern African elephant (around 4-5 tonnes). Because of this, we can classify the Nigersaurus as a medium-sized dinosaur. The Nigersaurus also had a shorter neck than other members of its family, making it a smaller relative.
Nigersaurus Facts – Our Top Five Picks
1. Nigersaurus is described as a short-necked ‘long neck’ dinosaur
Long necks are the primary distinguishing feature of the sauropod family. This is six times longer than the world’s longest giraffe neck, which is 15 metres in length. For the Nigersaurus and its closest relatives (the Rebbachisauridae), however, this is not the case. Rebbachisaurids had necks of less than 10 metres in length in the vast majority of cases.
2. The ‘Niger Lizard’
The Nigersaurus is known as a ‘Niger lizard’ or a ‘Niger reptile’ in English translation. Due mainly to the discovery of its remains in what is now Niger.
3. The discovery of Nigersaurus babies
Nigersaurus fossils were discovered by palaeontologist Paul Sereno during an expedition. A baby Nigersaurus’ upper jaw was described as “fitting on top of a silver dollar,” despite the fact that fully grown adults could reach 30 feet in length.
4. Plants only
The sauropod family includes the Nigersaurus. Sauropods were any of the Sauropod dinosaurs. Size, neck and tail, four-legged stance and herbivorous diet were some of their most distinguishing characteristics (plant eaters.)
5. The posture debate
Whether or not the Nigersaurus slouched or stood tall has been debated by scientists. When these creatures were first discovered, some scientists thought they might be able to keep their skulls at a constant 67-degree angle, making it easier for them to find food. It has been claimed that the vertebrae of dinosaurs allowed for a much greater range of motion than previously thought. So, the Nigersaurus would have behaved more like other sauropods, with their necks tucked in.
What dinosaur has the most teeth?
In spite of its impressive tooth count, Nigersaurus falls short of setting a new record. 1,400 teeth were rumoured to have been in the mouths of Hadrosaurs. Among living creatures, their teeth were said to be the most complex of all time.
There you have it, a 500-tooth dinosaur. It’s the Nigersaurus. Even though it doesn’t have the most impressive skeleton of any dinosaur, this strange and unusual sauropod is sure to get people’s attention. With so many teeth at their disposal, what else can you expect?
