What Dinosaur Has 500 Teeth?

The Nigersaurus is the dinosaur known for having around 500 slender teeth. It belonged to the Rebbachisauridae family of sauropod dinosaurs and lived during the Early Cretaceous period, nearly 110 million years ago.

Nigersaurus was a plant-eating (herbivorous) dinosaur with a unique dental structure. Its jaw was wide and flat, and its teeth were arranged in tightly packed rows, forming a continuous dental battery — a feature rarely seen in other sauropods.

Key facts:

• Name: Nigersaurus taqueti
• Teeth count: Around 500 replaceable teeth
• Period: Early Cretaceous (~110 million years ago)
• Habitat: What is now the Republic of Niger, Africa

This massive number of teeth helped the Nigersaurus graze efficiently on soft plants growing close to the ground.
