What dinosaur has 500 teeth? If you’re imagining a terrifying carnivore, think again! Meet the Nigersaurus, a unique, plant-eating dinosaur that roamed what is now the Sahara Desert 110 million years ago. Known as the “Mesozoic Cow,” this gentle giant grazed on ground-level plants with its unusually wide mouth packed with over 500 replaceable teeth. But what makes this dinosaur truly remarkable? Let’s dig into the story of Nigersaurus and uncover its fascinating features.

The Discovery of Nigersaurus
The first remains of Nigersaurus were discovered in Niger in the 1970s by French paleontologist Philippe Taquet. However, it wasn’t until 1999 that this dinosaur was formally named by renowned paleontologist Paul Sereno. Nicknamed “the dinosaur with 500 teeth,” Nigersaurus stood out due to its delicate skull and jaw structure, which resembled a vacuum cleaner when viewed from above.
Unique Features of Nigersaurus
1. Over 500 Replaceable Teeth
Nigersaurus had dental batteries—rows of vertically stacked, replaceable teeth. Its upper jaw contained 60 columns, while its lower jaw had 68 columns, totaling over 500 teeth. These teeth were perfectly adapted for shearing through ground-level vegetation like ferns and horsetails. Amazingly, each tooth was replaced approximately every 14 days to keep up with its heavy feeding habits.
2. Lightweight Build
Despite its size, Nigersaurus was lightweight for a sauropod, measuring about 30 feet long and weighing roughly 4 tons—comparable to an elephant. Its bones were filled with air cavities, making its skeleton light and efficient for movement.
3. Unusual Skull and Muzzle
Its broad, straight-edged muzzle was unlike any other dinosaur, with teeth concentrated at the front of its mouth. This allowed Nigersaurus to efficiently scoop up vegetation while grazing.
4. Adaptations for Survival
With its large eye sockets and excellent vision, Nigersaurus could keep a lookout for predators like Sarcosuchus, the massive “supercroc” that shared its habitat. However, its sense of smell was less developed, reflecting its reliance on vision for safety.
The Environment Nigersaurus Called Home
During the mid-Cretaceous period, the Sahara Desert was a lush, riverine environment teeming with life. Nigersaurus coexisted with other dinosaurs like the predatory Suchomimus, herbivores such as Ouranosaurus and Lurdusaurus, and the fearsome Sarcosuchus. Its ground-level feeding habits meant Nigersaurus didn’t compete with taller herbivores that browsed on treetops, making it uniquely suited to its niche.
The Internet Fame of Nigersaurus
In recent years, Nigersaurus has gained unexpected internet fame, largely due to the viral question, “What dinosaur has 500 teeth?” Its unusual name and striking appearance have sparked curiosity, making it a favorite topic for memes and dinosaur enthusiasts. While its fame may have started as a joke, it has introduced millions to the fascinating world of paleontology.
Why Nigersaurus Matters
The study of Nigersaurus not only highlights the incredible diversity of dinosaurs but also sheds light on how these creatures adapted to their environments. Its discovery has inspired a new generation of paleontologists and continues to capture the imagination of dinosaur fans worldwide.
