三角龍

The idea that it had up to 800 teeth, with only a fraction in use while the rest were replaced, is such a wild detail. My kid now repeats it to anyone who'll listen.

I love learning that triceratops constantly replaced its teeth—over 800 in a lifetime. It’s amazing how only a few were actually used at once, making it such an efficient herbivore.

Never knew something could pack 400 to 800 teeth into one jaw. My kid keeps counting them and losing track every time, which honestly makes it more fun. The whole replace-the-worn-ones-as-you-go detail is the part we talk about most.
