Dinosaur Has 500 Teeth

What Dinosaur has 500 teeth? This question is being asked worldwide. The question was also asked on Reddit where someone cracked a racist joke about it and it went viral.

What Dinosaur has 500 teeth?

Short answer: Nigersaurus was one of the many species of Dinosaurs. This species is considered to have about 500 teeth.  

It was located in the Elrhaz Formation of Niger, specifically in the Gadoufaua region of the country. During the Cretaceous era, approximately 115 to 105 million years ago, a species of rebbachisaurid sauropod dinosaur known as Nigersaurus roamed the earth. The territory that is today the Sahara Desert would have been home to lush marshes when the 30-foot herbivore was roaming the earth. It possessed a broad mouth lined with five hundred thin teeth that were specifically specialized for browsing plants that were low to the ground. It also had a delicate and distinctive cranium. 

How did Nigersaurus earn its name?

The sands of the Saharan Desert were the cradle of a novel and peculiar dinosaur species. A beast the size of an elephant that had a skull and jaws, yet it was unlike anything that experts had ever seen before. That particular dinosaur would later become known as Nigersaurus. Because many Paleontologists believe that their behavior was comparable to that of current cows, it has been given the nickname “Mesozoic Cow.” Nigersaurus was one of the oldest sauropod morph herbivore dinosaurs ever found. It’s a Diplodocus-like sauropod dinosaur genus. 

When did Nigersaurus live?

During the period known as the Cretaceous, the Nigersaurus dinosaur was active over the landmasses of Africa. It is known to have existed between the Aptian Age and a long time ago, and its remains have been found in nations such as Niger, which is located in Africa. This period includes the Aptian and Albian phases, as well as the Cenomanian period. The grasslands and forests of Africa were the ancestral habitats of the dinosaur. The riparian zone was a common habitat for Nigersaurus, which was typically found in areas that were near bodies of water like lakes or streams. Because of the prevalence of water in the area, riparian zones are characterized by an abundance of plant that grows at a lower elevation. The only species of sauropod known to have grazed was Nigersaurus, and many specialists believe that this behavior may have been nearly constant.

What did Nigersaurus eat?

Its mouth, which was shaped like a shovel and featured more than 500 teeth, made it ideally suited for consuming vast quantities of vegetation as it moved along. It is hypothesized that the head of the Nigersaurus would have spent almost all of its time on the ground and that it would have consumed the equivalent of one football field’s worth of plants in a single day. Numerous Paleontologists s believe that the arrangement of the Nigersaurus 500’s teeth served a purpose similar to that of a comb. However, given the fragility of its jawbones, other experts assume that it simply used its teeth to chop vegetation and then sucked it in using a motion similar to a vacuum. Unfortunately, when the environment changed, different types of vegetation began to replace the specialist grasses to which it had grown specifically adapted to survive. Nigersaurus was unable to successfully adapt to its environment, and as a result, it became extinct.

Where exactly was the Nigersaurus fossil found?

Nigersaurus was found in the Elrhaz Formation near Gadoufaua, which is located in the Republic of Niger. This formation is known for its abundant fossil vertebrate fauna. Philippe Taquet, a French Paleontologist who was on an expedition to Niger between 1965 and 1972 and discovered the first bones of the Nigersaurus taqueti species, is honored with the naming of the sole species in the genus, which bears his name. Even though Nigersaurus fossils were found and reported in 1976, the name “Nigersaurus” wasn’t given to the dinosaur until 1999, when more complete remains were found and published. In the world of dinosaurs, Nigersaurus belonged to which family? The Sauropodomorpha suborder, the Diplodocoidea superfamily, the Rebbachisauridae family, and the Nigersaurinae subfamily are the dinosaur groups to which the Nigersaurus belonged. Other dinosaur groups to which it belonged include:

When it was first discovered, the structure of Nigersaurus was assumed to be comparable to that of members of the Dicraeosauridae family of dinosaurs because its structure appeared to be similar to that of members of this particular dinosaur family. But in light of recently unearthed fossil data, Paul Sereno reclassified the bones as belonging to a different species. The rebbachisaurid dinosaurs are the most basic members of the superfamily Diplodocoidea since they do not possess the bifid neural spines that are present in the other dinosaur species. It’s interesting to note that nigersaurinianians have hollow bones that are filled with air.

Where exactly can I view a Nigersaurus specimen?

The remains of the Nigersaurus, which date back 110 million years and are on display in the Explorers Hall of the National Geographic Museum in Washington, as well as in Japan, are accessible to anybody interested in seeing the legendary dinosaur that had 500 teeth. The skull, which includes all 500 teeth, is part of the skeleton that is currently on display.

What did Nigersaurus look like?

It took several years for experts to recognize the unusual characteristics of this Nigersaurus specimen. It wasn’t until the late 2000s that Paleontologists got a reasonably accurate picture of the appearance of the dinosaur known as Nigersaurus, even though it had been given its scientific name in 1976.

This is because the skeleton of this dinosaur is hollow in several locations, which makes it susceptible to breaking and distorting. Although there were a large number of specimens available before 1997, no considerable remains of Nigersaurus had been found at the time. This led many people to conclude that Nigersaurus was simply an average sauropod.

Mouths that are shaped like duck bills

Even wider than the snouts of the hadrosaurs that had “duck-billed” snouts, this one was. The teeth of these sauropods are one of the most important pieces of evidence for figuring out how they consumed food and what they consumed. The tiny facets and abrasions on the teeth display a pattern of micro scratches and pits that reflect what the Nigersaurus consumed for its diet. This, in turn, naturally wore down the teeth, and it enabled scientists to gather information to make an informed choice based on the diet of Nigersaurus, which comprised of soft vegetation.

Nigersaurus skull

The researchers noticed something peculiar about the animal’s skull when they analyzed it with computed tomography (CT). The scans revealed that Nigersaurus had “organs of equilibrium,” which are functionally analogous to the semicircular canals that are present in each of our ears and contribute to our capacity to keep our balance. According to the configuration of those organs, it would suggest that Nigersaurus spent most of its time with its head practically pointing straight down towards the earth. You could be thinking something like, “That’s not how these giant dinosaurs with long necks are typically portrayed, is it?” And you’d be correct! This lends credence to the idea that Nigersaurus was a ground-level grazer; if this were the case, the animal would have made use of its five hundred teeth in a manner analogous to that of a lawn mower, bringing in practically continuous amounts of grass. An investigation of the brain cavity revealed that the olfactory lobes of the Nigersaurus were noticeably underdeveloped, which leads paleontologists s to assume that despite having big nostrils, the Nigersaurus did not have a very developed sense of smell.

Nigersaurus had incredibly distinctive cranial characteristics

The skull of the Nigersaurus was one of the most peculiar ever found. Only one other tetrapod, the Nigersaurus, has jaws that are significantly wider than the rest of its skull. Its bones were incredibly weak, and in comparison to other sauropods, it possessed four additional fenestrae, which are openings in the skull that are located in front of the eye sockets. It is most likely that the tips of the jaws were covered with a keratinous substance. In addition, the mandible was curved like an S, and the nasal openings were made larger. Despite its delicate appearance, the skull bine had durability that allowed it to withstand the constant abrasion and wear that comes with consuming plants. Nigersaurus was given the moniker “Mesozoic cow” due to the distinctive features of its skull and the diet that it followed during its time on Earth.

One of the distinctive characteristics of the skull that Nigersaurus possessed was that there were just 1.0 cm2 of bone connecting the back of the head to the muzzle (0.16 sq. in). In several cases, the thickness of these bone connecting struts was less than 2 millimeters (0.08 inches).

Another characteristic that set Sauropodomorpha apart from other dinosaurs was the presence of a closed supratemporal fenestra. Although the precise position of the nasal bones has not been determined, the front margin of the bony nostril appears to be closer to the snout in this dinosaur than it is in other diplodocoids.

How big was Nigersaurus?

As was the case with the vast majority of sauropods, Nigersaurus was a quadrupedal dinosaur with a small skull, thick hind legs, and a prominent tail.

The body length of the Nigersaurus was about 9m-10m (30ft) and its femur was just 1m in length, making it one of the smallest members of that group (3ft 3 in). The weight of the Nigersaurus was approximately 4 tons (4.4 short tons), which is comparable to the weight of an elephant living today. In comparison to other sauropods, it had a relatively short neck with only thirteen cervical vertebrae. Its skull possessed several cranial bones that were extraordinarily thin, to the point that they were almost see-through. Nigersaurus had an unusual mouth for a sauropod, especially considering its size. After taking food into its mouth by its huge intake, which was wider than the rest of its skull, Nigersaurus would have used its 500 teeth to grind up the food it had consumed. According to Paleontologists, a hatchling Nigersaurus’ jawbone was so little that it could “fit on top of a silver dollar.” This is even though adult Nigersaurus could grow to lengths of up to 30 feet.

Nigersaurus fossilized remnants

The scientific community has experienced some irritation as a result of the remnants of the Nigersaurus since the bones were relatively thin and pneumatic. To such an extent that one of the Nigersaurus skull fragments that were discovered was so delicate that light could seep right through it. The bones were in a fragile condition, which contributed to their lack of preservation for any length of time. The good news is that nearly all of the Nigersaurus’ bones have been found, except for a few rib bones and coccygeal vertebrae. In 2005, a comprehensive essay on the appearance of Nigersaurus was released. The author of that essay discussed its distinctive skull, which had a total of five hundred teeth, in addition to its various adaptations for eating. In 2007, a paper that was more detailed and covered the full skeleton of Nigersaurus was published. A significant number of fossils discovered by other paleontologists s are currently undergoing analysis, and as the investigation moves forward, additional details will become accessible. Its name might be pronounced “nee-zhayr-sore-rus.” This one-of-a-kind dinosaur was distinguished by possessing more than 500 teeth and subsisting only on a plant-based diet. Nigersaurus was a genus of sauropods, which were extremely huge herbivores who traveled mostly on all fours. It was known for eating plants. The brachiosaurus and the diplodocus are two other well-known examples of sauropods. This particular sauropod measured 15 meters (about 30 feet) in length and was estimated to have weighed between 4 and 5 tons. For context, an African elephant weighs about 4 tons on average. It is believed that dinosaurs originated in what is now known as central and northern Africa. Remains have been found, most notably, within the Elrhaz Formation, which is located in the region of Gadoufaoua in central Niger. According to some accounts, the first Nigersaurus fossils were discovered in 1976; nevertheless, the genus wasn’t given its name until 1999, after more extensive and comprehensive discoveries of the dinosaur’s remains. It is believed that there are just one species in this genus, and that species is called Nigersaurus taqueti. 

Distinguishing Features and Attributes

A Paleontologist by the name of Paul Sereno gave the Nigersaurus the moniker of the “Mesozoic cow.” A notable comment attributed to Sereno discusses this peculiar sauropod, in which he refers to it as “the craziest dinosaur I’ve ever seen.”

Nigersaurus Teeth

The Nigersaurus had more than 500 teeth, which was one of its defining traits. It is believed that this peculiar herbivore once foraged for food in a region that is now dominated by the Sahara desert. It used its enormous, broad mouth to gather food; in fact, the width of its snout was more than the width of the back of its head. Paul Sereno, a Paleontologist, was also famously described as making the comparison that the face of the Nigersaurus resembled that of a vacuum cleaner. The analogy that Sereno made between himself and a vacuum cleaner has been deemed to be an accurate observation, with reconstructed bones demonstrating that the mouth of Sereno’s creature bore a striking likeness to the tip of the domestic device. The wide muzzle served as a specialized instrument for feeding, and it was equipped with four enormous side fenestrae, which are apertures in the skull that are accompanied by tiny bones. It was claimed to have more than 500 teeth, each of which was replaced once every two weeks, and it had a large nose. The jaw, teeth, and overall form of the mouth of the Nigersaurus were, at best, unconventional. In terms of the structure of its jaws, it is the only known tetrapod animal to have possessed jaws that were broader than its skull. This fact distinguishes it from all other known tetrapod animals. In addition to this, it is the only known example of a tetrapod that possessed teeth that extended laterally across the front of its mouth. This unconventional beast had a tooth structure that was significantly different from anything else seen in sauropod dinosaurs, in particular. It was discovered that the Nigersaurus has dental batteries, which is something that has never been observed previously in a sauropod family. This is another one of its distinctive characteristics. Dental batteries are widespread among beaked herbivores like the triceratops, but they have remained extremely uncommon among sauropods. Herbivores were known to benefit greatly from the use of dental batteries because they were among the most effective processing equipment available. It was stated that they consisted of columns of replaceable teeth that were stacked vertically atop one another. If one of the teeth in any given column became damaged or lost, the succeeding tooth in the column would step in and take its place. In addition to this, the teeth columns would be arranged in an orderly fashion adjacent to one another, much like beans in a pod. Therefore, dinosaurs who possessed dental batteries might very well have had hundreds of teeth, both old and new, in their mouths at the same time. In the case of the Nigersaurus, the upper jaw was packed with around 60 columns of incredibly minute teeth that resembled needles. While the lower jaw held around 68 columns in total. When the entire row of columns is taken into consideration, the Nigersaurus possessed more than 500 individual teeth, which translates to 9 sets of replacement teeth that are always ready to be used within the jaw. Another aspect that contributes to the singularity of the Nigersaurus’ teeth is their orientation. When it came to chewing on the leaves that were dangling between the trees, having teeth that extended laterally at the front of its mouth would not have been a particularly advantageous trait to possess. As a result, the data suggests that the Nigersaurus fed and grazed at ground level. Because of this, it got the moniker “Mesozoic cow.” The wide muzzle would prove to be an ideal companion for eating amid the low-lying plants, which is exactly what it was designed for. Because it possessed so many teeth, the dinosaur probably had no trouble tearing through the vegetation it encountered. Because each new tooth was claimed to have been replaced every 14 days by the Nigersaurus, the dental batteries would have been an absolute necessity for the animal as it was grazing along the floor bed.

Nigersaurus Size

The sauropod family included some of the largest dinosaurs that ever roamed the world, including the Nigersaurus, which belonged to this family. The Nigersaurus was a considerably more diminutive sauropod than other sauropods, such as the Brachiosaurus and the Diplodocus, for example. As a point of comparison, the length of a Nigersaurus was thought to be somewhere in the neighborhood of 30 feet, whereas the typical length of a Diplodocus was thought to be somewhere about 85 feet. It is believed that these little giants weighed around the same as a current African elephant (perhaps in the area of 4-5 tons), whereas the average weight of a diplodocus was approximately 25 tons. As a result, when compared to everything else, the Nigersaurus can be thought of as a rather modest giant. In comparison to other members of the same family, the Nigersaurus had a smaller body and a shorter neck than its relatives.

The Five Most Interesting Facts about Nigersaurus

1. The short-necked dinosaur known as Nigersaurus is sometimes referred to as having a “long neck.”

The sauropod family is distinguished by its members’ unusually long necks, which is considered to be their most distinguishing trait. Some of the sauropods had necks that were as long as 15 meters, which is six times longer than the neck of the giraffe with the record for largest length. The same cannot be said about the Rebbachisauridae, which included the Nigersaurus and their other closest cousins. This family of dinosaurs is known as the Rebbachisauridae. The majority of Rebbachisaurid had necks that were approximately 10 meters in length or less.

2. The ‘Niger Lizard’

The scientific name for this animal, Nigersaurus, literally translates to “Niger lizard” or “Niger reptile.” Primarily as a result of the discovery of its remains in the region that is now known as the Republic of Niger.

3. The unearthing of baby Nigersaurus fossils

Paleontologist Paul Sereno discovered the bones of a newborn Nigersaurus in the African country of Niger while he was on an excursion there. It was documented that the upper jaw of the infant Nigersaurus that was found “fit on top of a silver dollar,” even though fully grown adults could reach lengths of up to 30 feet.

4. Just the plants

The Nigersaurus belongs to the same family as other sauropods. Any dinosaur that belonged to the subgroup Sauropoda is referred to as a sauropod. The most distinguishing characteristics of these animals were their vast size, lengthy necks and tails, upright posture on four legs, and herbivorous diets (plant eaters.)

5. The discussion on the position

There has been some debate amongst scientists as to whether or not the Nigersaurus would typically carry itself with its head held high. Some researchers initially hypothesized that the skulls of these complex animals would remain permanently angled downward at a 67-degree angle. This would make it simpler for the animals to search for food. However, more recent research from experts casts doubt on this assertion, suggesting that the vertebrae of dinosaurs enabled them to have a significantly broader range of motion. If this is indeed the case, then the Nigersaurus would have behaved more similarly to other sauropods by holding its neck in an upright position.

Which dinosaur had the most number of teeth?

Despite having an amazing number of teeth, the Nigersaurus cannot claim the title of having the most teeth of any animal in history. It was reported that hadrosaurs had as many as 1,400 teeth between all of their mouths. It was stated that their teeth were the most complicated of any teeth found in any living mammal.

Now that we’ve got that out of the way, what kind of dinosaur had 500 teeth? The Nigersaurus. It may not boast the most of any of the dinosaurs, but this strange and beautiful sauropod is getting people talking about dinosaurs. What exactly are you anticipating, seeing as how they have access to all of those teeth?

Frequently Asked Questions

Why the name?

Because of the unusual sound of its name, the Nigersaurus has become the subject of jokes and memes on the internet. However, if you take a closer look, you’ll notice that the term is derived from a scientific classification of dinosaurs. The scientific name for this dinosaur is “Nigersaurus taqueti,” which belongs to the genus “Nigersaurus,” which translates to “Niger reptile” or “a reptile from Niger” (republic of Niger). In addition, the name of the species is a tribute to Phillippe Taqueti, who was the one who initially mentioned this dinosaur.

Have you counted all 500 of its teeth?

To put it simply, yes, technically it did. The skull of the Nigersaurus included 500 long, thin teeth. Despite what you may have heard, none of these teeth were permanent. The 500 teeth that the Nigersaurus had in total were made up of both permanent and replacement teeth!

What did this dinosaur look like that had five hundred teeth?

To summarize, Nigersaurus is related to the sauropods in several ways. It had a more diminutive skull in the past, along with longer hind legs and a tail, just like every other dinosaur. It stood just 9 meters tall and had a femur that was 1 meter long. According to paleontologists, they have to have weighed a total of four tons each. As a result, it’s possible that a Nigersaurus was around the same height and weight as an elephant today. Because of the structure of the rest of its body, it has a short neck that consists of only thirteen cervical vertebrae.

What about the Nigersaurus skull?

In comparison to other dinosaurs that had longer necks, Nigersaurus had four apertures in its skull that are known as fenestra. These openings are more significant. However, the skull’s strength allowed it to withstand the shearing force of the five hundred teeth. In addition to that, it possessed enlarged and bony nostrils.

What did Nigersaurus eat?

Initially, scientists believed that Nigersaurus was a herbivore. However, this particular sauropod is likely to be an herbivore just like the others in its genus. It features a few tiny tooth scratches that are parallel and pitted. This is something that frequently occurs in herbivores, which are animals that derive their nutrition from lower-level plants such as ferns, weeds, and the like. During this period, the grass did not evolve in any way. As a result, this dinosaur with 500 teeth was able to subsist on horsetails, angiosperms, ferns, and other similar plants. However, because of the stiffness of their necks and their height, they did not consume cycads, aquatic plants, or conifers.

Where did Nigersaurus live?

Elhaz Nigersaurus established its roots in Gadoufaoua, Republic of Niger, during the time of the formation of the Tagma group. Low relief fluvial sandstones and the occasional dune of course to medium grain size can be found in this region. In contrast, this area was a floodplain during the Microscopic Cretaceous. There was enough sustenance for it in the shape of low-lying plants in the marshes.
