In this article, we’ll explore the science behind the dinosaur, explain why it became a meme, cover how to pronounce its name correctly, and separate facts from internet humor.
What Dinosaur Has 500 Teeth?
The dinosaur famously known for having around 500 teeth is called Nigersaurus.
Nigersaurus lived approximately 115 million years ago during the mid-Cretaceous period. It was a long-necked sauropod dinosaur discovered in what is now Niger, Africa, which is how it got its name.
Unlike the towering, tree-top eaters you might imagine, Nigersaurus stayed low to the ground and had a mouth perfectly designed for grazing.

Basic Facts About Nigersaurus
-
Diet: Herbivore
-
Length: About 30 feet
-
Weight: Roughly 4 tons
-
Era: Cretaceous period
-
Location: Sahara Desert (modern-day Niger)
What truly sets Nigersaurus apart is its jaw. It had more than 500 narrow teeth arranged in rows, constantly replacing themselves—much like a conveyor belt.
Why Did Nigersaurus Have 500 Teeth?
Nigersaurus wasn’t built to bite or tear. Instead, it was designed to vacuum up plants near the ground.
Its teeth were perfect for:
-
Cropping soft vegetation
-
Grazing ferns and low plants
-
Rapid tooth replacement due to wear
At any given time, only a fraction of its 500 teeth were visible, while replacements waited behind them. This made Nigersaurus one of the most efficient plant-eaters of its time.
