what dinosaur has 500 teeth

#1
The dinosaur with 500 teeth is called Edmontosaurus annectens, which was a species of hadrosaurid dinosaur that lived during the Late Cretaceous period. This dinosaur had a series of over 500 teeth in its jaw, but they were not all in use at the same time. Edmontosaurus annectens had a tooth battery, meaning that as the teeth at the front of its jaw wore down, new teeth would move forward to replace them. This allowed the dinosaur to continuously grind up tough plant material for food.
