From the brains behind brains on, Bum and a Vub. Bum and a Vub comes to you from APM Studios. I'm Devin Thompson and I'm a brontosaurus. Um... Mama? Mama! Yes, honey? Can I have a salad? Yes, just go ahead and take a big old bite of that horsetail fern over there. Okay! Ow!
Mama! Yes, Devin? There was a rock in there. Oh, no! I lost my tooth. That's okay, honey. It's just a normal part of life. Okay! Well, that's a great question. Let's ask a paleontologist. My name is David. I am from Denver, Colorado. My question is, did dinosaurs have baby teeth?
Dinosaurs could actually have as many teeth as they needed as they broke off or fell out. My name is Shana Montaneri, and I am a paleontologist. So if you were a big T-Rex and you ate something big and it broke your tooth, you could actually grow another tooth. But since the teeth were so big, like with a T-Rex tooth that can be like nine inches long, that's going to take a really long time to grow back in. You'll be waiting weeks or months for that one.
Some dinosaurs had different teeth, not just big sharp ones with serrated kind of bumpy edges that made them like a steak knife like T. rex had, but there were lots of plant-eating dinosaurs that had different shaped teeth. Hadrosaurs, for example, had something that was like a big flat plate for grinding. Sauropod dinosaurs had
have teeth that look like pegs that are round that are good for eating plants and plants actually will flatten out your teeth because as you eat trees and bushes and things there's a lot of dirt and so that can actually grind down the teeth so dinosaurs were more like reptiles where their teeth could fall out and another one would grow um um
Yes, Devin? Do all dinosaurs have teeth? Actually, no. Have you heard of orthomimids? I think so. These are a group of dinosaurs that eat plants, insects, small lizards, and small mammals. And they use their gums to grind their food down into small bits that they can digest. So they really don't need teeth. Wow, neat! Okay, I'm going to go eat more friends now. Bye, Mom! I love you! Bye!
