Which dinosaur had more than 500 teeth in its unusually broad jaw?
Correct!
The herbivorous Nigersaurus had an extremely broad, almost straight jaw with more than 500 active and replacement teeth. These formed dental batteries and were replaced very quickly.
Nigersaurus lived about 110 million years ago in what is now the Sahara in Niger. Its broad, downward-facing mouth was probably adapted for grazing low vegetation close to the ground.
