How Often Did Nigersaurus Replace Its Teeth?

The Nigersaurus had one of the fastest tooth replacement rates among dinosaurs. According to paleontologists, it could replace its entire set of teeth approximately every 14 days.

This rapid replacement was necessary because the dinosaur’s delicate teeth wore down quickly while grazing on gritty, ground-level plants that contained sand and soil particles.

Tooth replacement details:

• Each tooth row had multiple backup teeth ready to emerge.
• Replacement occurred continuously, ensuring efficient feeding.
• Scientists observed up to nine replacement teeth stacked below each functional tooth.

This unique adaptation highlights how Nigersaurus evolved a self-renewing dental system to maintain its feeding efficiency throughout life.
