Throughout history and all around the world, our planet has been inhabited by many kinds of strange creatures. Each time these fascinating and mysterious beings lived on this planet, they either evolved further or disappeared into oblivion 🦖.
If you are fascinated by dinosaurs and want to decorate your home with all these beautiful creatures, check out our dinosaur curtains!
Prehistoric life was dominated by large dinosaurs land-living reptiles with distinctive vertebral columns, massive limbs and tails, four-legged stances, and bird-like heads. The traditional view is that all dinosaurs were land animals, but some were at least partially aquatic and there are many features in common with modern crocodiles 🐊.
A dinosaur is one of the most fascinating animals that existed on earth because they are endowed with amazing physical characteristics. Dinosaurs are highly recognized by people because of their hugely sized bodies, gigantic size, and large teeth. The appearance of the dinosaurs is not a deduction, but rather a conclusion is drawn from many observations and scientific research, besides the description of fossil footprints by some researchers.
Famous dinosaurs have always fascinated us. How they lived, how they looked, and, of course, how many teeth they had. The big question here is: which dinosaur had the biggest bite? After all, that is what these prehistoric animals were after, don’t you think?
Our article will reveal the top 10 dinosaurs with the most teeth in the world starting from the infamous 500 teeth dinosaur.
The Top 10 Dinosaurs with The Most Teeth
The dinosaurs are enormous, terrifying creatures that have roamed the earth for millions of years. They were the dominant species on Earth until they were wiped out in a mass extinction event 65 million years ago. The dinosaurs left their mark on the planet and it can still be seen today in the form of fossils and footprints.
Dinosaurs had many adaptations that allowed them to survive in the Jurassic era where they lived. Their large size allowed them to compete with other animals for food and territory, while their sharp teeth allowed them to hunt for prey and defend themselves against predators. Some dinosaurs had up to 500 teeth!
Take a look at our list below to see which dinosaurs had the most teeth!
1. Nigersaurus- The Dinosaur with 500 Teeth
Nigersaurus was a large sauropod dinosaur that lived in what is now Niger during the early Cretaceous period, about 112 million years ago. The Nigersaurus is known to be the dinosaur with 500 teeth.
More complete fossils of the Nigersaurus taqueti weren’t discovered until 1999, during excavations conducted by American paleontologist Paul Sereno.
The name “taqueti” honors the French paleontologist Philippe Taquet, who discovered the first remains of this species when he organized large-scale expeditions to the country in 1976. The name “Nigersaurus” means “reptile from Niger,” alluding to the location where it was discovered. The specific name “taqueti” refers to a subspecies of this species.
The plant-eating dinosaur known as Nigersaurus inhabited what is now the Sahara Desert in Niger. It was about 30 feet in length. The herbivorous dinosaur Nigersaurus shared its habitat with the carnivorous Suchomimus, the plant-eating Ouranosaurus. The skull of the Nigersaurus was very fragile, and it had a very large mouth that was equipped with teeth that were specifically specialized for browsing plants that were low to the ground. This odd dinosaur had a long neck and a snout that was extremely wide and straight-edged, and it had more than 500 teeth that could be replaced.
The skull of this species has been extensively studied by researchers, and based on their findings, they have been able to recreate the animal’s body in its most typical positions. Nigersaurus had a mouth that was directed toward the ground, in contrast to the majority of other dinosaurs, which had mouths that faced forward. The fact that it has very little bone material in its vertebral column is just another one of its morphological quirks.
The National Geographic Museum in Washington, DC, has examples of this group of dinosaurs because they tend to pique the interest of young visitors to the museum.
Nigel, the youngest and smallest relative of the North American Diplodocus, was the smallest dinosaur to ever live, with a length of roughly 13 meters.
His jaw opened and closed like a pair of scissors that measured 12 inches. According to Paul Serno’s findings, “Among all of the dinosaurs, the Nigersaurus Taqueti would earn the Guinness award for the creature with the most teeth, about 500.”
2. Hadrosaur - the dinosaur with 400 teeth
The Hadrosaur is a member of the duck-billed dinosaur family and was one of the last dinosaurs to exist before the extinction of non-avian dinosaurs. It is also known as the duckbill dinosaur. This type of dinosaur had a large number of teeth in its mouth, which were used for chewing plant material. These teeth are often found in fossilized form, giving us an idea about what these creatures looked like when they were alive.
Hadrosaurs could grow to lengths of 10 to 65 feet, and their jaws included hundreds of “cheek teeth,” or almost a thousand in total. This collection of teeth was referred to as a “dental battery.”
The hadrosaur’s tooth structure, which has been described as “possibly the most intricate dental system ever built,” was well fitted to crush down plant material for digestion and may have been a key factor in the creature’s remarkable lifespan on Earth. They possessed parallel stacks of at least six teeth kept together by ligaments rather than losing and replacing teeth like most dinosaurs. Up to 400 teeth total, many of which were located in the rear of the mouth and used for grinding food into smaller pieces before swallowing.
When chewing, a hadrosaur’s top jaw would protrude out to the side, while the lower jaw would slide along the upper teeth.
The Hadrosaur had a short tail and a long neck, which allowed them to reach leaves on high branches. The Hadrosaur was approximately 15 feet long and weighed 2 tons. The hadrosaurs have been discovered in North America, Asia, Europe, Africa, and Australia.
While the specific diet of Hadrosaurs remains a mystery, it is widely accepted that these dinosaurs subsisted only on vegetation. Some pine needles were found in the digestive tract of one specimen.
3. Apatosaurus - the dinosaur with 160 teeth
Apatosaurus is a genus of sauropod dinosaurs that lived about 150 million years ago, in the late Jurassic period. It was a large, long-necked quadrupedal animal with a long, whip-like tail. Apatosaurus had a single nostril at the end of its elongated snout, and its eyes were placed on the sides of its head. It shared the earth with other dinosaurs such as Brontosaurus and Diplodocus.
It was one of the largest herbivores to ever walk the earth, reaching up to 40 feet (12 meters) long and weighing up to 30 tons. The Apatosaurus had a long neck, which could grow up to 20 feet (6 meters), and a long tail, which could grow up to 10 feet (3 meters) long. The Apatosaurus had a large skull with approximately 80 teeth on each side of its mouth!
Apatosaurus was a massive herbivore with an odd lack of chewing ability, despite their abundance of chisel-shaped teeth. Its diet was thought to consist primarily of plants, and it was supposed to consume as a whole. It was theorized that the creature stripped leaves and other vegetation off trees with its sharp teeth.
The Apatosaurus was an enormous dinosaur with a long neck and tail that walked on four powerful legs. The size of their heads was disproportionately small to the rest of their bodies. They were classified under the genus Sauropod, which included some of the biggest dinosaurs ever. Thanks to their long necks, they could forage high in the trees for leaves and other vegetation.
Apatosaurus skulls are hard to come by because their bones are so brittle and fragile. The Carnegie Museum of Natural History in Pittsburgh, Pennsylvania, houses a cast of the specimen with the original, both of which were discovered in the Carnegie Quarry.
4. Mapusaurus - the carcharadontosauridae
As its name suggests, the Mapusaurus, or “Earth Lizard,” was closely linked to the Giganotosaurus, the biggest known carnivorous dinosaur. Mapusaurus, like the Giganotosaurus, belonged to the Carcharadontosauridae, a group of predatory therapod dinosaurs with hollow bones and three toes. These dinosaurs were often much larger than Tyrannosaurus rex. Adult Mapusaurus was around 3 tonnes in weight and 40 feet in length. They possessed robust legs and a muscular tail.
Bones from at least seven Mapusaurus, all of different ages and sizes, were found together in one location. Researchers, Coria and Currie theorized that this would reflect a long-term, potentially accidental buildup of corpses (a kind of predator trap) and that it might reveal insights into the behavior of Mapusaurus.
Similar to the Giganotosaurus in both size and appearance, the Mapusaurus displayed curved, flat teeth with a serrated edge, perhaps used for shredding the flesh of victims. Multiple bites from such teeth, it has been hypothesized, might have brought down larger prey for the Mapusaurus in packs.
5. allosaurus - the dinosaur with huge teeth
The intriguing Allosaurus was widespread over the continent of North America. The Allosaurus was a massive, amazingly fast dinosaur, measuring more than 33 feet in length and traveling at speeds of 19 to 34 miles per hour. The most notable feature, though, was its mouth, namely its enormous gape. Seeing the power and impressive anatomy of these reptiles, one might wonder how did dinosaurs die.
The mouth gape of this monster was broader than a straight angle, measuring more than 31 inches and an angle of 79 to 92 degrees, making it bigger than the typical gape of the Tyrannosaurus rex, which measured around 80 degrees. “Double-hinged jaw” is a term used to describe this gape. This enormous gape is exclusive to carnivores and is thus perfect for the fast ambush predator Allosaurus.
The Allosaurus’s bite was especially lethal because of the serrations on its teeth. This animal’s teeth were always in excellent shape since they were always renewed and growing. Approximately 32 of the Allosaurus’ 3–4-inch long teeth were utilized at once for both hunting and defense.
The discovery that the Allosaurus utilized its skull like an axe, “throwing” it out vertically with jaws open to slice into other dinosaurs, was, however, the most exciting part of the Allosaurus mouth. This would result in the enemy dinosaur suffering significant blood loss and a significant reduction in their strength. This method’s power was bolstered by the strength of the practitioner’s neck muscles. When under assault, this dinosaur could rapidly duck its head and body out of the way.
6. giganotosaurus - The largest carnivorous dinosaur
Giganotosaurus is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 97 million years ago. It is the biggest species of allosauroid dinosaur and one of the largest meat-eating dinosaurs ever. For a long time, Tyrannosaurus was the largest known dinosaur, but fossils of Carcharodontosaurus and Spinosaurus hinted that they could have been able to compete with the huge coelurosaur. When the work of Argentine paleontologists Rodolfo Coria and Leonardo Salgado was published in the late 1980s and early 1990s, it showed the presence of a new meat-eater larger than any previously known tyrant lizard. The gigantic dinosaur was given the scientific name Giganotosaurus carolini.
The generic name means “giant southern lizard” from the Greek gegeneios ‘of northern origin’ and sauros ‘lizard’.
Giganotosaurus was among the largest non-titanosaurian terrestrial carnivores, measuring about 14 meters (46 ft) in length and weighing around 7 metric tons (7.7 short tons).
The Giganotosaurus would use its teeth, which resembled knives, to slice its victims, which were sauropods. The Giganotosaurus would continue to stab the sauropod until it finally succumbed to its wounds and bled to death. After that, the Giganotosaurus would consume its meal. The
7. Carcharodontosaurus - the dinosaur with 80 teeth
Carcharodontosaurus (pronounced Kar-ka-ROD-on-to-SORE-us) is a genus of carnivorous carcharodontosaurid dinosaurs that existed during the Cretaceous Period in what is now North Africa. It was one of the largest predators of its time and among the largest known terrestrial carnivores.
It is possible that Carcharodontosaurus was the biggest and most threatening of all the theropod dinosaurs that walked the earth throughout the Cretaceous period. The theropod dinosaurs belonging to the genus Carcharodontosaurus were the dominant species in northern Africa between 93 and 100 million years ago, during the middle of the Cretaceous Period. At this time, it is known that this genus had two enormous species, both of which were among the biggest predatory dinosaurs ever discovered.
Carcharodontosaurus had two rows of big, sharp teeth, one on top and one on the bottom in each jaw. The top row was larger than the bottom row, but they were all huge! An adult Carcharodontosaurus could have had up to 80 large teeth.
Comparable in size to or bigger than that of Tyrannosaurus, its skull was one of the biggest yet discovered. The teeth are rather thin in width, have a little inward bend, and have minute enamel wrinkles that radiate out from the carinae. It lived at the same time as Spinosaurus, but as a result of their dissimilar tooth structures, it is clear that these two enormous carnivores feasted on distinct kinds of animals. A pair of short horns grew above each eye, which may have been used for display or defense.
The family Carcharodontosauridae may be traced back to the same group as the late Jurassic dinosaur Allosaurus, which is known as Carnosauria, according to taxonomists. The enormous size of these dinosaurs, their extra-large nostrils, and the nasal and maxillary hollows that drastically reduced the weight of their heads are some of the distinguishing characteristics of this group.
8. Ankylosaurus - the dinosaur with 72 teeth
Ankylosaurus was a large, armored dinosaur. It had a small head, a short tail, and spikes on its body. Ankylosaurus was one of the last ankylosaurs to walk the earth 65 million years ago.
Ankylosaurus was up to 20 feet (3.3 meters) long and weighed up to 4 tons (8,000 kg). The dinosaur’s body was covered with bony plates called osteoderms, which were embedded in its skin. These plates formed a protective shield that covered its back and sides. Ankylosaurus also had two horns above its eyes and two smaller ones behind them.
The main weapon of this dinosaur was its tail club, which could swing at predators or prey from below. The club was made up of several bones from the hip region fused into one big bony knob or ball that ended in a thick knob or ball at the end for added damage when swung against other dinosaurs!
The Ankylosaurus was a plant-eater and had roughly 72 teeth fashioned like leaves. The teeth were narrow and built from cusps that resembled huge serrations, with a cingulum that was enlarged at the base. It is quite likely that the teeth were employed to harvest plants, maybe including ferns, cycads, and angiosperms, with very little chewing required. The tooth morphology of ankylosaurs, stegosaurs, and pachycephalosaurs was the most basic and rudimentary of all ornithischian dinosaurs.
9. Tyrannosaurus Rex - the dinosaur with 60 teeth
The fearsome Tyrannosaurus rex, sometimes known as the “King of the Tyrant Lizards,” must serve as our initial example of a formidable prehistoric predator.
The Tyrannosaurus rex is a dinosaur that lived during the Cretaceous period. It was one of the largest predators ever to walk on land, reaching up to 12 meters in length and weighing up to 6 tons. The T. rex had a bite force of over 10,000 pounds per square inch, which is more than seven times greater than that of an African lion or any other living carnivore.
The T. rex had over 60 teeth in its mouth at any given time, each tooth being about 7 centimeters long. Teeth were constantly being replaced during their lifetime; as soon as one tooth wore down and was replaced by another tooth, it would be shed and left behind on the ground for paleontologists to discover millions of years later!
This meat-eating behemoth possessed the longest teeth of any dinosaur at 12 inches long, with an average of 50 to 60 conical, chisel-shaped teeth that were spaced more closely together in the front than on the sides. Supposedly, their front teeth clutched and tugged, while their side teeth tore through the flesh of the victims. T. rex not only possessed the biggest teeth but also the strongest biting force of any terrestrial animal, with the ability to break bones with up to six tonnes of pressure in a single bite.
The Tyrannosaurus rex was a massive dinosaur that could reach heights of 40 feet, weighed 6-8 tonnes, and moved sturdily on two powerful legs. Its forelimbs were noticeably shorter than the rest of its body and seem to have served little use. The scientific community is divided about whether T. rex was primarily a scavenger, a big predator, or both.
10. velociraptor - the dinosaur with 60 sharp teeth
Velociraptor is a genus of dromaeosaurid theropod dinosaur which lived in Mongolia, China, and North America during the Late Cretaceous Period. It was one of the first dinosaurs to have its DNA tested, and it was found to be more bird-like than most scientists expected.
The Velociraptor was a little carnivorous dinosaur, about the size of a small turkey, in contrast to the intimidating appearance of the Tyrannosaurus rex. However, this does not make their teeth any less pointy in the least! The upper and lower jaws of the Velociraptor each contained between 27 and 30 serrated teeth that were evenly spaced away from one another. The combination of its razor-sharp teeth and lethal claws made it the perfect predator for smaller dinosaurs, reptiles, and amphibians, making it excellent for scavenging and hunting.
Velociraptors had long arms with sharp claws on each finger. It was covered in feathers, but they were not used for flight; instead, they may have displayed features or insulation against heat loss. The tail was stiffened by ossified tendons, which would have given it some balance when making sharp turns.
From the long-necked Diplodocus and the meat-eating Allosaurus to the sharp-toothed Megalosaurus, Thescelosaurus, and Spinosaurus. These creatures were hunting in packs or with others, they were quick and deadly. The top ten dinosaurs with the most teeth are listed above, each Dino has spectacular evidence of their existence during their battle for dominance over the Earth during a period of geological time that lasted for 145 million years.
