With birds it’s all beaks.

That's only for the last 100 million years. Before that it's all teeth too.

Birds had teeth 100 million years ago, then suddenly they didn't?

[-] Bonehead@kbin.social 8 points 11 months ago

Not suddenly, it likely took a few million years to lose them. But essentially, yes.

Here is an excellent video that explains why the non-beaked birds died out: https://www.youtube.com/watch?v=M1TanPmCckM
