It's time once again for the Moment of Science Pop Quiz. Ready? Here goes.   Do birds have teeth?
Sure, you can laugh, but what's the answer? No? Maybe? Have you ever looked?
In fact, the correct answer is: not any more.
Some modern day birds have ridges1 or notches2 in their beaks3 that can function a little bit like teeth, but they don't actually count as teeth. But the idea of a toothy bird is not so ridiculous as it seems. In fact, if you lived about 100 million years ago, toothy birds would be no laughing matter.
Surprisingly, the first true bird seems to have been closely related to the dinosaurs4. It is called the Archaeopteryx and lived about 150 million years ago. Archaeopteryx was the size of a modern day crow but had a full set of chompers. Presumably they weren't used for eating seeds.
After this character came on the scene birds began to grow bigger and bigger. A lot of these species had teeth. Big, shiny, pointy teeth. These were scary birds we're talking about here. Some of these prehistoric5 fanged6 birds grew to be larger than the modern-day ostrich7. One of them laid an egg more than a foot in length. Imagine being chased by a fanged ostrich. It's enough to make you stay in your own century.
Thankfully, no fanged birds exist today, and all modern birds are smaller than ostriches8. Don't think that means birds are no longer a successful species, though. Quite to the contrary: there are about twenty-five birds for every single person now alive on the earth.
