This morning before school Harper asked
are dinosaur teeth the same as shark teeth?
What a great questions.
We typed the question into Google.
We found this link Harper's Dinosaur Research
and this is the answer to my question
Plant eater dinosaurs and sharks have the same kind of teeth. They have lots of extra teeth that come when their old teeth are broken or old. They got new teeth about once a month.
Meat eaters just kept the same teeth for about three years.
