A new study shows that teeth are not too good for you if you're a dinosaur trying to not go extinct.<br>
<br>
Around 66 million years ago, a time known as the end-Cretaceous, there was a massive extinction of life, with around 75% of all known species dying off. Perhaps most well-known at this time is the extinction of the non-bird line dinosaurs.<br>
