When people ask, “What dinosaur has 500 teeth?” the answer is simple but fascinating: Nigersaurus. This unusual dinosaur has intrigued scientists and dinosaur enthusiasts alike due to its bizarre dental arrangement and unique physical characteristics. Let’s dive deep into everything we know about this remarkable creature.
Introduction to Nigersaurus
Nigersaurus taqueti is a genus of sauropod dinosaur that lived around 110 million years ago during the middle Cretaceous period. Its fossils were discovered in the Republic of Niger, in West Africa—hence the name Nigersaurus, which means “Niger reptile.”
1. The 500 Teeth Mystery
The most famous fact about Nigersaurus is that it had over 500 teeth—precisely 500+ replaceable teeth, neatly arranged in rows.
Why So Many Teeth?
Nigersaurus was a herbivore, meaning it ate plants. Its teeth were specialized for:
- Ground-level feeding: Unlike many dinosaurs that ate from trees, Nigersaurus grazed on low-lying plants like ferns.
- Shearing soft vegetation: Its teeth were designed to snip and strip leaves with ease.
- Constant replacement: Nigersaurus had multiple sets of teeth that were continuously replaced every 14 days or so.
This high turnover of teeth was necessary due to the constant wear from feeding close to the ground.
2. Physical Features of Nigersaurus
Here are some key characteristics:
- Length: Around 9–10 meters (30 feet) long.
- Weight: About 4 tons—roughly the size of an elephant.
- Neck: Shorter than most sauropods, despite being in the same family.
- Skull: Light and hollow with large openings.
- Mouth: Extremely wide, with a jaw shaped like a vacuum cleaner’s intake.
Interestingly, Nigersaurus is the only known dinosaur with teeth located at the front of its jaw, extending across its entire width.
3. Discovery and Naming
Nigersaurus was first mentioned in scientific literature in 1976, but it wasn’t until 1999–2000 that more complete remains were found by Dr. Paul Sereno and his team during expeditions to Niger.
In 2005, it was officially named Nigersaurus taqueti, in honor of French paleontologist Philippe Taquet, who first found the bones in the 1970s.
4. Classification
- Kingdom: Animalia
- Phylum: Chordata
- Clade: Dinosauria
- Order: Saurischia
- Suborder: Sauropodomorpha
- Family: Rebbachisauridae
- Genus: Nigersaurus
- Species: N. taqueti
It belonged to the same group as well-known long-necked dinosaurs like Diplodocus but was far more peculiar.
5. Diet and Lifestyle
Nigersaurus’s diet consisted primarily of:
- Ferns
- Horsetails
- Angiosperms (early flowering plants)
Its low-slung neck and wide, flattened snout allowed it to graze efficiently like a prehistoric lawnmower. It likely spent most of its time with its head close to the ground.
6. Vision and Sensory Abilities
Nigersaurus had relatively large eye sockets, suggesting good eyesight, possibly to help it stay alert for predators like Suchomimus, a large carnivorous dinosaur that shared its environment.
7. Controversies and Internet Fame
Nigersaurus gained sudden internet fame due to memes and viral searches like “What dinosaur has 500 teeth?” While the facts are scientifically accurate, it’s important to approach the topic with respect and curiosity rather than humor or misinformation.
8. Where Can You See Nigersaurus Today?
Reconstructed skeletons and fossil exhibits of Nigersaurus can be found in several museums around the world, including:
- National Geographic Museum
- Chicago’s Field Museum
- Natural History Museum in Niamey, Niger
Conclusion
Nigersaurus stands out in the dinosaur world thanks to its unusual dental structure, ground-level feeding style, and short-necked sauropod build. With over 500 constantly replacing teeth and a body built for grazing, it was one of the most unique herbivores to ever walk the Earth.
FAQs: What Dinosaur Has 500 Teeth?
Q1. What dinosaur has 500 teeth?
A: The dinosaur known for having 500 teeth is Nigersaurus. It was a plant-eating sauropod that lived about 110 million years ago during the Cretaceous period.
Q2. Did Nigersaurus really have exactly 500 teeth?
A: Nigersaurus had over 500 teeth, including replacement teeth waiting in line. At any given time, it had around 50 rows of teeth in its upper and lower jaws, constantly replenished as they wore down.
Q3. What were the teeth used for?
A: Nigersaurus used its teeth for grazing low-lying plants like ferns and horsetails. The teeth were thin and adapted for snipping soft vegetation close to the ground.
Q4. Were Nigersaurus’s teeth sharp?
A: No, they weren’t sharp like a predator’s. They were more like scissors—ideal for clipping and shredding plants rather than biting or tearing meat.

Q5. Why did Nigersaurus need so many teeth?
A: Because it fed constantly and close to the ground, its teeth wore down quickly. Having so many teeth—and replacements ready—helped it maintain efficient feeding without pause.
Q6. Where were Nigersaurus fossils found?
A: Fossils of Nigersaurus were discovered in the Republic of Niger, a country in West Africa. That’s where its name comes from.
Q7. Who discovered Nigersaurus?
A: The first bones were discovered by Philippe Taquet in the 1970s. A more complete skeleton was found in 1999 by Dr. Paul Sereno and his team.
Q8. What did Nigersaurus look like?
A: It had a short neck, long tail, and a wide, flattened snout. It measured about 30 feet long and weighed around 4 tons, similar to a modern elephant.
Q9. Was Nigersaurus dangerous?
A: No, Nigersaurus was a gentle herbivore. It didn’t have claws or sharp teeth for fighting and likely avoided conflict altogether.
Q10. Can I see a Nigersaurus skeleton today?
A: Yes! Reconstructed skeletons and fossils of Nigersaurus are displayed in several museums, including the National Geographic Museum and Chicago’s Field Museum.
Q11. Is the “500 teeth” dinosaur meme offensive?
A: The meme has sometimes been used inappropriately online. While the dinosaur facts are real, it’s important to approach topics like this with scientific curiosity and respect, not humor based on stereotypes or misinterpretation.
