What dinosaur has 500.teeth

The Nigersaurus (pronounced “nee-zhayr-sore-rus”) was a dinosaur that lived between 121 and 99 million years ago, and whose name means “Niger lizard” or “Niger reptile.”

This one-of-a-kind dinosaur was notable for having over 500 teeth and eating only plants. Nigersaurus was a genus of sauropods, which were enormous herbivores that traveled largely on four legs and ate plants. The brachiosaurus and the diplodocus are two other noteworthy sauropods.

This sauropod was 15 meters (30 feet) long and weighed about 4-5 tonnes, whereas an African elephant weighs roughly 4 tonnes.

The dinosaur’s origins are thought to be in what is now known as central northern Africa, with postcranial bones discovered in Niger, Algeria, and Tunisia. The Elrhaz Formation, in the Gadoufaoua region of central Niger, has notably yielded remains.

The first Nigersaurus fossils were discovered in 1976, but it wasn’t identified until 1999 after more extensive and complete remains were discovered. Nigersaurus taqueria, named after French paleontologist Philippe Taquet, who was the first to uncover the sauropod’s remains, is thought to be the only species in the genus.

Characteristics that Set It Apart

Paleontologist Paul Sereno dubbed the Nigersaurus the “Mesozoic Cow.” Sereno was quoted as saying that this unique sauropod was “the craziest dinosaur I’ve ever seen.”

Teeth of a Nigersaurus


The Nigersaurus’ 500+ teeth were one of its most distinguishing features. This unusual herbivore was supposed to have grazed for sustenance in the Sahara desert, which is now largely desert. With its enormous, broad mouth and a snout that was wider than the back of its skull, it gathered food. Paleontologist Paul Sereno was also quoted comparing the Nigersaurus’s visage to that of a vacuum cleaner.

Sereno’s vacuum cleaner comparison has been confirmed, with reconstructed skeletons showing its mouth to be remarkably similar to that of the domestic appliance’s end.

With four huge side fenestrae, apertures in the skull coupled with thing bones, the wide snout proved to be a specialized tool for feeding. It had about 500 teeth in its wide muzzle, which were reported to be replaced every 14 days.

The Nigersaurus’ jaw, teeth, and mouth structure were unusual, to say the least. It is the only known tetrapod animal with jaws that are wider than its skull in terms of jaw anatomy. In addition, it is the only tetrapod with teeth that extend beyond the jaw.

This unusual dinosaur had an unusual tooth structure, notably for a sauropod dinosaur. Another remarkable feature of the Nigersaurus was the discovery of dental batteries, which had never been seen before in a sauropod family. Dental batteries have been seen in triceratops and other beaked herbivores, but they are extremely rare in sauropods.

For those who ate a herbivorous diet, dental batteries were known as highly efficient processing equipment. They were supposed to be made up of vertically stacked columns of interchangeable teeth, with each tooth in each column being replaced by the one behind it, which would take the old tooth’s place.

The upper jaw of the Nigersaurus featured around 60 columns of tiny, needle-like teeth. The lower jaw, on the other hand, had about 68 columns. With the entire set of columns taken into account, the nigersaurus had almost 500 individual teeth, equating to nine sets of replacement teeth stored within the jaw.

The direction of the Nigersaurus’ teeth contributes to their peculiarity. When munching on the leaves dangling from the branches, having teeth that extended laterally at the front of its mouth wouldn’t have been very useful. As a result, evidence suggests that the Nigersaurus ate and grazed on the ground. As a result, the term “Mesozoic cow” was coined.

The wide muzzle would be an ideal companion for foraging among the low-lying vegetation. The dinosaur would have had no trouble plowing through the foliage thanks to its abundance of teeth. Each new tooth was claimed to be changed every 14 days, therefore the dental batteries would have been crucial for the Nigersaurus when feeding along the floor bed.

Nigersaurus Dimensions


The sauropod family included the Nigersaurus, which was one of the largest dinosaurs ever to walk the world. When compared to other sauropods like the Brachiosaurus or Diplodocus, the Nigersaurus was significantly smaller. In comparison, the Nigersaurus was thought to be around 30 feet long, while a Diplodocus was predicted to be around 85 feet long. The weight of these little giants is claimed to be comparable to that of a current African elephant (about 4-5 tonnes), whereas a diplodocus weighed around 25 tonnes. As a result, the Nigersaurus can be considered a little giant in the broad scheme of things. The Nigersaurus, in addition to having a smaller frame, also had a smaller head.

Facts about the Nigersaurus – Our Top Five Picks


  1. Nigersaurus is a ‘long neck’ dinosaur with a short neck.

The sauropod family’s most distinguishing feature is undoubtedly their long necks. Some sauropod necks measured 15 meters in length, six times greater than the world’s largest giraffe neck. The same cannot be true for the Nigersaurus and its closest cousins (the Rebbachisauridae). The Rebbachisaurids’ necks were all less than 10 meters long.

  1. The ‘Niger Lizard’

The name Nigersaurus refers to a “Niger lizard” or “Niger reptile.” Mostly because its relics were uncovered in what is now the Republic of Niger.

  1. The finding of baby Nigersaurus

Paleontologist Paul Sereno discovered fossils of a newborn Nigersaurus while on an expedition in Niger. Despite fully grown adults reaching 30 feet in length, the upper jaw of a baby Nigersaurus was found to “fit on top of a silver dollar.”

  1. Only plants

The sauropod family includes the Nigersaurus. Sauropods were dinosaurs belonging to the Sauropoda subgroup. Their massive stature, long neck and tail, four-legged stance, and herbivorous diet were their most distinguishing features (plant-eaters.)

  1. The issue of posture

Scientists have hypothesized whether the Nigersaurus would slouch or hold its head up on a regular basis. Initially, scientists hypothesized that these complex creatures’ skulls would be permanently lowered at a 67-degree angle, making food-seeking easier. However, experts have recently refuted this assumption, claiming that the vertebrae of dinosaurs allowed for a far broader range of motion.

Who has the most teeth among the dinosaurs?

Despite its high tooth count, the Nigersaurus does not hold the record for most teeth. Hadrosaurs were known to have up to 1,400 teeth. Their teeth were considered to be the most intricate of any living creature.

So now you know, what dinosaur has 500 teeth. The Nigersaurus is a dinosaur that lived in Africa. This strange and amazing sauropod may not have the most dinosaurs, but it certainly has people talking. With all those teeth at their disposal, what do you expect?

The three-dimensional models of this dinosaur may be seen above. By the way, I’d want to share some information with you. Three-dimensional modeling technology advanced significantly in the 2000s, as you may be aware. Scientists have developed a method for creating 3D reconstructions of dinosaurs using skeletons.

Dinosaur research has become more popular as a result of technological advancements. Professional eyes can easily understand what the animal looks like, but such 3d models are more useful for common people like us.

I would never have guessed 500 teeth fit into the Nigersaurus’ mouth if I hadn’t seen the 3D model. The mouth of this dinosaur is straight. The upper and bottom portions of the flat mouth have tiny teeth that resemble cat teeth. Of course, it isn’t as little as a cat’s. Only in terms of proportion, the dinosaur has few teeth in comparison to its body.

These teeth make it easier for him to consume the grass in the trees. Nigersaurus has a small head and a lengthy body because it is a herbivorous dinosaur. Its head is small in comparison to the rest of its body. It can easily reach high branches because of its long and active neck.

This dinosaur’s bones have been discovered in the Niger region of West Africa. The Nigersaurus now lives in the desert, which is an interesting fact. It was, nevertheless, a green location with spring waters during the dinosaur era. It was home to not only dinosaurs but also various fish and other species. The fossils of a herbivorous dinosaur discovered in the middle of the desert also demonstrate the Earth’s climate’s variability.

During his lifetime, this lone skeleton interacted with a variety of animal species. Many of these animal species have vanished. When an animal dies, the world becomes a lonely place.

Although Nigersaurus has the most teeth, it is not the largest dinosaur. The titanosaurian sauropods were the largest herbivorous dinosaurs in the area at the time.

The Jurassic Park film introduced our generation to dinosaurs. To be honest, I had no idea dinosaurs existed before seeing this film.

Maybe that’s why the movie had a stronger impact on me than it did on others. When I read the book Sapiens, which allowed me to learn about the existence of other human species, I had a similar reaction. We are homo-sapiens or members of the human species. Outside of us, though, there were a variety of people. There were larger and smaller ones among them, as well as stronger ones.

The Lord of the Rings movie’s dwarves and elves could be genuine. The earth existed millions of years ago; when we view these stories now, they look amazing. The planet is older than we previously believed. There was human history before human history.
